DDTA124EUA-7-F

Diodes Incorporated · Digital Transistors · SOT-323

DDTA124EUA-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 of the built-in bias network (R1 = R2 = 22 kΩ); input voltage is rated +10 to -40 V for DDTA124EUA.
2 GND power_in Ground reference and emitter terminal of the inverter circuit, with supply voltage VCC rated -50 V maximum.
3 OUT output Collector output of the inverter; output current is rated -30 mA for DDTA124EUA.
