CGRA4001-HF from Comchip, in a 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, indicated by the cathode band on the DO-214AC (SMA) package; the device blocks up to 50 V DC reverse voltage (VRRM 50 V for CGRA4001-HF) and passes 1.0 A average forward current. |
| 2 | A | passive | Anode of the rectifier diode in the DO-214AC (SMA) package; max instantaneous forward voltage is 1.1 V at IF=1.0 A, 25°C. |
