AS1PJ-M3/85A

Overview

The AS1PJ-M3/85A is a standard avalanche surface mount rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 1.5 A. The device operates within a junction temperature range of -55 °C to +175 °C and supports a non-repetitive avalanche energy of 20 mJ at IAS = 1.0 A. Packaged in the SMP (DO-220AA) form factor, it exhibits a typical instantaneous forward voltage of 0.95 V at IF = 1.0 A and a reverse current of 0.3 μA at rated VR.

Feature Summary

• Glass passivated pellet chip junction construction
• Controlled avalanche characteristics for rugged operation
• Very low profile design suitable for automated placement
• AEC-Q101 qualified for automotive reliability

Applications

• General purpose rectification of power supplies
• Inverter and converter circuits
• Freewheeling diodes for consumer electronics
• Automotive electronic systems
• Telecommunication equipment

Procurement Notes

Verify that the ordering suffix /85A corresponds to the 10,000-unit reel configuration on a 13-inch diameter plastic tape. Confirm compliance with RoHS directives and halogen-free material requirements. Ensure the specific M3 suffix variant meets JESD 201 class 1A whisker test standards for your assembly process.

Selection Notes

Select this component when a 600 V blocking capability is required alongside a 1.5 A continuous current rating. The controlled avalanche characteristic makes it suitable for applications where inductive kickback or transient overvoltages may occur. Verify thermal management requirements against the specified junction-to-ambient thermal resistance values.

Part Context

This part belongs to the eSMP series of standard avalanche rectifiers from Vishay. It shares the SMP (DO-220AA) package footprint with other variants in the AS1P family, which differ primarily in their reverse voltage ratings ranging from 200 V to 1000 V. The series is designed for high-reliability surface mount applications.

Replacement Considerations

Direct substitutes include AS1PG-M3/85A (400 V), AS1PK-M3/85A (800 V), and AS1PM-M3/85A (1000 V). These parts share identical current ratings, package dimensions, and thermal characteristics, differing only in their maximum repetitive peak reverse voltage specifications.
