MMBD1503A from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of single small-signal diode; max average rectified forward current 200 mA, peak surge 1.0 A (1 s). |
| 2 | NC | unconnected | No connect - pin is not internally bonded for the MMBD1503A single-diode configuration. |
| 3 | K | passive | Cathode of single small-signal diode; maximum repetitive reverse voltage VRRM = 200 V, reverse current IR ≤ 10 nA at VR = 180 V (25 °C). |
