The SM15T18AY is a unidirectional automotive TVS diode from STMicroelectronics designed to protect sensitive electronics from voltage transients. It features a reverse standoff voltage of 15.3V and a maximum clamping voltage of 32.5V, ensuring robust protection for automotive applications.
With a peak pulse power rating of 1500W (1.5kW) and a peak pulse current of 308A (8/20µs), this device can handle high-energy surges. It is not intended for power line protection, making it suitable for signal and data line protection in automotive environments.
The SM15T18AY is housed in a DO-214AB (SMC) surface-mount package and operates over a junction temperature range of -40°C to 150°C. Its surface-mount design facilitates automated assembly and space-efficient layouts on PCBs.
