CMJA5050 Current Limiting Diodes Central Semiconductor CMJA5050 Current Limiting Diodes (CLDs) are developed for adjustable current regulation from 50mA to 80mA. These diodes operate at -65°C to 150°C temperature range and provide 50V of peak operating voltage. The CMJA5050 diodes are used in applications such as LED lighting and displays, AC lighting panels, negative temperature coefficient for LED protection, and measurement equipment.
