SUNMATE Elec · Zener Diodes · DO-201AD
1N5369B 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, the end marked with the cathode band; in Zener operation it is taken positive to the anode, with DC power dissipation limited to 5.0 W. |
| 2 | A | passive | Anode, the lead opposite the cathode band; forward voltage is at most 1.2 V at IF = 1 A. |
