The SM30T30AY is a unidirectional Zener TVS diode manufactured by STMicroelectronics. It is designed to protect sensitive electronics from voltage transients, offering a peak pulse power dissipation of 3000W (3kW) under a 10/1000 µs waveform. The device features a clamping voltage of 42.1V and can handle a peak pulse current of 71.3A.
This TVS diode is specifically intended for automotive applications, as indicated by its application designation. It does not include power line protection. The device is surface-mount and packaged in a DO-214AB (SMC) case, with an operating temperature range of -55°C to 175°C. The SMC supplier device package ensures compatibility with standard reflow soldering processes.
With its high surge capability and compact footprint, the SM30T30AY is suitable for protecting automotive electronics such as ECUs, sensors, and infotainment systems from transient overvoltages. The Zener clamping technology provides fast response times and reliable clamping performance.
