NCV8406STT3G

Overview

The NCV8406STT3G is a single-channel, N-Channel SmartFET power switch manufactured by onsemi. It integrates an enhancement-mode MOSFET with diagnostic and protection features in a SOT-223-4 surface-mount package. Key electrical parameters include a drain-source breakdown voltage (Vds) of 65 V, a continuous drain current (Id) of 7 A, and a maximum on-resistance (Rds(on)) of 210 mΩ. The device operates within a temperature range of -40°C to +150°C, supports a gate-source voltage (Vgs) of ±14 V, and dissipates up to 1.25 W of power. It is qualified under the AEC-Q100 standard for automotive reliability.

Feature Summary

• Integrates overcurrent, overtemperature, and short-circuit protection mechanisms within a single channel.
• Provides diagnostic feedback capabilities through integrated sensing outputs.
• Features low on-resistance for efficient power distribution in compact designs.
• Qualified for automotive applications ensuring high reliability under harsh conditions.

Applications

• Automotive lighting control systems
• Power distribution units in vehicle electronics
• High-side load switching for accessory modules

Procurement Notes

Verify the specific suffix 'STT3G' against the manufacturer's official datasheet to confirm packaging type and reel quantity specifications. Ensure the component meets AEC-Q100 requirements if deployed in automotive environments. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when a robust, single-channel high-side switch is required for loads up to 7 A. The 65 V rating suits 12 V automotive systems with transient spikes. Consider the SOT-223-4 package for thermal management needs and board space constraints. Verify that the integrated protection features align with the system's safety architecture requirements.

Part Context

This part belongs to the NCV8406A series of SmartFETs from onsemi, designed for automotive power distribution. It complements other devices like the NCV8406ASTT1G, differing primarily in packaging or tape-and-reel quantities. The series targets applications requiring integrated protection and diagnostics in a small form factor.

Replacement Considerations

The NCV8406ASTT1G is a verified substitute within the same family, offering identical electrical characteristics. Confirm pinout compatibility and thermal performance before substitution. Other NCV8406 variants may differ in packaging; verify mechanical fit and soldering profiles.
