SM30T35AY Description

Short technical summary and product information.

The SM30T35AY is a unidirectional Zener-type TVS diode designed for automotive applications. It features a reverse standoff voltage of 30V and a maximum clamping voltage of 48.4V at the peak pulse current of 62A (10/1000µs waveform). The device can handle 3000W (3kW) of peak pulse power, making it suitable for protecting sensitive electronics from voltage transients.

 

This TVS diode is housed in a DO-214AB (SMC) surface-mount package, which is compatible with standard SMD assembly processes. It operates over a wide temperature range from -55°C to 175°C, ensuring reliability in harsh automotive environments. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited).

 

As an automotive-grade component, the SM30T35AY is ideal for use in engine control units, infotainment systems, and other vehicle electronics where transient voltage protection is critical. Its unidirectional configuration provides efficient clamping for positive-going surges.
