KTH2502QB-ST3 from CONNTEK, 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 | VCC | power_in | Power supply input; the device operates from 2.7 V to 32 V with no external regulator and withstands reverse supply voltage down to -22 V. |
| 2 | OUTPUT | output | Open-drain NMOS output rated for a sink current of up to 30 mA, with output pin voltage limited to 0 V to 32 V and requiring an external pull-up resistor. |
| 3 | GND | power_in | Ground reference pin for the device. |
