NSIC2030BT3G

Current Regulation/Management Overview

The NSIC2030JBT3G is a linear constant current regulator from onsemi, designed for LED applications. It utilizes Self-Biased Transistor (SBT) technology to provide stable current regulation without external components. The device operates in AC offline environments with a maximum anode-cathode voltage of 120V and supports a driver current of 30mA. It features PWM dimming capability and delivers up to 3W of power. The component is available in surface-mount packaging and offers five output configurations.

Current Regulation/Management Feature Summary

• Utilizes Self-Biased Transistor (SBT) technology for precise current regulation across wide voltage ranges.
• Provides immediate turn-on response, achieving significant regulation at low anode-cathode voltages.
• Incorporates negative temperature coefficient characteristics to prevent thermal runaway in LEDs.
• Features robust voltage surge suppression to protect LEDs in automotive and industrial environments.

Current Regulation/Management Applications

• Automotive side mirror markers
• Instrument cluster backlighting
• High-mounted stop lamps (CHMSL)
• Interior reading lights

Current Regulation/Management Procurement Notes

Verify the exact part number suffix against official documentation, as variations such as 'NSIC2030JBT3G' or 'NSVC2030JBT3G' exist within the manufacturer's portfolio. Ensure the selected variant matches the required application specifications, particularly regarding AEC-Q101 certification and PPAP capabilities for automotive use cases. Confirm package type and compliance standards prior to ordering.

Current Regulation/Management Selection Notes

Select this component for designs requiring simple, cost-effective LED current regulation without complex external circuitry. It is suitable for applications needing high reliability under varying voltage conditions and thermal stress. Consider the 30mA current rating and 120V voltage limit when sizing the LED string. Evaluate the need for automotive-grade qualification if deploying in vehicle systems.
