Overview
The AS1FD-M3/I is a surface-mount Avalanche Diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current rating of 1.5 A. The component utilizes the DO-219AB (SMF) package and is designed for operation within a junction temperature range of -55°C to 175°C.
Feature Summary
- Engineered with avalanche characteristics for robust energy handling capabilities
- Utilizes a compact surface-mount DO-219AB (SMF) package design
- Supports extended high-temperature operation up to 175°C junction temperature
Applications
- Transient voltage suppression in electronic circuits
- Protection against inductive load switching spikes
- General-purpose clamping applications requiring avalanche ruggedness
Procurement Notes
Verify the specific suffix designation, as 'I' may indicate regional or packaging variations distinct from the standard 'H' version. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors prior to procurement to ensure alignment with project requirements.
Selection Notes
Select this component when circuit protection requires a surface-mount solution capable of handling avalanche energy at 200 V reverse voltage. Ensure the application demands a 1.5 A current rating and operates within the specified -55°C to 175°C temperature range. Validate that the DO-219AB footprint matches the PCB layout constraints.
Part Context
This device belongs to Vishay's general-purpose diode portfolio, specifically categorized under Avalanche Diodes. It serves as a surface-mount alternative to through-hole variants, offering similar electrical performance in a smaller form factor suitable for modern automated assembly processes and space-constrained designs.
Replacement Considerations
The AS1FD-M3/H is a confirmed substitute part number with identical electrical ratings and package type. Verify pinout compatibility and thermal characteristics before substitution.
