• Similar to a Zener diode, which regulates voltage at a particular current, the CRD limits or regulates current over a wide voltage range. Due to this property, it is a simple, economical and robust device designed to provide a cost effective solution for regulating current in LEDs. Available in a wide range of voltage and current ratings, and offered in a variety of through-hole and surface mount package styles, the CRD provides an alternative to conventional design techniques for controlling current, especially when reliability and component density are prime considerations.
