DDTC113ZCA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTC113ZCA-7-F from Diodes Incorporated, in a SOT-23. 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 IN input Input pin, which is the base of the NPN transistor with its built-in input resistor R1; the datasheet gives an input voltage range of -5 to +10 V (pin 1 to pin 2) for DDTC113ZCA.
2 GND (0) power_in Ground pin, which is the emitter of the transistor and the reference for the input and supply voltage ratings.
3 OUT output Output pin, which is the collector of the transistor; the datasheet gives a supply voltage limit VCC of 50 V (pin 3 to pin 2) and an output current limit IO of 100 mA for DDTC113ZCA.
