ST Semtech · Zener Diodes · DO-41
1N4743APF-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 lead at the black cathode-band end of the DO-41 glass case; the 13 V Zener (12.35 to 13.65 V at IZT = 19 mA) is reverse-biased with this lead positive. |
| 2 | A | passive | Anode, the lead at the end opposite the cathode band; forward voltage is max 1.2 V at IF = 200 mA. |
