GBLC03C-LF-T7 from ProTek Devices, in a SOD-323. 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 | Bidirectional TVS terminal (GBLC03C, no polarity) protecting one line, with 3.3V rated stand-off voltage, 4.0V minimum breakdown at 1mA and 7.0V maximum clamping at 1A. |
| 2 | 2 | passive | Bidirectional TVS terminal (GBLC03C, no polarity) connected to the protected line or ground return, with 3pF typical capacitance at 0V, 1MHz and 5µA maximum leakage at VWM. |
