MUR20H60 from Changjing, in a TO-220-2L. 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 hyperfast rectifier; withstands VRRM 600V peak repetitive reverse voltage and carries IF(AV) 20A average forward current (TC=94℃). |
| 2 | ANODE | passive | Anode of the hyperfast rectifier; forward voltage is 2.15V typ (2.5V max) at IF=20A, Tj=25℃, and non-repetitive surge current IFSM is 240A (8.3ms). |
