The SM15T47AY is a unidirectional automotive TVS diode from STMicroelectronics designed to protect sensitive electronics from voltage transients. It features a reverse standoff voltage of 40.2V and a clamping voltage of 84V, capable of handling peak pulse currents up to 119A (8/20µs waveform) with a peak pulse power rating of 1500W.
This device is housed in a DO-214AB (SMC) surface-mount package, making it suitable for automated assembly processes. It is rated for an operating junction temperature range of -40°C to 150°C, ensuring reliable performance in harsh automotive environments.
Designed specifically for automotive applications, the SM15T47AY provides robust transient voltage suppression for electronic control units, sensors, and other vehicle electronics. Its unidirectional configuration makes it ideal for protecting DC power lines and signal lines from positive-going transients.
