LR2105LT1G 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 | I/O1 | passive | Protected line 1 (e.g. CAN bus line); steering diode to pin 3, reverse stand-off 24 V max, breakdown 26.2 V min at 5 mA, 30 pF max capacitance. |
| 2 | I/O2 | passive | Protected line 2 (e.g. CAN bus line); steering diode to pin 3, reverse stand-off 24 V max, breakdown 26.2 V min at 5 mA, 30 pF max capacitance. |
| 3 | COMMON | passive | Common pin of the dual diode array, shared by pins 1 and 2 (typically connected to ground), with ±30 kV IEC 61000-4-2 contact and air discharge rating. |
