# MUR3020CTR

**Wild Goose** · Fast Recovery / High Efficiency Diodes · TO-220

MUR3020CTR from Wild Goose, in a TO-220. 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 the first diode leg; the rated per-leg maximum repetitive peak reverse voltage is 200 V to 600 V depending on the variant. |
| 2 | Anode | passive | Common anode of the diode legs; the maximum average forward rectified current is 15 A per leg and 30 A per device. |
| 3 | Cathode | passive | Cathode of the second diode leg; the rated per-leg maximum repetitive peak reverse voltage is 200 V to 600 V depending on the variant. |
