DSEI2X121-02P

Diode Arrays Overview

The DSEI2X121-02P is a Fast Recovery Epitaxial Diode (FRED) manufactured by IXYS. It features an international standard miniBLOC package, compatible with ISOTOP mounting. The device contains two independent FRED chips within a single enclosure. Key electrical characteristics include a peak reverse repetitive voltage of 200 V and a maximum continuous forward current of 123 A per diode. The component exhibits a very short recovery time of 50 ns and a low peak reverse recovery charge. It operates within a junction temperature range from -40°C to +150°C.

Diode Arrays Feature Summary

• Contains two independent fast recovery epitaxial diodes in one package
• Features planar passivated chips for enhanced reliability
• Provides extremely low switching losses due to soft recovery behavior
• Offers high isolation voltage capability between terminals

Diode Arrays Applications

• High-frequency power conversion circuits
• Industrial motor drive inverters
• Uninterruptible power supply (UPS) systems
• High-power DC-DC converters

Diode Arrays Procurement Notes

Verify the specific suffix 'P' against official IXYS documentation to confirm pinout and mechanical compatibility, as variations exist within the DSEI2X121 series. Ensure the procurement source provides valid traceability certificates. Confirm that the miniBLOC package dimensions match the target heatsink interface requirements before finalizing orders.

Diode Arrays Selection Notes

Select this component when dual isolated rectification is required in a compact panel-mount form factor. The 200 V rating suits low-voltage, high-current applications. Consider the 50 ns recovery time for switching frequencies where standard rectifiers would incur excessive thermal loss. Evaluate the 123 A continuous current capacity against the system's RMS load requirements.

Diode Arrays Part Context

This part belongs to the DSEI2X121 series of fast recovery diodes designed for high-power density applications. The series utilizes epitaxial technology to achieve superior switching performance compared to conventional diffused diodes. The miniBLOC packaging allows for direct screw mounting to cold plates or heatsinks, facilitating efficient thermal management in industrial power electronics environments.

Diode Arrays Replacement Considerations

Official substitutes within the same family include DSEI2X121-02A and DSEI2X121-02P. Verify electrical equivalence and mechanical footprint compatibility before substitution. Cross-referencing with other manufacturers requires careful validation of reverse voltage, forward current, and recovery time specifications.
