XCH(旭昌辉) · IC · DO-41
1N4754A 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 end marked by the color band; the Zener breakdown (VZ) is reached when this pin is positive relative to the anode, and the nominal 1N4754A VZ is 39 V at IZT 6.5 mA. |
| 2 | A | passive | Anode, the end without the color band; forward voltage is at most 1.2 V at 200 mA, and the device is rated 1.0 W at TL = 75 °C. |
