NSI45035JZT1G Description

Short technical summary and product information.

The ON Semiconductor NSI45035JZT1G is an adjustable constant current regulator (CCR) IC based on Self-Biased Transistor (SBT) technology. It provides a cost-effective solution for regulating current in LEDs, functioning similarly to a Constant Current Diode (CCD).

 

This device operates over a wide voltage range with a maximum input voltage of 45V and can regulate current up to 70mA with ±15% accuracy. It features immediate turn-on and a negative temperature coefficient to protect LEDs from thermal runaway. The adjustable current feature allows for customization by attaching a resistor to the Radj pin.

 

The NSI45035JZT1G is housed in a robust SOT-223 (TO-261) surface-mount package, capable of dissipating up to 1.5 Watts. Its high anode-cathode voltage rating makes it suitable for applications with voltage surges, common in automotive and industrial environments. The device is AEC-Q101 qualified and RoHS compliant.

 

Key applications include LED backlighting for automotive clusters and displays, signage, and decorative lighting. Its simple, no-external-component design makes it ideal for high or low-side regulation.
