The single bidirectional channel protects both polarities on one line, which simplifies layout for AC-coupled or bipolar signal lines. ## Peak pulse power and clamping — what the 600W rating means for the board For a 24V supply rail in an industrial controller or automotive body module, this part handles the typical load-dump or inductive kick transient. The 64.3V clamping voltage at 62A peak pulse current gives the downstream circuitry a hard voltage ceiling — the designer sizes the rail capacitance and TVS placement to keep the trace inductance from adding overshoot above that clamp. No power line protection (unidirectional steering is not built in), so for reverse-polarity protection you rely on the bidirectional structure itself. The SMB footprint is shared across the SM6T family, so a layout can accommodate different voltage variants without a board spin. No official replacement has been issued because none is needed; the part is still the factory-recommended choice for new designs requiring a 30.8V bidirectional TVS in the SM6T family.","metaTitle":"STMicroelectronics SM6T36CA TVS Diode, 30.8V Standoff, 600W","metaDescription":"STMicroelectronics SM6T36CA bidirectional TVS diode, 30.8V standoff, 600W peak pulse power, DO-214AA SMB package.
