Overview
The AS1FMHM3/I is a standard avalanche surface-mount rectifier from Vishay, rated for a maximum repetitive peak reverse voltage of 1000 V and an average forward current of 1.5 A. It features a peak forward surge current capability of 30 A and operates within a junction temperature range of -55 °C to +175 °C. The device utilizes a glass passivated pellet chip junction and is housed in the SMF (DO-219AB) package. It meets MSL level 1 requirements and supports wave and reflow soldering processes.
Feature Summary
- AEC-Q101 qualified for automotive applications
- Glass passivated pellet chip junction
- Compatible with SOD-123W package case outline
Applications
- General purpose rectification of power supplies
- Inverters and converters
- Freewheeling diodes for consumer, automotive, and telecommunication equipment
Procurement Notes
Verify that the ordering suffix /I corresponds to the 13-inch diameter plastic tape and reel packaging configuration as specified in the datasheet. Confirm the HM3 designation indicates halogen-free, RoHS-compliant automotive grade material categorization. Ensure compatibility with automated placement systems and required soldering profiles before procurement.
Selection Notes
Select this component when a 1000 V rating is required for high-voltage rectification tasks. The avalanche capability allows for energy absorption up to 20 mJ at 1.0 A. Consider the SMF package dimensions for space-constrained PCB layouts. Verify thermal resistance parameters against the specific mounting pad area and ambient conditions of the target application.
Part Context
This part belongs to the eSMP series of standard avalanche surface-mount rectifiers. It shares the SMF (DO-219AB) mechanical footprint with other variants in the AS1FD, AS1FG, AS1FJ, and AS1FK families, differentiated primarily by their voltage ratings. The HM3 suffix specifically denotes the automotive-grade qualification and material compliance distinct from commercial grades.
