PSOT05LC-LF-T7
ProTek Devices · ESD And Surge Protection (TVS/ESD) · SOT-23
PSOT05LC-LF-T7 from ProTek Devices, in a SOT-23. 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 | I/O line connection; the datasheet applies positive potential from pin 1 to pin 2 and rates PSOT05LC at 5 V rated stand-off voltage, 500 W peak pulse power (8/20µs) per line. |
| 2 | GND | power_in | Ground reference (datasheet note: pin 2 is ground); do not test or surge from pin 2 to pin 1 because PIV is typically greater than 100 V for the rectifier diode. |
| 3 | NC | unconnected | Not connected in the datasheet's application circuits; the datasheet labels pin 3 as the cathode only for unidirectional devices. |
