DTC124EUAFRAT106

ROHM Semicon · Digital Transistors · SOT-323

DTC124EUAFRAT106 from ROHM Semicon, in a SOT-323. 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 GND (EMITTER) power_in Ground / emitter of the built-in NPN transistor, connected to R2 as shown in the inner circuit.
2 IN (BASE) input Input / base of the transistor through built-in R1 = 22kΩ, with input voltage rated -10 to 40 V and VI(off) max 0.5 V, VI(on) min 3.0 V.
3 OUT (COLLECTOR) output Output / collector of the transistor, with supply voltage VCC max 50 V and collector current IC(MAX) 100 mA.
