SZ1.5SMC51AT3G Description

Short technical summary and product information.

The SZ1.5SMC51AT3G is a unidirectional transient voltage suppressor (TVS) diode from Littelfuse, designed for automotive applications. It provides 1500W peak pulse power protection with a reverse standoff voltage of 43.6V and a clamping voltage of 70.1V. The device can handle a peak pulse current of 21.4A (8/20μs waveform).

 

This TVS diode is housed in a DO-214AB (SMC) surface mount package, suitable for automated assembly. It operates over a wide temperature range of -65°C to 150°C, making it robust for harsh environments. The unidirectional configuration protects against positive voltage transients.

 

Key specifications include a 43.6V working voltage, 70.1V clamping voltage, and 1500W peak pulse power rating. The device is RoHS3 compliant and REACH unaffected, supporting automotive-grade reliability requirements.
