DCX143TU-7-F

Diodes Incorporated · Digital Transistors · SOT-363

DCX143TU-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 C1 passive Collector/output terminal of the first transistor section; the DCX143TU output current is rated 100 mA (IO) and 100 mA peak (ICM) with a 50 V supply rating.
2 B2 input Base/input terminal of the second transistor section, which feeds the R1 input resistor (4.7 kΩ nominal, ±30% tolerance); input voltage is limited to -5 V max for the NPN section and +5 V max for the PNP section.
3 E2 passive Emitter/common terminal of the second transistor section, rated with the same 50 V supply and ±100 mA output current limits as the DCX143TU.
4 C2 passive Collector/output terminal of the second transistor section; the DCX143TU output current is rated 100 mA (IO) and 100 mA peak (ICM).
5 B1 input Base/input terminal of the first transistor section, which feeds the R1 input resistor (4.7 kΩ nominal, ±30% tolerance); input voltage is limited to -5 V max for the NPN section and +5 V max for the PNP section.
6 E1 passive Emitter/common terminal of the first transistor section, rated with the same 50 V supply and ±100 mA output current limits as the DCX143TU.
