The SM4T12CAY is a bidirectional TVS diode from STMicroelectronics designed for transient voltage suppression. It features a reverse standoff voltage of 10V and a maximum clamping voltage of 21.7V. With a peak pulse power rating of 400W and a peak pulse current of 106A (8/20µs), it provides robust protection against voltage transients. The device is rated for operating temperatures from -55°C to 150°C. Housed in a surface-mount SMA (DO-214AC) package, it is suitable for space-constrained designs. The SM4T12CAY is specifically intended for automotive applications. It is listed as RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited).
