BSP75NTA from Diodes Incorporated, in a SOT-223-4. 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 | Logic-level input (gate) of the self-protected low-side switch, ESD protected, continuous VIN -0.2 to 10 V (peak -0.2 to 20 V), with protection features specified for VIN of at least 4.5 V. |
| 2 | D | passive | Drain (load side) of the low-side switch, 60 V continuous VDS with active clamp of 60 to 75 V at 10 mA, and it must be electrically isolated from the source tab, with significant copper recommended for thermal performance. |
| 3 | S | power_in | Source pin, which is the ground return of the low-side switch and is connected internally to the tab. |
| 4 | S | power_in | Tab connected to the source pin and it must be electrically isolated from the drain pin. |
