SM15T6V8A

STMicroelectronics · TVS · SMC

SM15T6V8A from STMicroelectronics, in a SMC. 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 of the unidirectional TVS diode, marked by the cathode band on the package; connect to the protected line, with VRM 5.8 V and VBR 6.45 V min to 7.14 V max at 10 mA for SM15T6V8A.
2 A passive Anode of the unidirectional TVS diode, normally connected to ground; clamps to VCL max 10.5 V at 143 A (10/1000 µs) for SM15T6V8A.
