MMBD452LT1G 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 | ANODE | passive | Anode of the first diode of the dual hot-carrier (Schottky barrier) pair; the datasheet's device reverse voltage rating is VR = 30 V (each diode). |
| 2 | CATHODE | passive | Cathode of the second diode of the dual pair; the datasheet's device reverse voltage rating is VR = 30 V (each diode). |
| 3 | CATHODE/ANODE | passive | Common connection of the two diodes, shown as cathode-anode on the datasheet's style drawing; the datasheet's device reverse voltage rating is VR = 30 V (each diode). |
