SAC45

Brightking Elec (TAIWAN) · TVS · DO-15

SAC45 from Brightking Elec (TAIWAN), in a DO-15. 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 color band on the axial DO-15 body (unidirectional device); reverse stand-off voltage VRWM 45.0V, minimum breakdown 50.00V at 1mA for SAC45.
2 A passive Anode, axial lead opposite the cathode band; SAC45 maximum clamping voltage is 77.0V at IPP 6.8A with 500W peak pulse power at 10/1000μs.
