Overview
The AU2PGHM3/86A is a surface-mount avalanche-rated diode from Vishay, housed in a TO-277A (SMPC) package. It features a maximum repetitive reverse voltage of 400 V and an average forward current rating of 1.6 A. The device utilizes oxide planar chip junction technology for robust performance. Key electrical characteristics include a typical forward voltage drop at rated current and ultrafast recovery times suitable for high-frequency applications. It operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Avalanche-rated construction for enhanced ruggedness
- Ultrafast recovery characteristics for high-frequency switching
- Oxide planar chip junction technology
- Low profile design ideal for automated placement
Applications
- High-frequency rectification circuits
- Flyback diode protection in inductive loads

Procurement Notes
Verify the specific suffix /86A corresponds to the required reel packaging configuration. Confirm RoHS compliance status and AEC-Q101 qualification requirements against the project specifications. Ensure the TO-277A footprint matches the PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when avalanche energy handling capability is required alongside standard rectification functions. The TO-277A package offers a compact form factor compared to through-hole alternatives. Consider the 400V rating and 1.6A current capacity relative to the circuit's peak inverse voltage and load current demands.
Part Context
This part belongs to the AU2P series of ultrafast rectifiers manufactured by Vishay General Semiconductor. The series is designed for high-efficiency power conversion applications. The AU2PG variant specifically denotes the avalanche-rated version within this lineup, providing additional durability in hard-switching environments.
Replacement Considerations
Direct substitutes may include other Vishay avalanche diodes in the TO-277A package with matching 400V and 1.6A ratings. Verify pinout compatibility and thermal characteristics when considering cross-brand replacements.
