DDTA124TE-7-F from Diodes Incorporated, 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 | Input pin connected to the base through the built-in 22kΩ (nominal) R1 bias resistor; the datasheet gives no separate input voltage limit. |
| 2 | GND | power_in | Ground pin connected to the emitter of the PNP transistor, serving as the circuit reference. |
| 3 | OUT | output | Output pin connected to the collector; limits are VCEO -50 V, VCBO -50 V and peak collector current -100 mA (single pulse), with PD 150 mW. |
