NIS5112D1R2G

Current Regulation/Management Overview

The NIS5112D1R2G is a single-channel electronic fuse manufactured by onsemi, designed for overcurrent and short-circuit protection in power distribution networks. It integrates a PPTC (Polymeric Positive Temperature Coefficient) element within an SOIC-8 surface-mount package, measuring 5 x 4 x 1.5 mm. The device operates across a temperature range of -40 °C to +175 °C, ensuring reliability in demanding environments. As a self-resetting fuse, it provides robust circuit safeguarding without requiring manual intervention after fault clearance.

Current Regulation/Management Feature Summary

• Integrates a self-resetting PPTC element for automatic recovery following fault conditions
• Provides single-channel overcurrent and short-circuit protection
• Engineered for high-temperature operation up to +175 °C

Current Regulation/Management Applications

• Power distribution protection in industrial systems
