MUR2040 from LangJie, in a TO-220AB. 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 lead of the MUR2040 20A super fast barrier rectifier, rated for a maximum repetitive peak reverse voltage (VRRM) of 400 V for this part number. |
| 2 | Cathode | passive | Cathode of the rectifier, rated for a maximum average forward rectified current of 10 A at TA=100℃ with 0.375 in (9.5 mm) lead length and a peak forward surge current of 250 A (8.3 ms single half sine wave, JEDEC method). |
| 3 | Anode | passive | Second anode lead of the rectifier, listed as anode in the datasheet pin callout; the datasheet gives no separate electrical limit for this pin. |
