Overview
The AS3PJ-M3/87A is a high current density standard avalanche surface-mount rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction and operates within a temperature range of -55 to +175 °C. The device provides a maximum repetitive peak reverse voltage of 600 V, an average forward current of 3.0 A, and a peak forward surge current of 70 A. It exhibits a typical instantaneous forward voltage of 0.92 V at 1.5 A and a typical reverse recovery time of 1.2 μs. Packaged in the SMPC (TO-277A) form factor with a typical height of 1.1 mm, it supports automated placement.
Feature Summary
- Glass passivated pellet chip junction for reliability
- Controlled avalanche characteristics for energy handling
- Low leakage current performance
- High forward surge capability
Applications
- General purpose rectification of power supplies
- Inverters and converters
- Freewheeling diodes for consumer electronics
- Automotive applications
- Telecommunication equipment
Procurement Notes
Verify the specific ordering code against the datasheet to ensure correct package quantity and revision. Confirm that the M3 suffix meets JESD 201 class 1A whisker test requirements if applicable. Check for halogen-free and RoHS compliance status as indicated by the base part number designation. Ensure the delivery mode matches the required reel diameter specifications.
Selection Notes
Select this component when a low-profile surface-mount rectifier with controlled avalanche characteristics is required. The SMPC package is suitable for automated placement processes. Consider the thermal resistance values and derating curves for high-temperature environments. Verify that the 600 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.
Part Context
This component belongs to the eSMP series of high current density standard avalanche surface-mount rectifiers. The series includes variants with different reverse voltage ratings such as AS3PD, AS3PG, AS3PK, and AS3PM. All share the same physical package and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage capabilities.
Replacement Considerations
Compatible substitutes include other Vishay AS3P series parts like AS3PG or AS3PK, provided the reverse voltage ratings meet the application needs. Ensure any replacement maintains the SMPC (TO-277A) package dimensions and pinout configuration for direct board compatibility.
