The NSI45020AT1G is a compact, high-reliability constant-current regulator (CCR) IC from onsemi designed for LED-drive and general current-regulation applications. Packaged in a SOD-123 surface-mount form and rated for input voltage up to 45 V, it delivers a steady output current of ~20 mA with ±10% accuracy. It requires no external components, features self-biased transistor technology with a negative temperature coefficient for LED protection, and is qualified for automotive/industrial (AEC-Q101) applications. With this part, your procurement portfolio supports compact, cost-effective LED and indicator solutions for global electronic systems.

Top Reasons to Choose the Onsemi NSI45020AT1G LED Driver IC:

This LED driver IC provides a true constant-current solution (20 mA) in a minimal two-lead SOD-123 package, simplifying PCB layout and BOM.
Wide input voltage tolerance (0-45 V) and high thermal range (-55 °C to +150 °C) ensure suitability for harsh/industrial lighting or signalling applications.
Onsemi brand credibility, AEC-Q101 qualification, RoHS/halogen-free compliance and reliable supply-chain traceability align with Enrgtech’s sourcing standards.

Functional Highlights of the NSI45020AT1G:

Output current: 20 mA nominal (±10%).
Input (anode-cathode) voltage rating up to 45 V.
SOD-123 package, 2-lead surface-mount.
Operating temperature range: –55 °C to +150 °C.
Negative temperature coefficient for LED protection (reduces current as temp rises).
