IXYS DSSX110 Industrial Schottky Rectifier for Power Systems

IXYS DSSX110 Industrial Schottky Rectifier: Powering the Smart Factory Data Chain

The IXYS DSSX110 is a high-performance Schottky Diode Rectifier rated at 10A / 100V, engineered for demanding industrial power supply applications where low forward voltage drop, fast switching recovery, and thermal stability are non-negotiable. In modern smart factory environments, reliable DC power conversion is the invisible backbone that keeps every node of the automation network alive — from field-level sensors and actuators to PLC controllers, remote I/O modules, HMI panels, SCADA gateways, and edge computing nodes. The DSSX110 sits at the heart of this power infrastructure, ensuring that every device in the data chain receives clean, stable, and uninterrupted power.

Connected Automation Data Flow: Where DSSX110 Powers the Industrial Network

In a fully connected smart factory, data flows continuously between dozens of device layers — and every single one of them depends on stable DC power conversion. The IXYS DSSX110 Schottky rectifier is deployed in the switched-mode power supplies (SMPS) and DIN-rail power units that energize this entire ecosystem.

At the field level, Siemens ET 200SP remote I/O modules and Phoenix Contact Axioline F distributed I/O units rely on 24VDC rail power derived from rectifier-based PSUs. The DSSX110’s low forward voltage drop minimizes heat generation in these compact DIN-rail enclosures, extending the operational life of the power supply and the connected I/O nodes. Signal data from pressure transmitters, flow sensors, and proximity switches is collected at these I/O nodes and forwarded upstream via PROFIBUS DP or PROFINET to the PLC controller layer.

At the controller level, Siemens S7-1500 PLCs and Allen-Bradley CompactLogix L3x controllers process real-time field data and execute control logic. Their 24VDC power modules — often built around Schottky rectifier output stages — must maintain voltage stability within ±1% to prevent CPU faults or communication timeouts on the EtherNet/IP network. The DSSX110’s 100V blocking voltage provides adequate headroom for transient suppression in these environments.

Moving up to the drive layer, Danfoss VLT FC302 variable frequency drives and Yaskawa GA700 inverters incorporate Schottky diodes in their internal DC bus pre-charge and freewheeling circuits. Fast switching recovery of the DSSX110 reduces reverse recovery losses at the switching frequencies (typically 4–16 kHz) used in modern PWM motor control, contributing to overall drive efficiency and reducing EMI on the factory network.

At the network infrastructure layer, Hirschmann RS20 industrial managed switches and Moxa EDS-510E Ethernet switches form the backbone of the plant’s Industrial Ethernet topology. These switches are powered by redundant 24VDC supplies — again, rectifier-dependent — and carry PROFINET, Modbus TCP, and EtherNet/IP traffic between PLCs, HMIs, and SCADA servers. Network uptime is directly tied to PSU reliability, making the DSSX110’s thermal performance a critical factor in overall OEE.

At the visualization and supervisory layer, Weintek cMT-SVR SCADA gateways and Siemens SIMATIC HMI TP1200 Comfort panels aggregate process data from multiple PLCs and present it to operators in real time. These devices draw power from the same 24VDC distribution bus, and any ripple or dropout caused by a failing rectifier stage can result in HMI screen freezes, lost historian data, or SCADA alarm floods. The DSSX110 ensures the rectification stage remains efficient and thermally stable even under continuous 10A load.

Finally, at the edge and cloud connectivity layer, Advantech ECU-1251 edge gateways running OPC-UA clients collect aggregated data from SCADA and push it to MES or cloud analytics platforms. These gateways are powered by compact SMPS units where the DSSX110’s small footprint and high efficiency make it an ideal rectifier choice for space-constrained industrial enclosures.

Solving Power Isolation in Industrial Sites: The Hidden Risk Behind Data Downtime

Many industrial engineers focus on network protocol compatibility and PLC programming when troubleshooting data flow issues — but a significant proportion of unplanned downtime originates in the power supply layer. A degraded rectifier diode in a 24VDC PSU can cause voltage sag under load, introducing noise onto the DC bus that manifests as intermittent Modbus TCP timeouts, PROFINET communication errors, or HMI disconnections. These symptoms are often misdiagnosed as network configuration problems, leading to wasted engineering hours.

The IXYS DSSX110 addresses this root cause directly. Its Schottky junction technology delivers a forward voltage drop typically 30–40% lower than standard PN-junction rectifiers, reducing conduction losses and heat buildup in the PSU. This translates to a more stable DC output voltage under dynamic load conditions — exactly what is needed when a PLC simultaneously executes a motion control sequence, logs data to a historian, and responds to an HMI operator command.

For multi-line production facilities where data silos between production cells are a persistent challenge, standardizing on high-quality rectifier components like the DSSX110 across all PSU units ensures a uniform power quality baseline. This makes it easier to implement plant-wide remote power monitoring via SCADA, where PSU output voltage and current are tracked as process variables alongside temperature, pressure, and flow — enabling predictive maintenance before a PSU failure causes a line stoppage.

The DSSX110 also supports system scalability. As factories expand their automation footprint — adding new remote I/O drops, additional HMI stations, or new edge gateway nodes — the existing PSU infrastructure can be upgraded with DSSX110-based rectifier modules without redesigning the entire power distribution architecture. Its 100V rating provides sufficient margin for 48VDC bus applications as well, future-proofing the installation for next-generation industrial power architectures.

Every unit of the IXYS DSSX110 supplied by ZYPLC undergoes outgoing inspection and is covered by a 12-month warranty. Stock is maintained for immediate dispatch via DHL Express or FedEx International Priority, with full export documentation for cross-border industrial procurement.

Industrial Power & Connectivity FAQ

Q1: Is the IXYS DSSX110 suitable for use in 24VDC industrial power supplies powering PROFINET networks?
Yes. The DSSX110’s 100V reverse voltage rating and 10A average forward current make it well-suited for the output rectifier stage of 24VDC DIN-rail power supplies used in PROFINET, EtherNet/IP, and Modbus TCP network infrastructure. Its low forward voltage drop minimizes output ripple, which is critical for maintaining stable communication on noise-sensitive industrial networks.

Q2: How does the DSSX110’s switching speed affect motor drive and inverter applications?
The DSSX110’s ultra-fast reverse recovery characteristic reduces switching losses in high-frequency SMPS and motor drive auxiliary power circuits operating at 10–100 kHz. This improves overall drive efficiency and reduces high-frequency EMI that could otherwise interfere with industrial Ethernet communications in the same enclosure.

Q3: Can the DSSX110 be used in redundant power supply configurations for SCADA and HMI systems?
Yes. The DSSX110 is commonly used in ORing diode configurations for redundant 24VDC power supplies, where two PSU outputs are combined to provide uninterrupted power to SCADA servers, HMI panels, and network switches. Its low VF ensures minimal voltage drop in the ORing circuit, maintaining full output voltage to the load even during PSU switchover.
