DSEI2X101-12P

Diode Arrays Overview

The IXYS DSEI2X101-12P is a dual parallel fast recovery epitaxial diode (FRED) module designed for high-power applications. It features two independent chips within a single package, providing a total continuous forward current of 182 A (91 A per chip). The device supports a peak repetitive reverse voltage of 1200 V and exhibits a maximum forward voltage drop of 1.87 V. Key electrical characteristics include a peak non-repetitive forward surge current of 900 A and a typical reverse recovery time of 60 ns. The component utilizes an isolated configuration with a 3000 V isolation voltage rating.

Diode Arrays Feature Summary

• Dual parallel configuration integrating two independent FRED chips in one package
• High isolation voltage rating of 3000 V for enhanced safety
• Soft recovery behavior to minimize switching losses and electromagnetic interference
• Planar passivated chips ensuring robust performance under thermal stress

Diode Arrays Applications

• Free wheeling diodes in converters and motor control circuits
• Rectifiers in switch mode power supplies (SMPS)

• Snubber diodes in high voltage circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'P' against official datasheets to confirm pinout and mounting style differences from the 'A' variant. Ensure compatibility with SOT-227B or equivalent screw-mount heatsinking solutions. Confirm RoHS compliance status through the manufacturer's latest documentation before integration into regulated equipment designs.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling and fast switching speeds. The dual parallel structure allows for efficient current sharing and reduced thermal resistance compared to single diode solutions. Consider the 1200 V rating for medium-voltage industrial systems. Evaluate thermal management requirements given the 250 W power dissipation capability and ensure adequate heatsinking for sustained operation at full load.

Diode Arrays Part Context

This part belongs to the DSEI2X101 series of Fast Recovery Epitaxial Diodes manufactured by IXYS. The series is engineered for efficiency and reliability in power conversion systems. The DSEI2X101-12P specifically denotes the 1200 V voltage class version within this family, offering a balance between high current capacity and rapid recovery characteristics suitable for demanding power electronics environments.

Diode Arrays Replacement Considerations

Direct substitutes may include other IXYS models within the DSEI2X101 series with compatible voltage ratings, such as DSEI2X101-12A, provided pinout and mechanical dimensions match. Cross-brand replacements require careful verification of forward current, reverse voltage, and recovery time specifications to ensure circuit integrity.
