ACURA107-HF from Comchip, in a DO-214AC(SMA). 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 | K | passive | Cathode, marked by the cathode band on the DO-214AC (SMA) package; rated for 1000 V maximum repetitive peak reverse voltage and 1.0 A average forward current. |
| 2 | A | passive | Anode terminal of the ultra fast recovery rectifier diode, with 1.7 V maximum forward voltage at IF=1.0 A. |
