SA45A

Brightking · ESD And Surge Protection (TVS/ESD) · DO-15

SA45A from Brightking, 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, the axial lead on the color-band side of the unidirectional SA45A (VRWM 45.0 V, VBR 50.00~55.30 V at 1 mA, VC 72.7 V at 7.0 A IPP).
2 A passive Anode, the axial lead opposite the cathode band; it is the lead that goes negative relative to the cathode in normal use, with the diode clamping in reverse breakdown (IR 1 µA max at VRWM 45.0 V).
