The SM15T12AY is a 1500W unidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.
This device features a reverse standoff voltage of 10.2 V and a clamping voltage of 21.7 V. It can handle a peak pulse current of 461 A under an 8/20 µs waveform. The TVS diode utilizes Zener technology for precise voltage clamping and is rated for automotive applications.
The SM15T12AY is housed in a surface-mount DO-214AB (SMC) package, suitable for automated assembly processes. It operates over a junction temperature range of -40°C to 150°C. The part is RoHS3 compliant and has an MSL of 1 (Unlimited).
