NSIC2050JB - Constant Current Regulator and LED Driver

1 Semiconductor Components Industries, LLC, 2014 April, 2014 Rev. 11 Publication Order Number: NSIC2050JB /DNSIC2050 JBT3 GConstant Current Regulator & LED Driver for A/C off-lineApplications120 V, 50 mA + 15%, 3 W PackageThe linear Constant Current Regulator (CCR) is a simple, economicaland robust device designed to provide a cost effective solution forregulating Current in LEDs (similar to Constant Current Diode, CCD).The CCR is based on Self Biased Transistor (SBT) technology andregulates Current over a wide voltage range. It is designed with anegative temperature coefficient to protect LEDs from thermalrunaway at extreme voltages and CCR turns on immediately and is at 20% of regulation withonly V Vak.

2 It requires no external components allowing it to bedesigned as a high or low side 120 V anode cathode voltage rating is designed to withstandthe high peak voltage incurred in A/C offline applications. The highanode cathode voltage rating withstands surges common inAutomotive, Industrial and Commercial Signage Robust Power Package: W Wide Operating Voltage Range Immediate Turn-On Voltage Surge Suppressing Protecting LEDs UL94 V0 Certified SBT (Self Biased Transistor) Technology Negative Temperature Coefficient Also available in 30 mA (NSIC2030 JBT1G) and 20 mA(NSIC2020 JBT1G) NSV Prefix for Automotive and Other Applications RequiringUnique Site and Control Change Requirements.
