MBR10100CT from XUMAO, 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 | A1 | passive | Anode of the first Schottky diode of the dual common-cathode pair, as shown by the polarity symbol on the marking drawing. |
| 2 | K | passive | Common cathode of both Schottky diodes (center pin), shown by the polarity symbol on the marking drawing, with 100 V maximum DC blocking voltage. |
| 3 | A2 | passive | Anode of the second Schottky diode of the dual common-cathode pair, as shown by the polarity symbol on the marking drawing. |
