DPG60C400QB

Diode Arrays Overview

The IXYS DPG60C400QB is a high-performance fast recovery diode from the HiPerFRED2 series, designed for low loss and soft recovery applications. It features a common cathode dual configuration housed in a TO-3P-3 package. Key electrical parameters include a peak reverse voltage of 400 V, an average forward current of 30 A per diode, and a maximum surge current of 360 A. The device exhibits a typical reverse recovery time of 35 ns and a forward voltage of 1.63 V at rated conditions. It supports a maximum power dissipation of 160 W and operates within a junction temperature range of -55°C to +150°C.

Diode Arrays Feature Summary

• Soft reverse recovery behavior minimizes electromagnetic interference (EMI) and radio frequency interference (RFI).
• Planar passivated chips ensure reliable operation with avalanche voltage rating.
• Very low leakage current and Irm values reduce power dissipation and turn-on losses.

Diode Arrays Applications

• Antiparallel diodes for high-frequency switching devices
• Free-wheeling diodes in inductive load circuits
• Snubber diodes for voltage spike suppression
• Rectifiers in switch-mode power supplies (SMPS)
• Uninterruptible power supplies (UPS)

Diode Arrays Procurement Notes

Verify the specific suffix 'QB' against the manufacturer's official datasheet to confirm pinout and thermal characteristics, as suffixes often denote packaging or specific testing criteria. Ensure the component source provides valid traceability documentation. Cross-reference the part number with the latest IXYS product change notices to confirm manufacturing status and compliance with current environmental regulations before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when designing circuits requiring fast switching speeds with minimal reverse recovery charge to improve efficiency. The common cathode dual configuration allows for compact half-bridge or full-wave rectifier topologies. Evaluate the thermal management requirements based on the 160 W power dissipation rating and the TO-3P-3 package's thermal resistance. Compare the 35 ns recovery time against system switching frequencies to ensure adequate performance margins.

Diode Arrays Part Context

This diode belongs to the IXYS HiPerFRED2 family, which specializes in high-voltage, high-current fast recovery rectifiers. The DPG60C400QB shares architectural similarities with other DPG series parts but is distinguished by its 400 V blocking capability and dual common cathode arrangement. It serves as a critical passive component in power electronics systems demanding high reliability and low switching losses.

Diode Arrays Replacement Considerations

Potential substitutes within the same family include DPG60C400HB, which offers identical electrical specifications but utilizes a TO-247AD-3 package. Verify mechanical footprint compatibility and thermal interface requirements when considering alternative packages from the same manufacturer or other vendors offering equivalent 400V 30A dual fast recovery diodes.
