The SM30T19AY is a unidirectional Zener TVS diode from STMicroelectronics, designed for transient voltage suppression in automotive electronics. It offers a maximum clamping voltage of 26V and can handle peak pulse currents up to 115.4A, with a peak pulse power rating of 3kW (3000W). The device is unidirectional, providing protection for a single channel.
This TVS diode is housed in a surface-mount DO-214AB (SMC) package, suitable for automated assembly. It operates over a wide temperature range from -55°C to 175°C, making it robust for harsh automotive environments. The part is specified for automotive applications, ensuring reliability in vehicle electrical systems.
Key electrical characteristics include a Zener technology clamping mechanism. The device does not include power line protection, focusing instead on signal or low-voltage bus protection. The surface-mount SMC package offers a compact footprint for space-constrained designs.
