DDTA144VUA-7-F from Diodes Incorporated, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Input pin - connects to base through built-in R1 = 47kΩ series resistor (with R2 = 10kΩ from base to emitter). Drives the PNP transistor's base for switching. VIN rating +15 to -40V; VI(off) ≥ -1.0V; VI(on) typ -5.0V; input current at VI = -5V typ -0.16mA. |
| 2 | GND | passive | Ground / emitter (+) terminal of the PNP pre-biased transistor. For PNP digital transistors this is the positive supply reference (labeled GND(+) in the datasheet). |
| 3 | OUT | output | Output pin - collector of the PNP transistor. Open-collector style output. Supply/output voltage rating VCC = -50V (pin 3 to pin 2); IO max = -30mA; IO(off) ≤ -0.5µA at VCC = -50V, VI = 0V. |
