1.5SMC39A-E3/57T Description

Short technical summary and product information.

The 1.5SMC39A-E3/57T is a unidirectional transient voltage suppressor (TVS) diode from Vishay General Semiconductor, part of the 1.5SMC series. It is designed to protect sensitive electronics from voltage transients induced by inductive load switching and lightning. The device features a reverse standoff voltage of 33.3V, a minimum breakdown voltage of 37.1V, and a maximum clamping voltage of 53.9V at a peak pulse current of 27.8A (10/1000μs waveform). With a peak pulse power rating of 1500W and a power dissipation of 6.5W, it offers robust protection for general purpose applications.

 

The diode is housed in a surface mount SMC (DO-214AB) package, suitable for automated placement. It features a glass passivated chip junction, very fast response time, and low incremental surge resistance. The operating temperature range is -65°C to 150°C. The E3 suffix indicates RoHS-compliant commercial grade. The part is not AEC-Q101 qualified.
