CDSQC4148-HF from Comchip, in a 0402. 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 | K | passive | Cathode; identified by the cathode band on the package; repetitive peak reverse voltage VRRM = 100 V, reverse voltage VR = 75 V, reverse current IR = 25 nA max at VR = 20 V / 2.5 µA max at VR = 75 V. |
| 2 | A | passive | Anode; average forward current IO = 150 mA, surge peak forward current IFSM = 4 A (Tp=1 µs) / 1 A (Tp=1 ms), forward voltage VF = 1.0 V max at IF = 50 mA DC. |
