NIF62514T1G

Overview

The NIF62514T1G is a self-protected power distribution switch featuring an N-channel MOSFET with a 40V drain-source voltage rating and a continuous current capacity of 6A. It integrates temperature and current limiting protection mechanisms within a SOT-223 (TO-261) surface-mount package. The device operates with a gate threshold voltage of 1.7V and exhibits an on-resistance of 0.09 ohms at a 10V gate drive, ensuring efficient power handling in compact designs.

Feature Summary

• Integrated self-protection against over-temperature and over-current conditions
• N-channel MOSFET architecture for low-loss power switching
• Low gate threshold voltage enabling compatibility with standard logic levels

Applications

• Power distribution networks requiring integrated fault protection
• Load driver circuits in industrial control systems
• Battery management systems needing short-circuit and thermal safeguards

Procurement Notes

Verify the specific suffix T1G to confirm tape-and-reel packaging configuration as indicated by manufacturer documentation. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the datasheet revision date to confirm alignment with current design specifications before finalizing orders.

Selection Notes

Select this component when a compact solution combining high-side switching with inherent thermal and current limiting is required. The 40V rating suits low-voltage DC applications, while the 6A capability supports moderate load currents. Consider the SOT-223 package for PCB space constraints where adequate thermal dissipation can be managed through board copper area.

Part Context

This part belongs to onsemi's family of self-protected FETs designed for robust power management. Unlike standard discrete MOSFETs, it embeds control logic for protection features directly alongside the power transistor. This integration reduces external component count and simplifies layout compared to implementing separate protection circuits with discrete switches.

Replacement Considerations

Direct substitutes must match the 40V/6A rating, N-channel type, and SOT-223 package. Verify that alternative parts include equivalent integrated temperature and current limiting functions rather than bare MOSFETs. Check pinout compatibility to ensure seamless replacement without circuit redesign.
