SURS340DT3G Description

Short technical summary and product information.

The SURS340DT3G is an ultrafast power rectifier from On Semiconductor, designed for high voltage, high frequency applications. It offers a peak repetitive reverse voltage of 400V and an average rectified forward current of 3.0A at TL=130°C, with a low forward voltage drop of 1.05V maximum at 3A and junction temperature 150°C. The reverse recovery time is 75ns, making it suitable for switching power supplies and freewheeling circuits.

 

The device is housed in a compact, surface mount DO-214AB (SMC) package with J-bend leads for automated handling. It operates over a temperature range of -65°C to 175°C and is rated MSL1 for moisture sensitivity. Additional features include ESD robustness (Human Body Model >8kV, Machine Model >400V), UL 94 V-0 flammability rating, and lead-free construction.

 

The SURS340DT3G is AEC-Q101 qualified, supporting automotive and other applications requiring stringent quality and reliability standards. The package is supplied on 16mm tape and reel in quantities of 2500 units per reel.
