DSEP2X31-03A

Diode Arrays Overview

The IXYS DSEP2X31-03A is a HiPerFRED epitaxial diode featuring soft recovery characteristics. It provides a maximum repetitive reverse voltage (Vrrm) of 300 V and a continuous forward current (If) of 30 A. The device exhibits a peak non-repetitive forward surge current (Ifsm) of 300 A, with a maximum forward voltage (Vf) of 1.4 V and a peak reverse current (Ir) of 12.5 A. Operating within a temperature range of -40°C to 125°C, it utilizes an isolated configuration in a panel-mount SOT-227 package.

Diode Arrays Feature Summary

• HiPerFRED epitaxial technology ensures extremely low switching losses and very short recovery time.
• Soft recovery behavior minimizes electromagnetic interference during high-frequency operation.
• Planar passivated chips provide robust isolation voltage capabilities.

Diode Arrays Applications

• Free wheeling diodes in converters and motor control circuits
• Rectifiers in switch mode power supplies (SMPS)
• Antiparallel diodes for high frequency switching devices

Diode Arrays Procurement Notes

Verify the specific suffix '03A' against official IXYS documentation to confirm the 300 V rating. Ensure the SOT-227 package dimensions match the required panel mounting constraints. Confirm that the 12.5 A peak reverse current specification aligns with the thermal management design for the intended operating environment.

Diode Arrays Selection Notes

Select this component when low switching loss and soft recovery are critical for efficiency. The 30 A current rating suits moderate power applications. Verify compatibility with high-frequency switching requirements compared to standard fast recovery alternatives. Consider the planar passivation for reliability in harsh electrical environments.

Diode Arrays Part Context

This part belongs to the DSEP2x31 series from IXYS, designed as international standard miniBLOC packages. It integrates two independent Fast Recovery Epitaxial Diodes (FRED) into a single unit. The series emphasizes high performance through reduced parasitic inductance and optimized thermal dissipation for industrial power electronics.

Diode Arrays Replacement Considerations

Consult official IXYS datasheets for direct cross-reference models within the DSEP2x31 family. Verify pinout compatibility and thermal resistance values before substituting with other manufacturers' fast recovery diodes.
