1N5260BPF from ST(Semtech), in a DO-35. 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 by the cathode band on the DO-35 glass case; this is the Zener voltage reference terminal (VZnom 43 V for 1N5260B, 40.85 to 45.15 V at IZT 3 mA). |
| 2 | A | passive | Anode, the lead opposite the cathode band on the DO-35 glass case; forward voltage VF max 1.1 V at IF = 200 mA. |
