GBLC03CI-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 | One of the two line terminals of the bidirectional GBLC03CI TVS array, which protects one power or I/O port; the line has a 3.0 V rated stand-off voltage, 4.0 V minimum breakdown at 1 mA, and 7.0 V maximum clamping at IP = 1 A. |
| 2 | 2 | passive | The second line terminal of the bidirectional GBLC03CI TVS array, which protects one power or I/O port; the datasheet gives 5 µA maximum leakage at VWM and 0.6 pF typical capacitance per line. |
