SMMBD7000LT1G from onsemi, in a SOT-23-3. 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 terminal of one diode in the dual switching diode; each diode is rated for 100 V reverse voltage and 200 mA forward current. |
| 2 | CATHODE | passive | Cathode terminal of the other diode in the dual switching diode; per-diode maximum ratings are 100 V reverse voltage and 200 mA forward current. |
| 3 | CATHODE/ANODE | passive | Common terminal shared by both diodes (labelled CATHODE-ANODE in Style 11); the datasheet gives no separate limit for this pin beyond the per-diode maximum ratings. |
