SM15T22A Description

Short technical summary and product information.

The SM15T22A is a unidirectional TVS (transient voltage suppression) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronics from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.

 

Key electrical specifications include a reverse standoff voltage of 18.8 V, a maximum clamping voltage of 39.3 V, and a peak pulse current rating of 254 A under an 8/20 µs waveform. The device can handle a peak pulse power of 1500 W, making it suitable for medium-power surge protection applications.

 

The SM15T22A uses Zener clamping technology and is a single-channel unidirectional device. It is typically housed in an SMC (DO-214AB) package, suitable for surface-mount assembly.
