Overview
The AS1FJ-M3/I is a single avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 600 V and an average forward rectified current (Io) of 1.5 A. The device utilizes the eSMP surface-mount technology in a DO-219AB (SMF) package. Key electrical parameters include a forward voltage (Vf) of 990 mV at 1.5 A, a maximum surge current of 30 A, and a reverse leakage current of 140 nA at 600 V. The junction temperature range spans from -55°C to +175°C.
Feature Summary
- Incorporates avalanche ruggedness for enhanced reliability under transient conditions
- Utilizes eSMP surface-mount technology for compact board integration
- Supports high junction operating temperatures up to 175°C
Applications
- General-purpose rectification in surface-mount power supplies
- Protection circuits requiring avalanche capability
- High-temperature electronic assemblies
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with automated placement equipment for the DO-219AB form factor. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount solution with avalanche rating is required for 600 V applications. The 1.5 A current rating suits moderate power levels where space constraints favor the SMF package over through-hole alternatives. Evaluate thermal management needs given the 175°C junction limit.
Part Context
This part belongs to Vishay's eSMP series of surface-mount rectifiers. The AS1FJ variant specifically denotes avalanche-rated devices designed for robust performance. The M3 suffix indicates lead-free construction compliant with EU directives. The I suffix typically denotes tape-and-reel packaging for high-volume manufacturing.
FAQ
