SM15T36CAY

SM15T36CAY Description

The SM15T36CAY from STMicroelectronics is a high-performance Transient Voltage Suppression (TVS) diode designed for robust automotive-grade surge protection. Part of the SM15TY, TRANSIL™ series, this bidirectional Zener diode offers a 30.8V reverse standoff voltage and a 34.2V minimum breakdown voltage, ensuring reliable clamping at 64.3V (max) during surge events. With a peak pulse power rating of 1500W (1.5kW) and 156A surge current handling (8/20µs), it excels in dissipating high-energy transients. Packaged in SMC (Surface-Mount Case) and compliant with ROHS3 and REACH, it suits demanding environments.
