Overview
The AU1FG-M3/I is a single ultrafast recovery rectifier from Vishay Semiconductors, housed in the DO-219AB (SMF) surface-mount package. It features a 400 V repetitive peak reverse voltage and a 1 A average forward current rating. The device exhibits a maximum forward voltage of 1.5 V and a typical reverse leakage current of 1 uA. Its ultrafast recovery time is specified at 75 ns, with a maximum surge current capability of 30 A. Operating temperatures range from -55 C to +175 C.
Feature Summary
- Ultrafast recovery characteristics for high-speed switching applications
- Avalanche rated construction for robustness against transient energy
- Surface-mount SMF package design for automated assembly
Applications
- High-frequency power supply circuits
- Freewheeling diode protection in inductive loads
- Snubber circuits in switching regulators
Procurement Notes
Verify the specific suffix /I against official Vishay documentation to confirm tape-and-reel packaging quantities and handling specifications. Ensure the component meets RoHS and REACH compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when circuit designs require fast reverse recovery times combined with avalanche ruggedness in a compact footprint. The 400 V rating suits medium-voltage DC bus applications. Compare the 75 ns recovery time against standard rectifiers to ensure compatibility with high-frequency switching topologies requiring minimal reverse recovery charge losses.
Part Context
This device belongs to Vishay's AU1F series of ultrafast recovery rectifiers designed for general-purpose high-efficiency applications. The SMF package provides a small outline footprint suitable for dense PCB layouts. The M3 suffix indicates lead-free termination plating compliant with international environmental standards.
Replacement Considerations
Official substitutes include AU1FM-M3/H and AU1FJ-M3/I from the same manufacturer family. Verify pinout compatibility and thermal performance characteristics before implementing any cross-brand replacements.
