BSP135IXTSA1

Infineon Technologies · MOSFETs · SOT-223-4

BSP135IXTSA1 from Infineon Technologies, 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 Gate input Gate of the N-channel depletion-mode MOSFET (Pin 1 in the page 1 symbol).
2 Drain passive Drain of the MOSFET, rated for VDS of 600 V, and connected internally to Pin 4 (Drain Pin 2, 4).
3 Source passive Source of the N-channel depletion-mode MOSFET (Pin 3 in the page 1 symbol).
4 Drain passive Drain tab of the SOT-223-4 package, the same drain node as Pin 2 (Drain Pin 2, 4).

CAD (KiCad official)

  • Symbol: BSP135IXTSA1
  • Footprint: Package_TO_SOT_SMD:SOT-223
  • 3D model: SOT-223-4 (KiCad packages3D, STEP)
  • 3D model files: bsp135ixtsa1-etched.step / bsp135ixtsa1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsp135ixtsa1.step / bsp135ixtsa1.glb are the bare package body.
