NSI45030ZT1G Description

Short technical summary and product information.

The On Semiconductor NSI45030ZT1G is a linear constant current regulator (CCR) designed for cost-effective current regulation in LED applications. Utilizing Self-Biased Transistor (SBT) technology, this device 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 and a steady-state output current of 30mA at 7.5V. The accuracy of the current regulation is within ±15%. The device is designed for immediate turn-on and requires no external components, allowing for flexible high or low-side regulation.

 

Packaged in a robust SOT-223 (TO-261) surface-mount package, the NSI45030ZT1G is suitable for applications requiring a power dissipation of up to 1.4 Watts. Its high anode-cathode voltage rating makes it resilient to surges common in automotive, industrial, and commercial signage applications. The device is AEC-Q101 qualified and UL94-V0 certified, ensuring reliability and safety.

 

This constant current regulator is ideal for various applications including LED backlighting for automotive clusters and displays, AC lighting panels, decorative lighting, and channel lettering. Its robust design and protective features make it a reliable choice for demanding environments.
