SM6T15A

STMicroelectronics · TVS · SMB(DO-214AA)

SM6T15A from STMicroelectronics, in a SMB(DO-214AA). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, marked by the band on unidirectional (A) types; the SM6T15A clamps at VCL 21.2 V max at 28 A (10/1000 µs) with VBR 14.3-15.8 V and VRM 12.8 V.
2 A passive Anode of the unidirectional SM6T15A Transil; a bidirectional CA type has no polarity, but the SM6T15A is unidirectional.
