PJSRV05-4 from Leiditech, in a SOT-26. 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 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to the REF1/REF2 references; the part is rated for a 5V operating voltage (VRWM 5V). |
| 2 | REF1 | power_in | Negative reference for the steering diodes, to be connected directly to a ground plane with the path kept as short as possible to minimize parasitic inductance. |
| 3 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to the REF1/REF2 references; the part is rated for a 5V operating voltage (VRWM 5V). |
| 4 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to the REF1/REF2 references; the part is rated for a 5V operating voltage (VRWM 5V). |
| 5 | REF2 | power_in | Positive reference for the steering diodes, connected to VCC in the application circuits; the part is rated for a 5V operating voltage (VRWM 5V). |
| 6 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to the REF1/REF2 references; the part is rated for a 5V operating voltage (VRWM 5V). |
