SMBJ12CA

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

SMBJ12CA 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 Bi-directional TVS terminal 1 (SMBJ12CA, VRWM 12.0V, VBR 13.30-14.70V at 1mA, VC 19.9V at IPP 30.15A); no polarity, no cathode band on bi-directional parts.
2 A2 passive Bi-directional TVS terminal 2 (SMBJ12CA, 600W peak pulse power at 10/1000µs); interchangeable with terminal 1 since the part is symmetric.
