HDTC143ZCAT116

HXY MOSFET · Digital Transistors · SOT-23

HDTC143ZCAT116 from HXY MOSFET, in a SOT-23. 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 Base input of the digital transistor through the internal bias resistor R1 (3.3 to 4.7 kΩ in the table); only on/off conditions need to be set, and the isolated thin-film resistors allow negative biasing of the input.
2 GND power_in Ground, connected to the emitter of the digital transistor.
3 OUT output Collector output, rated for VCEO 50 V and IC 100 mA maximum, with VCE(sat) of 0.25 V maximum at IC = 10 mA.
