YFW · Fast Recovery / High Efficiency Diodes · TO-220AB
MUR3020DT from YFW, 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 | PIN1 (anode) | passive | Anode of one diode leg in the common-cathode pair; per-leg typical forward voltage is 1.00 V at 15 A and maximum average reverse current is 5 µA at TJ=25°C (rated DC blocking voltage). |
| 2 | PIN2 & (case) (common cathode) | passive | Common cathode shared by both diode legs and electrically connected to the mounting tab (case); maximum repetitive reverse voltage 200 V, average forward current 30 A, mounting torque 5 in-lbs maximum. |
| 3 | PIN3 (anode) | passive | Anode of the second diode leg in the common-cathode pair; per-leg typical forward voltage is 1.00 V at 15 A and reverse recovery time is 35 ns typical. |
