MMBD1505A from onsemi, 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 | K1 | passive | Cathode of diode 1 in the dual common-anode MMBD1505A, with 200 V maximum repetitive reverse voltage and 200 mA average rectified forward current per the datasheet ratings. |
| 2 | K2 | passive | Cathode of diode 2 in the dual common-anode MMBD1505A, with 200 V maximum repetitive reverse voltage and 200 mA average rectified forward current per the datasheet ratings. |
| 3 | A | passive | Common anode of both diodes in the MMBD1505A, joined internally to the anodes of diodes 1 and 2. |
