**LRC** · Switching Diodes · SOT-23

LMBD3004CLT1G 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 | ANODE | passive | Anode terminal of the dual switching diode, which is rated for a 350 V reverse breakdown minimum and 225 mA forward continuous current (Note 1). |
| 2 | ANODE | passive | Anode terminal of the second diode in the dual switching diode, which shares the same 350 V and 225 mA device ratings. |
| 3 | CATHODE | passive | Common cathode terminal of the dual switching diode, sharing the same 350 V and 225 mA device ratings. |
