Overview
The NSV45060JDT4G is an adjustable constant current regulator (CCR) and LED driver produced by onsemi. This device is designed to provide a cost-effective solution for regulating current in LEDs, similar to a Constant Current Diode (CCD). It is based on Self-Biased Transistor (SBT) technology and regulates current over a wide voltage range. The CCR is known for its immediate turn-on and ability to protect LEDs from thermal runaway due to its negative temperature coefficient. It is available in a thermally robust DPAK package and is qualified to the stringent AEC-Q101 standard, making it suitable for automotive, industrial, and commercial applications.
