SM15T75AY Description

Short technical summary and product information.

The SM15T75AY is a 1500W unidirectional TVS (Transient Voltage Suppression) diode manufactured by STMicroelectronics. Designed for automotive applications, this device provides robust protection against voltage transients with a peak pulse power rating of 1500W (8/20µs). It features a reverse standoff voltage of 64.1V, a nominal breakdown voltage of 75V, and a maximum clamping voltage of 134V at a peak pulse current of 75A (8/20µs). The diode is not intended for power line protection.

 

The device is housed in a DO-214AB (SMC) surface-mount package, suitable for automated assembly. It supports a wide operating temperature range from -40°C to 150°C. The unidirectional design makes it ideal for single-line protection in automotive electronic systems, such as engine control units, infotainment, and sensor interfaces.

 

The SM15T75AY is RoHS3 compliant (unverified) and has a moisture sensitivity level of 1 (unlimited). It is recommended for applications requiring high surge capability and fast response to transient events.
