Overview
The AS1PJHM3/85A is a standard avalanche surface mount rectifier from Vishay, part of the eSMP series. It features a glass passivated pellet chip junction in an SMP (DO-220AA) package. The device has a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 1.5 A. Key electrical parameters include a typical instantaneous forward voltage of 0.99 V at 1.5 A, a reverse current of 0.3 μA at rated VR, and a typical reverse recovery time of 1.5 μs. It supports non-repetitive avalanche energy of 20 mJ and operates within a junction temperature range of -55 to +175 °C.
Feature Summary
- Controlled avalanche characteristics for robust operation
- Glass passivated pellet chip junction construction
- Low forward voltage drop and low leakage current
- Automotive grade qualification per AEC-Q101
Applications
- General purpose rectification of power supplies
- Inverter and converter circuits
- Freewheeling diodes for consumer electronics
- Automotive electronic systems
- Telecommunication equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging quantity and delivery mode. The /85A suffix indicates a 10,000-unit reel configuration. Confirm that the HM3 designation aligns with automotive grade requirements and halogen-free compliance standards before finalizing procurement specifications.
Selection Notes
Select this component when a 600 V blocking capability and 1.5 A continuous current are required in a compact SMP footprint. The controlled avalanche rating allows for use in inductive load switching applications without external protection. Ensure thermal management accounts for the specified junction-to-ambient resistance values under expected operating conditions.
Part Context
This component belongs to the Vishay eSMP series of standard avalanche rectifiers. The series includes variants with different voltage ratings such as AS1PD, AS1PG, AS1PK, and AS1PM. All share the same physical SMP package and general electrical profile, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 200 V to 1000 V.
Replacement Considerations
Direct substitutes within the same family include AS1PJ-M3/84A for alternative packaging or AS1PJHM3/84A for automotive grade in smaller reels. Cross-brand replacements must match the 600 V rating, 1.5 A current capacity, and DO-220AA mechanical outline.
