DTC014YUBTL

ROHM Semicon · Digital Transistors · SOT-323

DTC014YUBTL 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 IN input Input (base) of the NPN digital transistor, connected through built-in R1 = 10kΩ with R2 = 47kΩ to emitter; VI(off) max 0.5V, VI(on) min 1.7V, input voltage rating 40 to -6 V.
2 GND power_in Ground (emitter) of the built-in transistor, common return for the bias resistor R2.
3 OUT passive Output (collector) of the built-in transistor, rated for VCC 50V and IC(MAX) 100mA (output current IO 70mA).
