VS-HFA180NH40PBF

Single Diodes Overview

The VS-HFA180NH40PbF is a HEXFRED ultrafast soft recovery diode rated for 400 V reverse voltage and 180 A average forward current. It utilizes the HALF-PAK (D-67) lug terminal package with an isolated cathode base. The device features low reverse recovery charge and time, optimized for high-frequency power conditioning systems to reduce switching losses and EMI/RFI.

Single Diodes Feature Summary

• Ultrafast soft recovery characteristics designed to minimize electromagnetic interference and eliminate snubber requirements in most applications.
• Optimized for high-frequency power conditioning systems to significantly reduce switching losses and overall system heat generation.
• Industrial level qualification ensuring reliability under demanding operating conditions.

Single Diodes Applications

• High-frequency power converters
• Motor drives
• Power conditioning systems

Single Diodes Procurement Notes

Verify the specific suffix 'PbF' confirms lead-free compliance and industrial qualification status. Confirm that the HALF-PAK (D-67) mounting dimensions align with the heatsink interface. Validate thermal resistance parameters against the maximum allowable case temperature curves provided in the datasheet for the intended duty cycle.

Single Diodes Selection Notes

Select this component when high average current handling at 180 A is required alongside fast switching speeds. The 400 V rating suits medium-voltage applications. Ensure the design accommodates the HALF-PAK mechanical footprint and lug terminal torque specifications of 3 to 4 N·m for secure mounting.

Single Diodes Part Context

This part belongs to the Vishay HEXFRED family of electron-irradiated diodes. The 'N' designation indicates a non-isolated configuration within the die structure, while the 'H' denotes the HALF-PAK physical package style. It serves as a high-performance alternative to standard recovery diodes in efficiency-critical designs.

Single Diodes Replacement Considerations

No public confirmed substitute part numbers are available in the source material.
