The SM6T12AY is a unidirectional Zener TVS diode manufactured by STMicroelectronics, designed for transient voltage suppression in automotive and industrial applications. It offers a reverse standoff voltage of 10.2V and a maximum clamping voltage of 21.7V, capable of handling 600W peak pulse power (8/20µs waveform) with a peak pulse current of 184A.
This device is housed in a surface-mount DO-214AA (SMB) package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C, ensuring reliability in harsh environments. The part is specified for automotive applications, meeting demanding surge and ESD protection requirements.
As a Zener-based TVS diode, the SM6T12AY provides precise voltage clamping for protecting sensitive electronics from overvoltage transients. It is unidirectional, making it ideal for DC lines where a single polarity reference is needed. Key specifications include a 10.2V standoff, 21.7V clamp, 600W peak pulse power, and 184A peak pulse current under 8/20µs conditions.
