**LRC** · Switching Diodes · SOT-323-3

LM1MA142WAT1G from LRC, in a SOT-323-3. 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 | CATHODE | passive | Cathode of one of the two diodes in the common-anode pair; the LM1MA142WAT1G has an 80 Vdc maximum reverse voltage and a 150 mAdc dual forward current rating. |
| 2 | CATHODE | passive | Cathode of the other diode in the common-anode pair; the LM1MA142WAT1G has an 80 Vdc maximum reverse voltage and a 150 mAdc dual forward current rating. |
| 3 | ANODE | passive | Common anode shared by both diodes; the LM1MA142WAT1G has an 80 Vdc maximum reverse voltage and a 150 mAdc dual forward current rating. |
