SM15T24AY Description

Short technical summary and product information.

The SM15T24AY is a unidirectional Zener TVS diode designed for automotive applications. It provides transient voltage protection with a reverse standoff voltage of 20.5V and a clamping voltage of 42.8V at a peak pulse current of 234A (8/20µs).

 

With a peak pulse power rating of 1500W, this device is suitable for protecting sensitive circuits from voltage spikes. It does not include power line protection, indicating it is intended for signal or low-power lines.

 

The diode is surface mount packaged in a DO-214AB (SMC) case, with an operating temperature range of -40°C to 150°C. It is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
