SMBJ5340B-TP

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

SMBJ5340B-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 (marked with the cathode band); the 6 V ±5% zener voltage is regulated at IZT = 200 mA with ZZT max 1 ohm, IR max 1 µA at VR = 3 V, and IZM max 790 mA.
2 A passive Anode; forward voltage VF is 1.2 V max at 1.0 A, and steady-state power dissipation is 5 W with lead temperature at 75°C.
