LGE · Schottky Barrier Diodes (SBD) · TO-220AC
MBR840 from LGE, in a TO-220AC. 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 | K | passive | Cathode of the Schottky barrier rectifier (MBR840: VRRM 40 V, IF(AV) 8.0 A at TC=125°C, IFSM 150 A); on standard TO-220AC parts it is connected to the metal tab. |
| 2 | A | passive | Anode of the Schottky barrier rectifier (MBR840: VF max 0.7 V at IF=8.0 A, TC=25°C). |
