Nexperia · LED Drivers · TO-236AB
NCR401TR from Nexperia, in a TO-236AB. 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 | GND | power_in | Ground reference; ground current is 340 to 500 µA at VSUP = 10 V and IO = 0 A. |
| 2 | VSUP | power_in | Supply voltage input, maximum 18 V. |
| 3 | IO/VO | output | Constant-current output (10 mA typ, 8.5 to 11.5 mA) driving the LED; maximum output voltage 16 V at VSUP = 18 V. |
