Nexperia · Digital Transistors · SOT-23
PDTB123YT from Nexperia, in a SOT-23. 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 resistor-equipped PNP transistor, with bias resistor R1 = 2.2 kΩ (±10 %); the input voltage is limited to +5 V positive and -20 V negative. |
| 2 | GND | power_in | Ground (emitter) connection of the transistor; the datasheet specifies it as the emitter terminal and gives no separate voltage limit for this pin. |
| 3 | O | output | Output (collector) of the transistor, rated for a maximum output current of -500 mA with VCEO of -50 V. |
