MURS340-M3/9AT Description

Short technical summary and product information.

The Vishay MURS340-M3/9AT is a surface-mount ultrafast plastic rectifier designed for high-frequency rectification and freewheeling applications. This device features a glass passivated pellet chip junction and comes in a standard DO-214AB (SMC) package.

 

Key electrical characteristics include an average rectified current of 3.0 A, a repetitive peak reverse voltage of 400 V, and a typical forward voltage of 1.05 V at 3 A (maximum 1.28 V). The reverse recovery time is 50 ns, enabling low switching losses in high-speed switching mode converters. The non-repetitive peak forward surge current is rated at 125 A (8.3 ms half-sine).

 

The device operates over a junction temperature range of -65°C to 175°C. It is RoHS-compliant (E3 suffix) and meets MSL level 1 per J-STD-020. The package is surface-mount DO-214AB (SMC), with matte tin plated terminals and polarity indicated by a cathode band. It is suitable for automated placement and used in consumer, computer, automotive, and telecommunication power supplies.
