DPG120C300QB

Diode Arrays Overview

The IXYS DPG120C300QB is a HiPerFRED2 series dual switching diode designed for high-power applications. It features a 300V peak reverse voltage and supports a continuous forward current of 60A per leg, with a total average rectified current of 120A. The device exhibits a fast recovery time of 35ns and a low forward voltage drop of 1.63V at rated conditions. Packaged in a TO-3P-3 through-hole case, it handles a surge current of 720A and dissipates up to 320W of power. Operating temperatures range from -55°C to +150°C junction temperature.

Diode Arrays Feature Summary

• Dual configuration providing two independent switching paths within a single package
• HiPerFRED2 technology ensuring fast recovery characteristics and low switching losses
• High thermal performance capability supporting significant power dissipation

Diode Arrays Applications

• High-frequency inverters and motor drives
• Uninterruptible power supplies (UPS)
• Induction heating systems

Diode Arrays Procurement Notes

Verify the specific suffix 'QB' against the manufacturer's latest datasheet to confirm pinout and mechanical dimensions match your design requirements. Ensure thermal interface materials are compatible with the TO-3P-3 package base plate for optimal heat transfer. Confirm RoHS compliance status if required by your assembly specifications.

Diode Arrays Selection Notes

Select this component when high current capacity and fast switching speeds are critical. Compare the 120A total rating against load requirements to ensure adequate margin. Consider the TO-3P-3 package size for PCB layout constraints and heatsinking capabilities relative to lower-current alternatives in the same series.

Diode Arrays Part Context

This part belongs to the IXYS HiPerFRED2 family of ultra-fast recovery diodes. It complements other devices like the DPG60C300QB and DPG30C400HB, offering higher current handling than smaller variants while maintaining similar voltage ratings and recovery speeds within the same product line.

Diode Arrays Replacement Considerations

Check for direct cross-references or updated part numbers from IXYS or Vishay. Verify that any substitute maintains the 300V rating, 35ns recovery time, and TO-3P-3 footprint to ensure mechanical and electrical compatibility without redesign.
