CMJD5750 TR

Current Regulation - Diodes, Transistors Overview

The Central Semiconductor CMJD5750 TR is a surface mount silicon field effect current regulator diode housed in the low profile DFN123F epoxy molded case. It provides constant current regulation over a wide voltage range with a nominal regulator current of 5.75 mA at VT=25V. The device supports a peak operating voltage of 100 V and dissipates up to 445 mW at 25°C, extending to 780 mW when mounted on a 300mm² four-layer PCB with two-ounce copper traces. Operating temperatures range from -65°C to +150°C. Electrical characteristics include a minimum dynamic impedance of 0.05 MΩ and a maximum limiting voltage of 4.5 V.
