Ansas Semiconductor specializes in the manufacture of high-performance rectifiers, Schottkys, suppressor diodes and Mosfets. The company offers a new family of current limiting diodes (CLD) in a space-saving SOD-123 housing, which is particularly suitable for controlling price-sensitive LED applications such as furniture, decor and background lighting.

The new CLD diodes control the forward current over the specified voltage range and keep the current constant. Therefore, these components are very well suited, for example, to control LEDs on a variable voltage source with constant current. Depending on the type, the voltage range extends from 2.5V to a maximum of 190V with forward currents of up to 44mA.

Due to the linear correlation between the diode forward current and the brightness of the LED, it is possible to control the operating point of the LED very precisely and easily using only the CLD and a few external components. For increased power requirements, it is possible to operate several CLDs in parallel configuration. This simple circuit offers the end user a multitude of possibilities to realize compact, reliable and competitive LED solutions.
