SM15T39CAY Description

Short technical summary and product information.

The STMicroelectronics SM15T39CAY is a TVS (Transient Voltage Suppressor) Diode belonging to the TRANSIL series, specifically designed for automotive applications. This unidirectional/bidirectional device operates at a nominal voltage of 33.3V, with a reverse standoff voltage of 33.3V and a breakdown voltage ranging from 37.1V to 41V.

 

It provides robust protection with a clamping voltage of 69.7V at a peak pulse current of 143A (8/20µs), and can handle a peak pulse power of 1.5kW. The diode features a maximum reverse leakage current of 1uA and a maximum surge current of 28A. It is designed for surface mount applications in an SMC package.

 

Operating within a temperature range of -40°C to 150°C, the SM15T39CAY is suitable for demanding environments. Its RoHS 3 compliant status and Lead Free construction further enhance its suitability for modern electronic designs. The device is packaged in tape and reel for automated assembly processes.
