NSIC2020JBT3G (ON SEMICONDUCTOR)

The NSIC2020JBT3G is a constant current regulator & LED driver in 2 pin DO-214AA package. This 120V, 20mA 15%, 3W linear constant current regulator (CCR) is a simple, economical and robust device designed to provide a cost-effective solution for regulating current in LEDs (similar to constant current diode, CCD). The CCR is based on self biased transistor (SBT) technology and regulates current over a wide voltage range. It is designed with a negative temperature coefficient to protect LEDs from thermal runaway at extreme voltages and currents. The CCR turns on immediately and is at 45% of regulation with only 0.5V Vak. It requires no external components allowing it to be designed as a high or low-side regulator. The 120 V anode-cathode voltage rating is designed to withstand the high peak voltage incurred in A/C offline applications. The high anode-cathode voltage rating withstands surges common in industrial and commercial signage applications.
