SUNMATE Elec · Zener Diodes · DO-201AD
1N5350B from SUNMATE Elec, in a DO-201AD. 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-201AD axial package; the zener is reverse-biased with this lead positive. |
| 2 | A | passive | Anode, the unbanded axial lead of the DO-201AD package. |
