Constant Current Diodes

A constant current diode also called a current limiting diode (CLD), is an electronic device that regulates or limits current to a maximum value. This is important as it protects your circuit from harmful effects in the event of a short-circuit.

How do constant current diodes work?

Constant current diodes are made from a junction field-effect transistor, the simplest...
