NSI45025T1G Description

Short technical summary and product information.

The NSI45025T1G from On Semiconductor is a linear constant current regulator (CCR) designed for cost-effective current regulation in LED applications. It operates over a wide voltage range with a maximum anode-cathode voltage of 45V and provides a steady-state current of 25mA at 7.5V Vak. The device features a negative temperature coefficient to protect LEDs from thermal runaway.

 

This regulator is built on Self-Biased Transistor (SBT) technology and offers immediate turn-on with 25% regulation at only 0.5V Vak. It requires no external components and can function as a high-side or low-side regulator. The high anode-cathode voltage rating makes it suitable for surge-prone applications in automotive, industrial, and commercial signage.

 

The NSI45025T1G comes in a robust SOD-123 package, suitable for surface mount applications. It operates across a wide temperature range of -55°C to +150°C and has a power dissipation rating of 460mW. The device is Pb-Free and Halogen Free, complying with RoHS standards.
