SC2498SO from Semiment, in a SOT-23-3. 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 | VDD | power_in | Supply input for the 2.8 to 40 V operating range; the device withstands transients up to 45 V and does not operate between -0.5 V and 2.5 V. |
| 2 | OUT | output | Open-drain NMOS output that requires an external pull-up resistor, may be pulled up to VDD or another voltage (VPULL), and is rated to sink up to 30 mA with output saturation of 500 mV max at 20 mA. |
| 3 | GND | power_in | Ground terminal, the reference for VDD. |
