DDTA124TE-7-F

Diodes Incorporated · Digital Transistors · SOT-523

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.
