Description
SDH SERIES CRD_Datasheet SDH SERIES CRD .
SDH series current regulative diode (CRD) is based on Silan’s planar JFET process.
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 componen
Applications
* the customers should use proper CRD according the real application environments (ambient temperature, voltage drop on CRD)
2. SDH series CRD used for LED constant-current control
Using single CRD is OK for small current (1~25 mA) as shown in figure 1. For example, three 15mA LEDs can be driven by o
