The SM4T15AY is a unidirectional TVS (Transient Voltage Suppression) diode from STMicroelectronics, designed to protect sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 13V and a maximum clamping voltage of 27.2V. The device can handle peak pulse currents up to 85A (8/20 µs waveform) and offers a peak pulse power rating of 400W.
This TVS diode utilizes Zener technology and is optimized for automotive applications, operating over a wide temperature range from -55°C to 150°C. It is a single-channel device with no power line protection, making it suitable for signal line protection in automotive electronics.
The SM4T15AY is supplied in a surface-mount DO-214AC (SMA) package, which is compact and suitable for automated assembly. The package is RoHS3 compliant and has an MSL rating of 1 (unlimited).
