**HUAKE** · Schottky Diodes · TO-252

MBR20100DR from HUAKE, 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 of the first Schottky diode leg, rated 10 A average per leg with VRRM 100 V. |
| 2 | K | passive | Common cathode of both legs, brought out on the metal tab (the centre lead is a short stub in the drawing); VR 100 V maximum. |
| 3 | A2 | passive | Anode of the second Schottky diode leg, rated 10 A average per leg with VRRM 100 V. |
