SM15T12CAY Description

Short technical summary and product information.

The SM15T12CAY is a bidirectional Zener TVS (Transient Voltage Suppression) diode designed to protect sensitive electronics from voltage transients and surges.

 

This component is rated for a peak pulse power dissipation of 1500W (1.5kW) under 8/20µs waveform conditions, with a corresponding peak pulse current of 461A. It offers a reverse standoff voltage (typical) of 10.2V and a maximum clamping voltage of 21.7V. The device operates over a junction temperature range of -40°C to 150°C.

 

Targeted for automotive applications, the SM15T12CAY is housed in a DO-214AB (SMC) surface mount package, enabling compact PCB assembly. It is not intended for power line protection and does not require external driver circuitry.

 

The Zener diode technology provides fast response and reliable bidirectional clamping for symmetrical transient events.
