BSP75N from Infineon Technologies, in a SOT-223-4. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Logic level input (VIN = -0.2 to +10 V continuous, -0.2 to +20 V peak) with 4 kV ESD protection that enables the output stage and supplies internal logic. |
| 2 | DRAIN | tri_state | Open drain output (VDS = 60 V continuous) with integrated overvoltage clamp (60-75 V), current limit (1.5 A typical), and short circuit protection. |
| 3 | SOURCE | power_in | Ground return and source reference (internally connected to TAB) for load current path and internal protection function measurement. |
| 4 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
