Current Regulating Devices

  • Semitec CRD (Current Regulating Device) is a diode which supplies constant current to an electrical circuit, even with power supply fluctuations or load impedance fluctuations. CRD is used for current stabilization and/or current limiting. They are offered in glass diode and surface mount configurations.


  • CRD

    Semitec CRD is a diode which supplies a constant current to an electrical circuit. They allow a current through them to rise to a certain value, and then level off at a specific value. Unlike Zener diodes, the CRD keeps the current constant instead of the voltage constant. These devices keep the current flowing through them unchanged when the voltage changes or when impedance fluctuations occur. CRDs are used for current stabilization and current limiting.
