SMAJ48CA

hongjiacheng · ESD And Surge Protection (TVS/ESD) · DO-214AC(SMA)

SMAJ48CA from hongjiacheng, in a DO-214AC(SMA). 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 Bidirectional TVS terminal (SMAJ48CA, no cathode band): stand-off voltage VRWM 48 V, breakdown 53.3 V to 58.9 V at 1 mA, maximum clamping 77.4 V at 5.2 A IPP, interchangeable with the other terminal.
2 A2 passive Bidirectional TVS terminal (SMAJ48CA, no cathode band): stand-off voltage VRWM 48 V, breakdown 53.3 V to 58.9 V at 1 mA, maximum clamping 77.4 V at 5.2 A IPP, interchangeable with the other terminal.
