SMAJ28CA

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

SMAJ28CA 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 1 of 2, interchangeable with the other terminal (no cathode band on bidirectional devices), 28V VRWM, 31.1V to 34.4V breakdown at 1mA, 45.4V max clamping at 8.8A IPP.
2 A2 passive Bidirectional TVS terminal 2 of 2, interchangeable with the other terminal (no cathode band on bidirectional devices), 28V VRWM, 31.1V to 34.4V breakdown at 1mA, 45.4V max clamping at 8.8A IPP.
