SMBJ40CA

hongjiacheng · ESD And Surge Protection (TVS/ESD) · DO-214AA(SMB)

SMBJ40CA from hongjiacheng, in a DO-214AA(SMB). 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 Terminal 1 of the bi-directional SMBJ40CA TVS, interchangeable with the other terminal, with 40.0V reverse stand-off voltage, 44.40-49.10V breakdown at 1mA and 64.5V maximum clamping at 9.30A IPP.
2 A2 passive Terminal 2 of the bi-directional SMBJ40CA TVS, interchangeable with the other terminal, with no cathode band because the band marks uni-directional parts only.
