PDTC143ZE from Shanghai Prisemi Elec, in a SOT-523. 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 | IN | input | Base input of the built-in bias-resistor inverter (R1 = 4.7 kΩ); VI(on) min 1.3 V at VO = 0.3 V, VI(off) max 0.5 V at VCC = 5 V, and input voltage rated -5 to +30 V. |
| 2 | GND | power_in | Ground reference pin for the device, common to the built-in input and output resistor network. |
| 3 | OUT | output | Output of the transistor stage; absolute maximum output current 100 mA and supply voltage VCC 50 V. |
