# MUR2080CT

**LGE** · Fast Recovery / High Efficiency Diodes · TO-220AB

MUR2080CT from LGE, 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 | A1 | passive | Anode of the first 10A diode element, with its cathode tied to the common PIN2 (MUR2080CT, 800V VRRM). |
| 2 | CATHODE (COMMON) | passive | Common cathode of both diode elements, connected to the mounting tab, for the MUR2080CT (VRRM 800V, 20A total average forward current at TC=95C). |
| 3 | A2 | passive | Anode of the second 10A diode element, with its cathode tied to the common PIN2 (MUR2080CT, 800V VRRM). |
