Current Limiting Diodes A CURRENT LIMITING DIODE, CLD, also known as a "Current Regulating Diode" or a "Constant Current Diode" performs quite a unique function.  Similar to a zener diode, which regulates voltage at a particular current, the CLD limits or regulates current over a wide voltage range.   The CLD is diffused using a "Field Effect" process similar to the diffusion techniques used for manufacturing JFETs with the electrical characteristics optimized for high output impedance and current regulating capability.                  Available in a wide range of voltage and current ratings, and offered in  a variety of leaded and surface mount package styles, the CLD provides an alternative to conventional design techniques for controlling current, especially when reliability and component density are prime considerations.
