Overview
The AS1FGHM3/I is a 400 V, 1.5 A Avalanche-rated Zener diode from Vishay General Semiconductor - Diodes Division. It utilizes the TransZorb technology and is housed in a DO-219AB (SMF) surface-mount package. The device operates within a junction temperature range of -55°C to 175°C. It features a typical reverse standoff voltage of 46.8 V and a minimum breakdown voltage of 53.2 V. The component is designed for robust transient protection applications.
Feature Summary
- Avalanche-rated construction for enhanced ruggedness
- TransZorb technology for high-energy surge handling
- Surface-mount DO-219AB (SMF) packaging
Applications
- Transient voltage suppression in electronic circuits
- Protection of sensitive semiconductor devices against ESD and lightning-induced surges
- General-purpose clamping in power supply lines
Procurement Notes
Verify the specific suffix 'I' against official Vishay documentation to confirm tape-and-reel configuration or specific binning requirements. Ensure the DO-219AB footprint matches the design layout. Confirm RoHS compliance status with the manufacturer's current datasheet before finalizing procurement specifications.
Selection Notes
Select this component when avalanche capability is required for Zener applications. The 400 V rating suits medium-voltage transient protection needs. The SMF package offers space efficiency for surface-mount designs. Verify that the peak pulse current and power dissipation ratings meet the specific circuit's energy absorption requirements.
Part Context
This part belongs to Vishay's TransZorb family of TVS diodes. These components are engineered for high reliability and fast response times. The AS1FGHM3 series provides bidirectional or unidirectional protection options in compact packages suitable for modern electronics manufacturing processes.
Replacement Considerations
Check for direct substitutes such as AS1FGHM3/H if reel specifications differ. Verify equivalent voltage ratings and package dimensions for cross-reference.
