# 1N4760A

**XCH(旭昌辉)** · Zener Diodes · DO-41

1N4760A from XCH(旭昌辉), in a DO-41. 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 colour-band end of the DO-41 body; the zener is reverse biased with this lead positive (1N4760A: 68 V nominal, 3.7 mA IZT, 1.0 W DC dissipation at TL = 75 °C). |
| 2 | A | passive | Anode, the lead opposite the colour band; maximum forward voltage is 1.2 V at 200 mA and junction/storage range is -55 to +150 °C. |
