NHDTA143ZTR 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 | I | input | Input (base) of the built-in PNP transistor, applied through the 4.7 kΩ bias resistor R1; for the NHDTA143ZT the input voltage limit is -30 V to +7 V. |
| 2 | GND | power_in | GND (emitter) pin, the common reference for the input and the emitter of the built-in transistor. |
| 3 | O | output | Output (collector) pin; the output current is limited to -100 mA and the collector-emitter voltage VCEO to -80 V (open base). |
