DTC114YUAQ

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

DTC114YUAQ 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 terminal to base through built-in R1 (7 to 13 kΩ, typ 10 kΩ); input voltage range -6 V to +40 V, VI(off) 0.3 V min at VCC=5 V, VI(on) 1.4 V max.
2 GND power_in Ground terminal connected to the emitter and to R2 of the built-in bias network.
3 OUT output Output terminal at the collector; VCEO 50 V, collector current up to 100 mA, Vo(on) 0.3 V max at Io=5 mA.
