STMicroelectronics SMA6T22AY Transil™ TVS Diode

The SMA6T22AY is a high-quality Transil™ transient voltage suppression (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is housed in a compact SMA (DO-214AC) package, offering a blend of size efficiency and robust protection for space-constrained applications.

This TVS diode features a stand-off voltage of 22V, which makes it suitable for a variety of applications, including protecting voltage-sensitive components that may experience high surge conditions. The SMA6T22AY is capable of handling a peak pulse power dissipation of 600W (10/1000µs), ensuring reliable protection against high energy transients.

The bidirectional design of the SMA6T22AY allows it to protect circuits from surges occurring in both directions, making it an ideal choice for AC applications or bipolar signals. With a fast response time, this diode reacts quickly to transient overvoltage events, thus safeguarding connected components and extending their operational lifespan.
