Overview
The AS3PKHM3/86A is a standard recovery rectifier manufactured by Vishay Semiconductors. It features a dual anode configuration housed in a TO-277A-3 surface-mount package. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward current of 3 A. Key electrical parameters include a forward voltage of 900 mV, a maximum surge current of 70 A, and a reverse current of 280 nA. It operates within a temperature range of -55 C to +175 C.
Feature Summary
- Dual anode configuration for flexible circuit integration
- High thermal stability with extended operating temperature range
- Surface-mount design optimized for automated assembly
Applications
- General-purpose power supply rectification
- DC-DC converter output stages
- Industrial control system power modules
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TO-277A-3 package. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when a dual anode topology is required within a compact surface-mount form factor. The 800 V rating suits high-voltage DC applications, while the 3 A current capacity supports moderate power loads. Consider the standard recovery characteristics for general switching frequencies rather than high-speed applications.
Part Context
This part belongs to the AS3P series from Vishay Semiconductors, designed for robust rectification in space-constrained environments. The eSMP branding indicates its placement within Vishay's enhanced small-outline package lineup, offering improved thermal performance compared to traditional leaded packages.
Replacement Considerations
Check for direct substitutes such as the VS-6ESU06HM3/86A or VS-6ESH02HM3/86A if higher current or faster recovery is needed, though pinouts and ratings differ significantly.
