MBR20100DY from Shandong Jingdao Microelectronics, in a TO-252. 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 input of the Schottky rectifier, shown tied with PIN3 to the diode anode in the page 1 symbol; part rated 100 V VRRM and 20 A average forward current. |
| 2 | K | passive | Cathode of the Schottky rectifier, also the exposed tab (PIN2 is labelled on both the tab and the centre lead); 100 V maximum DC blocking voltage. |
| 3 | A2 | passive | Anode input of the Schottky rectifier, shown tied with PIN1 to the diode anode in the page 1 symbol; part rated 100 V VRRM and 20 A average forward current. |
