Overview
The AU2PK-M3/86A is a fast recovery rectifier manufactured by Vishay Semiconductors. It features a single cathode dual anode configuration housed in an SMPC (TO-277A-3) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward current of 2 A. Key electrical parameters include a forward voltage of 2.1 V, a reverse current of 270 nA, and a maximum surge current of 30 A. The component operates within a temperature range of -55 C to +175 C and exhibits a recovery time of 50 ns.
Feature Summary
- Utilizes eSMP packaging technology for compact surface-mount integration
- Designed for high-speed switching applications with ultrafast recovery characteristics
- Capable of withstanding high thermal stress up to 175 C junction temperature
Applications
- High-frequency power supply circuits
- DC-DC converter topologies
- Free-wheeling diode implementations in motor drives
Procurement Notes
Verify the specific suffix /86A against official datasheets to confirm reel packaging specifications. Ensure compatibility with RoHS directives as indicated in manufacturer documentation. Cross-reference the Mouser part number 625-AU2PK-M3/86A for accurate sourcing channels. Confirm that the SMPC package dimensions align with PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when high voltage blocking capability and fast recovery are required in a small footprint. The dual anode configuration allows for common cathode arrangements in bridge or synchronous rectification setups. Consider the 800 V rating for mains-derived applications. Evaluate thermal management needs given the 2 A continuous current rating in the TO-277A-3 package.
Part Context
This part belongs to the AU2P series of ultrafast recovery rectifiers from Vishay. It is designed to replace through-hole components in modern surface-mount assembly lines. The eSMP branding indicates optimized thermal performance and reliability standards suitable for industrial and consumer electronics. It serves as a direct pin-compatible alternative to larger legacy packages while maintaining similar electrical ratings.
Replacement Considerations
Check for AU2PM-M3/86A if 1000 V rating is required instead of 800 V. Verify S4PK-M3/86A for higher current capacity at 4 A. Ensure substitute parts maintain the same SMPC package and pinout configuration.
