**MDD（Microdiode Electronics）** · Schottky Barrier Diodes (SBD) · TO-277

ST10100 from MDD（Microdiode Electronics）, in a TO-277. 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 | A | passive | Anode, the left pin of the TO-277 package, internally connected to the right pin; the schematic on page 1 shows both pins as the anode side of the diode. |
| 2 | A | passive | Anode, the right pin of the TO-277 package, internally connected to the left pin; the schematic on page 1 shows both pins as the anode side of the diode. |
| 3 | K | passive | Cathode, the bottomside heat sink of the TO-277 package, where the diode symbol points; the part is rated 100 V reverse and 10 A average forward current. |
