DTC114EUAQ

Yangzhou Yangjie Elec Tech · Digital Transistors · SOT-323(SC-70)

DTC114EUAQ from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 via built-in base resistor R1 (7 to 13 kΩ, typ 10 kΩ); input voltage range -10 V to +40 V, VI(off) 0.5 V min at VCC=5V, VI(on) 3 V at IO=10mA.
2 GND power_in Ground, connected to the emitter of the NPN transistor and to R2 (R2/R1 ratio 0.8 to 1.2).
3 OUT output Output, the collector of the NPN transistor; rated VCEO 50 V, IC up to 100 mA, with Vo(on) of 0.3 V max at IO=10mA and II=0.5mA.
