BSP78HUMA1 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 control input (Gate driver input). Drives the internal gate-driving unit through the ESD/input-protection network. Threshold V(IN(th)) typ. 1.7 V, on-state input current I(IN(on)) typ. 10 µA at V(IN) = 5 V; continuous input voltage range -0.2 V to +10 V (input current self-limited within this window). |
| 2 | Drain | power_in | Drain of the internal power N-MOSFET; connects to the load / V(bb) supply side through the load. Shared with pin 4 via the SOT-223 heat-spreader tab. Absolute max V(DS) = 42 V; drain-source clamp voltage V(DS(AZ)) = 42 V min / 55 V max at I(D) = 10 mA. |
| 3 | Source | power_in | Source of the internal N-MOSFET and common ground reference for the logic input. In a low-side switch application this pin is connected to system GND. |
| 4 | Drain | power_in | Drain (TAB). Electrically identical to pin 2; the exposed SOT-223 tab used as the primary thermal path for the drain metallisation. |
