Overview
The AS1FJHM3/I is a surface-mount avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 600 V and an average rectified current rating of 1.5 A. The device utilizes the FRED Pt® technology, offering a fast recovery time of less than or equal to 500 ns with forward currents greater than 200 mA. It operates within a junction temperature range of -55°C to 175°C and is housed in a DO-219AB (SMF) package.
Feature Summary
- Avalanche-rated construction for robust transient protection
- Fast recovery characteristics suitable for high-frequency applications
- Extended operating temperature range up to 175°C
Applications
- High voltage protection circuits
- Surface mount rectification
- Automotive electronics systems
Procurement Notes
Verify the specific suffix 'I' against official Vishay documentation to confirm exact binning or tape-and-reel specifications, as suffixes often denote packaging variations rather than functional changes. Ensure the component meets RoHS compliance requirements if mandated by your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a surface-mount avalanche diode with 600 V blocking capability and 1.5 A continuous current handling is required. The DO-219AB package offers a compact footprint for space-constrained designs. Consider the fast recovery time for efficiency in switching applications. Verify thermal management needs given the 175°C junction limit and ensure the application voltage does not exceed the rated DC reverse voltage.
Part Context
This component belongs to Vishay's general-purpose diode portfolio, specifically designed for surface-mount technology. It is part of a series that includes variants like the AS1FJHM3/H, differing primarily in packaging or minor electrical tolerances. The device serves as a reliable solution for rectification and protection in modern electronic assemblies requiring small form factors and high reliability.
Replacement Considerations
The AS1FJHM3/H is a confirmed substitute part number with identical electrical ratings and package type. Verify pinout compatibility and ensure the replacement variant meets the same automotive qualification standards if applicable.
