JUXING · Electrostatic And Surge Protection (TVS/ESD) · SMC
SMCJ7.0A from JUXING, in a SMC. 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 | Cathode | passive | Cathode terminal of the unidirectional SMCJ7.0A TVS (1500W 10/1000µs peak pulse power, stand-off voltage 7V); connect to the protected positive line. |
| 2 | Anode | passive | Anode terminal of the SMCJ7.0A TVS, normally connected to ground; for bipolar versions the two terminals are interchangeable. |
