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. |
