SDH SERIES CRD
DESCRIPTION
SDH series current regulative diode (CRD) is based on Silan’s planar JFET process.
It features low start-up stabilized current supply voltage, stable constant-current characteristics and high forward breakdown voltage for its advanced process and smart design.
SDH series CRD has powerful anti-interference capacity of surge current between the anode and cathode, and no other assistant components are needed in application.
SDH series CRD supplies constant current to an electric circuit and is widely used in the constant-current LED driver, modules in phone circuitry, etc.
It is available in SOD-123, SOT-223-3L and TO-92-3L packages.
FEATURES
∗ Low start-up stabilized current supply voltage ∗ High dynamic impedance ∗ Constant-current range: 1mA-40mA. ∗ Be paralleled for current extension. ∗ Negative temperature coefficient for LED protection under
high temperature
