Main application:  simplest LED driver for LED arrays power supply regulation designed for lightening, buildings decorative lightening and automotive lightening. 

SC “VSP-Mikron” designed a die series of current regulator diodes with the following technical characteristics: 

•  nominal value of pinch-off current: Ip=20mA, 30mA, 40mA, 50mA, 60mA;

•  maximum variation of pinch-off current:  +/-10%;

•  breakdown voltage: Vb=50V, 100V;

•  typical voltage value wherein CRD switches to stabilization mode: Vk= 3-4V 

View of current-voltage characteristics and basic parameters of CRD. 

 Ip – nominal value of pinch-off current, measured at 10V,

 Vs – maximum stabilizing voltage, i.e. maximum voltage wherein the following ratio is carried out: I(Vs)/I(10V)<1,15,

 Vk –  turnover voltage, i.e. the voltage wherein the current proceeding via CRD is equal to 0,8Ip.(80% of the nominal),

 Vb – breakdown voltage.

At consecutive inclusion in a power-supply circuit CRD provides nominal rate of current in the wide range of voltage from 3V to 100V.
