1N4750APF-M

ST(Semtech) · Zener Diodes · DO-41

1N4750APF-M from ST(Semtech), in a DO-41. 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 marked with the cathode band; the 1N4750APF (27 V nominal, 25.65 to 28.35 V at IZT = 9.5 mA) regulates when this pin is positive relative to the anode.
2 A passive Anode, the end opposite the cathode band; forward voltage is max 1.2 V at IF = 200 mA, and power dissipation is limited to 1 W.
