DDTA124TUA-7-F

Diodes Incorporated · Digital Transistors · SOT-323

DDTA124TUA-7-F from Diodes Incorporated, in a SOT-323. 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 terminal, connected to the transistor base through the built-in input resistor R1; the input voltage must stay within the per-variant limits in the Maximum Ratings table (for example +10 V to -40 V for DDTA124XUA).
2 GND power_in Ground/emitter reference terminal (labelled GND(+) in the datasheet) that is common to the input and output circuits and is also the base-emitter resistor R2 reference.
3 OUT output Output terminal, the collector of the PNP transistor; output current is limited per variant, to -100 mA for most parts and -50 mA for DDTA124XUA in the Maximum Ratings table.
