Overview
The AR3PGHM3/86A is a fast recovery rectifier diode manufactured by Vishay Semiconductors. It features a single cathode dual anode configuration housed in a TO-277A-3 surface-mount package. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward current of 3 A. Key electrical parameters include a forward voltage of 1.04 V, a reverse current of 330 nA, and a maximum surge current of 50 A. The component exhibits a recovery time of 122 ns and operates within a temperature range of -55 C to +175 C.
Feature Summary
- Fast recovery performance with low leakage current for efficient switching applications
- Avalanche rated capability for robust operation under transient conditions
- Single cathode dual anode configuration enabling common ground circuit designs
Applications
- High-frequency power supply circuits
- Free-wheeling diode applications in motor drives
- DC-DC converter output rectification
Procurement Notes
Verify the specific suffix /86A against official Vishay documentation to confirm packaging details such as reel size or tape specifications. Ensure the ordering part number matches the required voltage and current ratings for your design. Cross-reference the RoHS compliance status and automotive qualification (AEC-Q101) if applicable to your project requirements before finalizing procurement.
Selection Notes
Select this component when a 3 A fast recovery diode with 400 V blocking capability is required in a compact SMD form factor. The TO-277A-3 package offers thermal efficiency suitable for space-constrained PCB layouts. Consider the 122 ns recovery time for high-frequency switching applications where minimizing reverse recovery charge is critical for system efficiency.
Part Context
This part belongs to the AR3P series of fast recovery rectifiers from Vishay. The series utilizes advanced silicon planar technology to achieve high reliability and consistent performance. The AR3PG variant specifically denotes avalanche-rated devices designed for inductive load switching environments, providing enhanced ruggedness compared to standard rectifiers in the same package family.
Replacement Considerations
Consult Vishay datasheets for direct pin-compatible alternatives within the AR3P series that match the 400 V and 3 A specifications. Verify that any substitute maintains the TO-277A-3 footprint and meets the same thermal and electrical performance criteria.
