# 1N5368B

**SUNMATE Elec** · Zener Diodes · DO-201AD

1N5368B 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 lead on the banded end of the DO-201AD body; it goes positive for zener (reverse) operation, with a nominal VZ of 47 V at IZT = 25 mA for the 1N5368B. |
| 2 | A | passive | Anode, the lead at the end opposite the cathode band; forward voltage is at most 1.2 V at IF = 1 A. |
