The 21.7 V maximum clamping at the rated peak pulse current of 184 A (8/20 µs waveform) defines the worst-case voltage the downstream circuitry must survive. With a single bidirectional channel, this part handles both positive and negative surges on one line, saving board space versus two unidirectional diodes. ## Package and mounting — DO-214AA (SMB) surface-mount The SMB footprint is widely used for TVS diodes in this power class, and the package's small body keeps board area low.","metaTitle":"STMicroelectronics SM6T12CA TVS Diode, 600W Bidirectional","metaDescription":"STMicroelectronics SM6T12CA bidirectional TVS diode, 600W peak pulse power, 10.2V reverse standoff, DO-214AA SMB package.
