The SM4T23AY is a unidirectional Zener TVS (Transient Voltage Suppression) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients, particularly in automotive environments. The device offers a peak pulse power dissipation of 400W (10/1000µs waveform) and can handle a peak pulse current of 54A under the same conditions.
With a typical reverse standoff voltage of 20V and a minimum breakdown voltage of 21.7V, the SM4T23AY provides reliable clamping at a maximum voltage of 42.8V. This diode is not intended for power line protection, making it suitable for low-voltage signal and data line protection.
The SM4T23AY is housed in a surface-mount DO-214AC (SMA) package, allowing for compact PCB layout. It operates over a wide temperature range of -55°C to 150°C (junction temperature). The device is qualified for automotive applications, ensuring robustness under harsh conditions.
Compliance information indicates RoHS3 compliance, REACH unaffected, and MSL 1 (unlimited).
