HDTC144EMT2L

HXY MOSFET · Digital Transistors · SOT-723

HDTC144EMT2L from HXY MOSFET, in a SOT-723. 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 through built-in bias resistor R1 (47 kΩ typ); input voltage range is -10 V to +40 V, with VI(off) min 0.5 V and VI(on) max 3 V.
2 GND power_in Ground connection, emitter side of the NPN digital transistor and return for resistor R2.
3 OUT output Output (collector) of the digital transistor, rated 30 mA continuous output current and 50 V supply voltage maximum.
