HMUN5211T1G from HXY MOSFET, in a SOT-523. 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 with built-in bias resistor R1 (7 to 13 kΩ, 10 kΩ typ) allowing negative biasing; input voltage range -10 V to +40 V. |
| 2 | GND | power_in | Ground pin of the digital transistor, common reference for input and output. |
| 3 | OUT | output | Output (collector) pin rated for 50 mA output current (100 mA peak) with VO(on) max 0.3 V at IO/II=10mA/0.5mA. |
