The SM4T10AY is a 400W unidirectional Zener TVS diode from STMicroelectronics designed for automotive applications. It features an 8.5V reverse standoff voltage (Vrwm) and a 19.5V clamping voltage, providing robust transient voltage suppression for sensitive circuits.
This device can handle a peak pulse current of 124A under an 8/20µs waveform, making it suitable for protecting against high-energy transients. It is not intended for power line protection, focusing instead on signal and low-power circuit protection.
The SM4T10AY is housed in a surface-mount DO-214AC (SMA) package, offering a compact footprint for space-constrained designs. It operates over a wide temperature range of -55°C to 150°C, ensuring reliability in harsh environments.
