MMBD4148CC-6AF from FOSAN, 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 | A1 | passive | Anode of the first diode; the two diodes share a common cathode on pin 3, with VRRM/VR rated 100 V and IF(IO) 200 mA per the datasheet. |
| 2 | A2 | passive | Anode of the second diode; the two diodes share a common cathode on pin 3, with VRRM/VR rated 100 V and IF(IO) 200 mA per the datasheet. |
| 3 | K | passive | Common cathode of both diodes (marking D5), with peak forward current IFM of 300 mA and reverse recovery time Trr of 4 nS max. |
