Central Semiconductor CDCLD Current Regulator Diodes

Central Semiconductor CDCLD Current Regulator Diodes are specifically designed for applications requiring constant current regulation. These diodes are designed with a unique process that maintains a constant current over a broad temperature range. The zero temperature coefficient feature eliminates the need for additional resistors to compensate for variation in the current limit that results from changes in temperature. The regulator current values range from 27.5mA to 575mA with a maximum limiting voltage (VL) ranging from 1.5V to 2V. These current regulator diodes are optimized for heat dissipation and offer nominal current regulation at low voltage input.

The CDCLD current regulator diodes are manufactured in the industry-standard DPAK surface mount package and are RoHS and REACH compliant. These current regulator diodes are operated and stored at -55°C to 150°C temperature range. Typical applications include high-intensity lighting systems, infrastructure lighting systems, LED drivers, light dimming systems, and test/measurement equipment.
