JED523-5V

Shenzhen JDT Fuse · ESD Protection Devices · SOD-523

JED523-5V from Shenzhen JDT Fuse, in a SOD-523. 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 1 passive Protected data or power line pin (cathode side), measured as Pin 1 to Pin 2 for the 5V reverse working voltage, breakdown voltage and clamping voltage (IPP=8A, 8x20μs) specifications.
2 2 passive Return/ground-side pin (anode side) of the single-line ESD protector, with forward voltage specified from Pin 2 to Pin 1 at IF=10mA.
