RCLAMP1221PW.C from SEMTECH, in a DFN1006-2. 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 | Pin 1 | passive | Pin 1 is marked by a bar on the package and is the reference for pin 1 location; the device is electrically symmetrical and protects one line with a 12 V reverse stand-off voltage (VRWM) and a 0.45 pF maximum junction capacitance at VR = 0 V. |
| 2 | 2 | passive | Pin 2 is the other terminal of the 2-lead DFN package; the device is electrically symmetrical, rated for 12 V working voltage and 4 A peak pulse current (tp = 8/20 µs). |
