SM30T18CAY Description

Short technical summary and product information.

The SM30T18CAY is a bidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge. This device is specifically rated for automotive applications.

 

Key electrical specifications include a reverse standoff voltage of 15 V, a clamping voltage of 24.4 V, and a peak pulse current capability of 123 A. The device can handle a peak pulse power dissipation of 3000 W (3 kW) for a 10/1000 µs waveform. It is a single bidirectional channel device and does not provide power line protection.

 

The SM30T18CAY is housed in a surface-mount DO-214AB (SMC) package, which is suitable for automated assembly processes. It has an operating temperature range of -55°C to 175°C, making it suitable for harsh environments. The supplier device package is SMC.
