NSI45030T1G Description

Short technical summary and product information.

The ON Semiconductor NSI45030T1G is a linear constant current regulator (CCR) designed for cost-effective current regulation in LED applications. Utilizing Self-Biased Transistor (SBT) technology, it operates over a wide voltage range and features a negative temperature coefficient to protect LEDs from thermal runaway.

 

Key electrical specifications include a maximum anode-cathode voltage of 45V, a typical output current of 30mA at 7.5V Vak, and an accuracy of ±15%. The device has a power dissipation rating of 460mW.

 

Designed for robustness, the NSI45030T1G is qualified to AEC-Q101 standard and comes in a thermally robust SOD-123 package. It supports both high-side and low-side regulation and requires no external components. Its high anode-cathode voltage rating makes it suitable for automotive, industrial, and commercial signage applications.

 

This regulator is Pb-free, halogen-free, BFR-free, and RoHS compliant. It is surface-mounted and ideal for applications such as automotive backlighting, display signage, and decorative lighting.
