DSEP2X31-04A

Diode Arrays Overview

The IXYS DSEP2x31-04A is a HiPerFRED fast recovery diode with a maximum repetitive reverse voltage of 400 V and a maximum forward current of 30 A. It features a typical reverse recovery time of 30 ns and a peak non-repetitive forward surge current rating of 280 A. The device utilizes an SOT-227B (minibloc) package with a copper base plate for panel mounting, providing an isolation voltage of 3000 V.

Diode Arrays Feature Summary

• Soft reverse recovery behavior designed to minimize electromagnetic interference and reduce turn-on losses in commutating switches.
• Internal DCB isolated copper base plate ensures high electrical isolation between terminals and the backside.
• Planar passivated chips provide very low leakage current and reliable avalanche voltage ratings.

Diode Arrays Applications

• Free wheeling diodes
• Rectifiers in switch mode power supplies
• Snubber diodes
• Antiparallel diodes for high frequency switching devices

Diode Arrays Procurement Notes

Verify the component status as phase-out before procurement. Confirm that the ordering suffix does not alter functional specifications unless explicitly documented. Ensure the supplier provides original manufacturer datasheets to validate technical parameters against the official DSEP2x31-04A specification sheet.

Diode Arrays Selection Notes

Select this component for applications requiring soft recovery characteristics to lower EMI/RFI noise. The SOT-227B package facilitates direct heatsink mounting via the isolated copper base. Consider the 400 V rating and 30 A continuous current limits when designing thermal management systems for SMPS or UPS environments.
