DDTC123JE-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 to the built-in base bias resistor R1; the input voltage (1 to 2) is limited to -5 V to +12 V for DDTC123JE per the Maximum Ratings. |
| 2 | GND | power_in | Common ground reference for the input and supply; the input voltage and supply voltage ratings are both specified to this pin. |
| 3 | OUT | output | Output at the collector of the internal NPN transistor; supply voltage (3 to 2) is rated 50 V max and output current is 100 mA max for DDTC123JE. |
