Procurement Notes

The STL40C30H3LL is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status updates. Designers should confirm component authenticity and storage conditions if sourcing from secondary markets, as lead times and supply continuity are not guaranteed for this specific part number.

Selection Notes

Select this component when a matched N/P-channel pair is required for half-bridge or synchronous applications within a 30V system. Ensure the design accommodates the 40A/30A current ratings and 21mΩ on-resistance constraints. Verify that the 8-PowerVDFN package dimensions fit the PCB layout and that the thermal requirements align with the 60W power dissipation rating under expected operating conditions.

Part Context

This device belongs to the STL40 series of dual MOSFET arrays from STMicroelectronics. It is part of the broader STripFET VI portfolio, which focuses on optimizing power density and switching efficiency for automotive and industrial applications. The PowerFlat packaging provides enhanced thermal performance compared to traditional DFN packages.

Replacement Considerations

As the part is discontinued, engineers must identify functional equivalents with matching voltage, current, and package specifications. Potential substitutes should be verified against the original datasheet parameters, particularly on-resistance and gate charge, to ensure circuit compatibility without redesigning the thermal or drive infrastructure.

FAQ

What is the maximum gate-source voltage for the STL40C30H3LL?

The datasheet specifies a maximum gate-source voltage (Vgs) typically limited to ±20V, though the threshold voltage is defined at 1V maximum for logic level operation.

Does the STL40C30H3LL have internal body diodes?

Yes, as a standard MOSFET array, it includes intrinsic body diodes for both the N-channel and P-channel devices, which conduct during freewheeling or dead-time periods.

What is the recommended soldering profile for the PowerFlat package?

The component supports surface mount reflow soldering. Specific thermal profiles should adhere to STMicroelectronics' recommendations for the 8-PowerVDFN package to ensure joint integrity without damaging the die.
