# PSOT24C-LF-T7

**ProTek Devices** · ESD And Surge Protection (TVS/ESD) · SOT-23

PSOT24C-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 | 1 | passive | Pin 1 is one of the three SOT-23 leads shown in the bidirectional pin configuration; the datasheet does not state its specific function for the PSOT24C bidirectional device. |
| 2 | 2 | passive | Pin 2 is one of the three SOT-23 leads shown in the bidirectional pin configuration; the datasheet does not state its specific function for the PSOT24C bidirectional device. |
| 3 | 3 | passive | Pin 3 is the cathode for the unidirectional devices only, per the package notes; the datasheet does not state its function for the bidirectional PSOT24C. |
