GBLC12C-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 terminal of the bidirectional GBLC12C TVS line, rated for a 12 V stand-off voltage (VWM) with 13.3 V minimum breakdown at 1 mA and 19.0 V maximum clamping at IP = 1 A, with 350 W peak pulse power (8/20 µs) per line. The datasheet does not assign polarity to either terminal of the bidirectional part. |
| 2 | 2 | passive | Second terminal of the bidirectional GBLC12C TVS line, with the same 12 V stand-off, 13.3 V minimum breakdown and 19.0 V maximum clamping limits as pin 1. The datasheet notes that the 'Positive potential is applied from pin 1 to 2' rule applies only to unidirectional devices. |
