MURS340-E3/57T Description

Short technical summary and product information.

The MURS340-E3/57T is a surface-mount ultrafast plastic rectifier from Vishay General Semiconductor, designed for high frequency rectification and freewheeling applications in switching mode converters and inverters. It utilizes a glass passivated pellet chip junction for reliability and automated placement.

 

Key electrical specifications include a repetitive peak reverse voltage (VRRM) of 400V, an average rectified current (IF(AV)) of 3A at TL=130°C (4A at TL=115°C), and a forward voltage (VF) of 1.05V maximum at 3A. The device offers an ultrafast reverse recovery time (trr) of 50ns maximum, enabling low switching losses. The maximum forward surge current (IFSM) is 125A for an 8.3ms half sine-wave.

 

The part is housed in a DO-214AB (SMC) package with matte tin plated terminals, color band cathode polarity marking, and is RoHS-compliant (E3 suffix). It meets MSL level 1 per J-STD-020 with a peak reflow temperature of 260°C. The operating junction temperature range extends from -65°C to +175°C.
