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). |
