SM15T68AY Description

Short technical summary and product information.

The SM15T68AY is a 1500W unidirectional TVS diode from STMicroelectronics designed for automotive applications. It features a reverse standoff voltage of 58.1V and a maximum clamping voltage of 121V, providing robust protection against voltage transients.

 

This device can handle a peak pulse current of 83A under an 8/20µs waveform, making it suitable for suppressing high-energy surges. The Zener technology ensures fast response times and reliable clamping performance.

 

The SM15T68AY is housed in a surface-mount DO-214AB (SMC) package and operates over a junction temperature range of -40°C to 150°C. It is not intended for power line protection, focusing instead on signal and low-voltage circuit protection.
