NSI50350AST3G Description

Short technical summary and product information.

The ON Semiconductor NSI50350AST3G is a linear constant current regulator (CCR) and LED driver designed for cost-effective current regulation in LED applications. Utilizing Self-Biased Transistor (SBT) technology, it operates over a wide voltage range and includes a negative temperature coefficient to protect LEDs from thermal runaway.

 

Key electrical specifications include a 50V input voltage rating, a 350mA output current with ±10% accuracy, and a wide operating frequency range from 100 Hz to 100 kHz. The device offers immediate turn-on with only 0.5V Vak required for initial regulation.

 

Packaged in a thermally robust SMC (DO-214AB) surface-mount package, the NSI50350AST3G is suitable for high or low-side regulation. It operates across a wide temperature range of -55°C to 175°C. Typical applications include automotive lighting, AC lighting panels, display signage, and decorative lighting.

 

This device is Pb-free, halogen-free, and RoHS compliant. It is qualified to AEC-Q101 standards.
