3SMBJ5934B-TP

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

3SMBJ5934B-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, the end identified by the cathode mark on the SMB (DO-214AA) body; for the 3SMBJ5934B it sits at a nominal 24V Zener voltage (VZ) at IZT = 15.6 mA when reverse biased.
2 A passive Anode, the end opposite the cathode mark; forward voltage is at most 1.5V at IF = 200 mA.
