SM15T27AY Description

Short technical summary and product information.

The SM15T27AY from STMicroelectronics is a unidirectional Zener TVS diode designed for transient voltage suppression in automotive applications. Key specifications include a reverse standoff voltage of 23.1V, a clamping voltage of 48.3V, and peak pulse current capability of 207A under 8/20µs waveform. With a peak pulse power rating of 1500W, this device provides robust protection against voltage surges.

 

The diode is housed in a surface-mount DO-214AB (SMC) package and supports an operating temperature range of -40°C to 150°C. It is RoHS3 compliant and REACH unaffected, meeting environmental standards for modern electronics. The unidirectional polarity makes it suitable for DC line protection in 24V automotive systems.

 

Intended for use in automotive electronic modules, the SM15T27AY offers a compact footprint and high reliability. The SMC package is widely used for medium-power transient suppression and is compatible with standard automated assembly processes.
