SA48CA

Brightking Elec (TAIWAN) · TVS · DO-15

SA48CA 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 A1 passive Axial lead 1 of the bidirectional SA48CA (no polarity, no cathode band); reverse stand-off voltage 48.0V, breakdown 53.30~58.90V at 1mA, max clamping 77.4V at 6.6A peak pulse current.
2 2 passive Axial lead 2 of the bidirectional SA48CA (interchangeable with lead 1); reverse leakage 1μA at VRWM, 500W peak pulse power at 10/1000μs.
