GOODWORK · Switching Diodes · SOT-23
KA2-MMBD4148 from GOODWORK, 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 switching diode (MMBD4148:KA2); the symbol shows the diode triangle pointing from pin 1 toward pin 3, with 100 V reverse voltage and 300 mA forward continuous current ratings. |
| 2 | NC | unconnected | No internal connection; the KA2 single-diode symbol shows no element attached to pin 2. |
| 3 | K | passive | Cathode of the single switching diode (MMBD4148:KA2), the top pin of the SOT-23 package, with 100 V DC blocking voltage (VR). |
