SMBJ5369B-TP

MCC(Micro Commercial Components) · Zener Diodes · SMB(DO-214AA)

SMBJ5369B-TP from MCC(Micro Commercial Components), in a SMB(DO-214AA). 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 K passive Cathode terminal, identified by the cathode band on the package marking; the SMBJ5369B has a nominal VZ of 51V at 25mA test current.
2 A passive Anode terminal, opposite the cathode band; the device is rated 5W steady-state dissipation with a 1.2V maximum forward voltage at 1.0A.
