PMBD7100 from Nexperia, 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 high-speed switching diode; the device has a continuous reverse voltage of max. 100 V and a repetitive peak forward current of max. 450 mA. |
| 2 | a2 | passive | Anode of the second high-speed switching diode; the device has a continuous reverse voltage of max. 100 V and a repetitive peak forward current of max. 450 mA. |
| 3 | common connection | passive | Common connection of the two diodes, which the datasheet describes as common cathodes; the diodes switch at max. 4 ns. |
