LRC · ESD And Surge Protection (TVS/ESD) · SOT-23
LGSOT12CLT1G from LRC, 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 | One of the two unidirectional Transil terminals; it clamps positive transients just above the logic supply level and negative transients to a diode drop below ground, and pins 1 and 2 can be connected together for bidirectional use. |
| 2 | 2 | passive | The second unidirectional Transil terminal, with the same clamping behaviour as pin 1 for ESD protection of data and transmission lines (IEC61000-4-2 15 kV air, 8 kV contact). |
| 3 | 3 | passive | Common terminal of the dual suppressor array shown on the SOT-23 pin drawing; the datasheet does not explicitly name its function, though the application note describes the array as connected between the signal line and ground. |
