DTC144EKA

MSKSEMI · Bipolar (BJT) · SOT-23-3L

DTC144EKA from MSKSEMI, in a SOT-23-3L. 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 of the built-in bias-resistor inverter, with input resistance R1 of 32.9 to 61.1 kΩ (47 kΩ typical) and an input voltage rating of -10 V to +40 V.
2 GND power_in Ground (common) reference pin of the device.
3 OUT output Output pin of the transistor stage, rated for an output current of 30 mA and a peak collector current of 100 mA.
