# MMBD301-TP

**MCC Micro Commercial Components** · Schottky Diodes · SOT-23

MMBD301-TP from MCC Micro Commercial Components, in a SOT-23. 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 of the single Schottky barrier diode (30V min reverse breakdown at IR=10µA), shown as the bottom-left lead in the internal structure drawing. |
| 2 | NC | unconnected | No internal connection; the bottom-right lead in the internal structure drawing has no connection to the diode. |
| 3 | K | passive | Cathode of the single Schottky barrier diode, shown as the top lead in the internal structure drawing. |
