The SM4T68AY is a unidirectional Zener TVS diode from STMicroelectronics designed for overvoltage protection in automotive applications. It features a reverse stand-off voltage of 58 V and a clamping voltage of 121 V, providing robust protection against transient voltage spikes.
With a peak pulse power rating of 400 W and a peak pulse current of 19 A (8/20 µs), this device is suitable for suppressing high-energy transients. The operating junction temperature range is -55°C to 150°C, ensuring reliable performance in harsh environments.
The SM4T68AY is housed in a DO-214AC (SMA) surface-mount package, making it ideal for automated assembly and space-constrained designs. It is RoHS3 compliant and REACH unaffected, with an MSL of Level 1 for unlimited floor life.
