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. |
