DTC115EM3T5G from onsemi, in a SOT-723. 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 | BASE | input | Base is the transistor input, which connects through the internal 100 k series input resistor R1 (70 to 130 k), and the datasheet limits the input forward voltage VIN(fwd) to 40 Vdc and the input reverse voltage VIN(rev) to 10 Vdc. |
| 2 | EMITTER | power_in | Emitter is the common reference terminal, labeled GROUND in the datasheet, and it is tied to the internal base-emitter bias resistor R2 (100 k). |
| 3 | COLLECTOR | output | Collector is the transistor output, labeled OUTPUT in the datasheet, with a collector-emitter voltage VCEO of 50 Vdc and a continuous collector current IC of 100 mAdc maximum. |
