Overview
The AU1FD-M3/H is a single ultra-fast recovery rectifier manufactured by Vishay Semiconductors. It features a reverse voltage rating of 200 V and an average forward current of 1 A. The device utilizes the DO-219AB-2 (SMF) surface-mount package. Key electrical parameters include a maximum forward voltage of 1.5 V, a peak surge current capability of 30 A, and a reverse leakage current of 1 uA. The component exhibits an ultra-fast recovery time of 75 ns. It operates within a temperature range from -55 C to +175 C.
Feature Summary
- Ultra-fast recovery characteristics for high-speed switching applications
- Avalanche rated for robust operation in inductive load environments
- Surface-mount construction in a compact SMF package
Applications
- High-frequency power supply circuits
- Free-wheeling diode applications in inductive loads
- DC-DC converter output rectification
Procurement Notes
Verify the specific ordering suffix and tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the component matches the required thermal and electrical specifications for the target design environment.
Selection Notes
Select this component for designs requiring fast switching speeds and avalanche ruggedness in a small footprint. Compare the 75 ns recovery time against system switching frequencies to ensure minimal reverse recovery losses. Evaluate the 1.5 V forward voltage drop for efficiency requirements at the intended operating current levels.
Part Context
This part belongs to Vishay's AU1FD series of surface-mount ultra-fast recovery rectifiers. The series is designed to replace bulkier through-hole alternatives in modern electronics. It provides a balance of speed and reliability for compact power management solutions.
Replacement Considerations
Direct substitutes may include other 1 A, 200 V ultra-fast rectifiers in the SMF package with comparable recovery times. Verify pinout compatibility and thermal resistance values before substitution.
