# 1N5363B

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

1N5363B 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 at the banded end of the DO-201AD body; for the 1N5363B (30 V nominal Zener) it goes positive for Zener regulation, at VZ 30 V at IZT 40 mA, and the DC power dissipation limit is 5.0 W at TL = 75 °C. |
| 2 | A | passive | Anode, the lead at the unbanded end of the DO-201AD body; the forward voltage is 1.2 V maximum at IF = 1 A. |
