**MSKSEMI** · Diodes - General Purpose · SOD-323

S7116-300A from MSKSEMI, in a SOD-323. 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 | Pin1 | passive | Terminal labeled Pin1 in the circuit diagram; the datasheet does not state whether it is the anode or cathode, and the device limits are VR 40 V DC, VRM 45 V repetitive peak, and Io 1 A average rectified forward current. |
| 2 | Pin2 | passive | Terminal labeled Pin2 in the circuit diagram; the datasheet does not state whether it is the anode or cathode, and the device limits are VR 40 V DC, VRM 45 V repetitive peak, and Io 1 A average rectified forward current. |
