DDA124EU-7-F

Diodes Incorporated · Digital Transistors · SOT-363

DDA124EU-7-F from Diodes Incorporated, in a SOT-363. 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 E1 passive Emitter of transistor 1, the supply-voltage reference for pins 6 and 2 (VCC pin 1 to 6 max -50 V), with R2 (22kΩ nominal) connected between emitter and base.
2 B1 input Input of transistor 1 through R1 (22kΩ nominal), with input voltage from pin 1 to pin 2 rated +10 to -40 V.
3 C2 passive Collector (output) of transistor 2, referenced to pin 4 with supply voltage max -50 V and output current rated -30 mA.
4 E2 passive Emitter of transistor 2, the supply-voltage reference for pins 3 and 5 (VCC pin 4 to 3 max -50 V), with R2 (22kΩ nominal) connected between emitter and base.
5 B2 input Input of transistor 2 through R1 (22kΩ nominal), with input voltage from pin 4 to pin 5 rated +10 to -40 V.
6 C1 passive Collector (output) of transistor 1, referenced to pin 1 with supply voltage max -50 V and output current rated -30 mA.
