Changjing · Electrostatic And Surge Protection (TVS/ESD) · SOD-123FL
CJSMF64CA from Changjing, in a SOD-123FL. 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 | A1 | passive | Bi-directional TVS terminal (no polarity, no cathode band) with 64 V reverse standoff, 71.39-78.54 V breakdown at 1 mA, and 102 V max clamping at 2 A peak pulse current. |
