DDA124EH-7
Diodes Incorporated · Digital Transistors · SOT-563
DDA124EH-7 from Diodes Incorporated, in a SOT-563. 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 PNP transistor 1, with the R2 base-emitter resistor (22kΩ on DDA124EH) connected to it. |
| 2 | B1 | input | Base (input) of transistor 1 through the series R1 resistor (22kΩ on DDA124EH); input voltage range +10 to -40V. |
| 3 | C2 | passive | Collector (output) of transistor 2; output current rated -30mA for DDA124EH. |
| 4 | E2 | passive | Emitter of PNP transistor 2, with the R2 base-emitter resistor (22kΩ on DDA124EH) connected to it. |
| 5 | B2 | input | Base (input) of transistor 2 through the series R1 resistor (22kΩ on DDA124EH); input voltage range +10 to -40V. |
| 6 | C1 | passive | Collector (output) of transistor 1; output current rated -30mA for DDA124EH. |
