Overview
The AS4PK-M3/86A is an Avalanche Rectifier from Vishay, rated at 800 V reverse voltage and 2.4 A average forward current. It utilizes the eSMP package (TO-277A) for surface mount installation. The device features a single cathode/dual anode configuration and operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Engineered with avalanche capability for robust operation in inductive switching environments
- Utilizes eSMP surface mount packaging for compact board space efficiency
- Features dual anode configuration for flexible circuit integration
Applications
- High-voltage power supply circuits requiring avalanche ruggedness
- Inductive load protection applications
- General purpose rectification in space-constrained designs
Procurement Notes
Verify the specific suffix /86A against the official datasheet to confirm reel quantity and tape specifications. Ensure the ordering part number matches the exact electrical ratings required for the target application. Cross-reference the manufacturer's latest documentation for any potential changes in pinout or thermal characteristics before finalizing procurement.
Selection Notes
Select this component when high voltage blocking capability combined with avalanche energy rating is necessary. The TO-277A package offers a balance between current handling and footprint size. Consider the dual anode topology if common cathode configurations are preferred in the schematic design. Verify thermal management requirements align with the package's dissipation capabilities.
Part Context
This part belongs to Vishay's eSMP series of rectifiers, designed for modern surface mount assembly processes. The series provides alternatives to traditional through-hole packages while maintaining comparable electrical performance. The AS4PK variant specifically addresses applications needing higher voltage ratings within the same physical form factor family.
Replacement Considerations
Compatible substitutes include other Vishay eSMP avalanche rectifiers such as the AS4PM-M3/86A or AS4PG-M3/86A, provided their voltage ratings meet the system requirements. Verify pin compatibility and thermal resistance values when substituting.
