MDD（Microdiode Electronics） · Schottky Barrier Diodes (SBD) · TO-277
SL1045 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, left pin; connected to the same anode as the right pin per the pin diagram. |
| 2 | A | passive | Anode, right pin; connected to the same anode as the left pin per the pin diagram. |
| 3 | K | passive | Cathode, the bottom-side heat sink tab, which is the thermal pad (the datasheet's thermal-resistance test uses an 18.8 x 14.4 mm cathode pad). |
