BSP75N

Infineon Technologies · Power Distribution Switches · SOT-223-4

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).

CAD (KiCad official)

  • Symbol: BSP75N
  • Footprint: Package_TO_SOT_SMD:SOT-223
  • 3D model: SOT-223-4 (KiCad packages3D, STEP)
  • 3D model files: bsp75n-etched.step / bsp75n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsp75n.step / bsp75n.glb are the bare package body.
