LESD8D12CBT5G from LRC, in a SOD-882. 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 | ESD protection diode terminal 1 for a 12 V working reverse voltage (VRWM 12 V), rated to IEC 61000-4-2 ±30 kV air and ±30 kV contact discharge; the datasheet does not state which terminal is the anode or cathode. |
| 2 | 2 | passive | ESD protection diode terminal 2 for a 12 V working reverse voltage (VRWM 12 V), rated to IEC 61000-4-2 ±30 kV air and ±30 kV contact discharge; the datasheet does not state which terminal is the anode or cathode. |
