Leiditech · ESD And Surge Protection (TVS/ESD) · SOT-23-6L
SRV0504 from Leiditech, in a SOT-23-6L. 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 REF1 (pin 2) or REF2 (pin 5); the datasheet gives 0.3 pF typical I/O-to-I/O capacitance and 5 V operating voltage. |
| 2 | REF1 | power_in | Negative reference for the steering diodes, to be connected directly to a ground plane with the shortest possible path to minimize parasitic inductance. |
| 3 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to REF1 (pin 2) or REF2 (pin 5); the datasheet gives 0.3 pF typical I/O-to-I/O capacitance and 5 V operating voltage. |
| 4 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to REF1 (pin 2) or REF2 (pin 5); the datasheet gives 0.3 pF typical I/O-to-I/O capacitance and 5 V operating voltage. |
| 5 | REF2 | power_in | Positive reference for the steering diodes, which clamps protected lines to a fixed positive reference (plus diode VF when exceeded). |
| 6 | I/O | bidirectional | Data line protected by steering diodes that clamp transients to REF1 (pin 2) or REF2 (pin 5); the datasheet gives 0.3 pF typical I/O-to-I/O capacitance and 5 V operating voltage. |
