NCV8403ASTT3G

Overview

The NCV8403ASTT3G is a self-protected low-side power distribution IC from onsemi, designed for automotive and industrial applications. It features an N-channel MOSFET with a maximum continuous current of 6 A and a typical on-resistance of 90 mOhms. The device supports a load voltage up to 42 V and operates within a junction temperature range of -40°C to 150°C. Key protection mechanisms include fixed current limiting, overtemperature shutdown, and overvoltage protection, all integrated into a compact SOT-223 (TO-261) surface-mount package.

Feature Summary

Integrates self-protection features including fixed current limiting, overtemperature shutdown, and overvoltage protection for robust load management.
Features a low on-resistance N-channel MOSFET optimized for efficient power distribution in low-side switching configurations.
Complies with AEC-Q101 qualification standards, ensuring reliability for demanding automotive electronic environments.

Applications

Automotive lighting systems
Power distribution units in vehicles
Industrial load switching

Procurement Notes

Verify the specific suffix 'TT3G' against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and orientation. Ensure the component meets AEC-Q101 grade requirements for your target application. Cross-reference the ordering part number with the latest onsemi documentation to avoid discrepancies in pinout or thermal characteristics.

Selection Notes

Select this component for low-side switching applications requiring high current capacity up to 6 A. Consider the 90 mOhms typical on-resistance for efficiency calculations. The wide operating temperature range and automotive qualification make it suitable for harsh environments where standard commercial parts may fail.

Part Context

This part belongs to the NCV8405A/NCV8403A family of self-protected power switches. It shares similar protection logic and interface characteristics with other members of the series but differs in current handling capabilities and on-resistance values. The family is designed to simplify power distribution design by integrating control and protection functions.

Replacement Considerations

Direct replacements within the same package and functionality include NCV8405ASTT3G, which offers higher current capability. Verify compatibility with existing PCB layouts and thermal constraints when substituting components with different on-resistance or current ratings.
