Overview
The AS3PJHM3/86A is a high current density standard avalanche surface-mount rectifier from Vishay General Semiconductor. It features a single diode configuration in an SMPC (TO-277A) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 600 V and a maximum DC forward current of 3.0 A. The device supports a peak forward surge current of 70 A and has a typical junction-to-ambient thermal resistance of 80 °C/W. It operates within a temperature range of -55 °C to +175 °C.
Feature Summary
- Controlled avalanche characteristics for robust performance under transient conditions
- Glass passivated pellet chip junction ensuring reliability
- Very low profile design suitable for automated placement processes
- Compliant with automotive qualification standards
Applications
- General purpose rectification in power supplies
- Freewheeling diodes in inverters and converters
- Automotive electronic systems
- Telecommunication equipment
Procurement Notes
Verify the specific ordering code suffix to confirm the packaging type and revision level. Ensure the HM3 designation is selected when AEC-Q101 automotive qualification is required. Confirm compliance with halogen-free and RoHS directives based on the base part number M3 suffix. Check the delivery mode specifications for tape and reel dimensions prior to procurement.
Selection Notes
Select this component for applications requiring high current density in a compact surface-mount form factor. The controlled avalanche capability makes it suitable for circuits prone to inductive kickback. Verify that the 600 V reverse voltage rating meets the circuit's peak inverse voltage requirements. Consider the thermal resistance values when designing heat dissipation strategies for the PCB layout.
Part Context
This device belongs to the eSMP Series K, which includes variants with different voltage ratings such as AS3PD, AS3PG, AS3PK, and AS3PM. All variants share the same physical package and general feature set but differ in their maximum repetitive peak reverse voltage capabilities ranging from 200 V to 1000 V.
Replacement Considerations
Direct substitutes within the same series include AS3PDHM3/86A (200 V), AS3PGHM3/86A (400 V), AS3PKHM3/86A (800 V), and AS3PMHM3/86A (1000 V). Ensure the replacement part matches the required voltage rating and maintains the same package footprint.
