1.5SMC33A-E3/57T Description

Short technical summary and product information.

The 1.5SMC33A-E3/57T is a unidirectional Zener TVS diode from Vishay Dale's 1.5SMC series. It features a reverse standoff voltage of 28.2V and a maximum clamping voltage of 45.7V at a peak pulse current of 32.8A (10/1000µs waveform). The device is rated for 1500W peak pulse power and offers very fast response time for transient voltage suppression.

 

This TVS diode is designed for general purpose protection of sensitive electronics against voltage transients from inductive load switching and lightning. It is housed in a DO-214AB (SMC) surface mount package with matte tin plated leads and is RoHS-compliant. The operating temperature range spans -65°C to 150°C, and the device meets MSL level 1 per J-STD-020.
