The SM15T39AY is a unidirectional TVS diode from STMicroelectronics designed for transient voltage suppression. It features a reverse standoff voltage of 33.3V and a clamping voltage of 69.7V, with a peak pulse power rating of 1500W (8/20µs waveform).
The device provides protection for sensitive electronics against voltage transients. It handles peak pulse currents up to 143A (8/20µs) and operates over a junction temperature range of -40°C to 150°C.
The SM15T39AY is housed in a DO-214AB (SMC) surface-mount package suitable for automated assembly. It is rated for automotive applications.
Environmental compliance data indicates RoHS3 compliance, MSL level 1 (unlimited), and REACH unaffected, though these are unverified from manufacturer sources.
