NV6513

Overview

The NV6513 is a 650V enhancement-mode gallium nitride field-effect transistor (GaN FET) manufactured by Navitas Semiconductor. It utilizes GaNFast technology to deliver high switching speeds and low on-resistance within a compact package. The device features an integrated Kelvin source connection for accurate gate drive sensing, which minimizes parasitic inductance effects during switching transitions. This architecture supports efficient operation in hard-switching and soft-switching topologies, enabling reduced system size and improved thermal performance in power conversion applications.

Feature Summary

• Integrated Kelvin source connection for precise gate drive control
• Enhancement-mode normally-off operation for simplified driving
• High switching speed with low output capacitance
• Robust avalanche capability for enhanced reliability

Applications

• AC-DC and DC-DC power converters
• Power factor correction (PFC) circuits
• Class-D audio amplifiers
• Inductive heating systems

Procurement Notes

Verify the specific suffix code on the component marking to confirm the exact package variant and tape-and-reel configuration. Ensure that the ordering information matches the required lead time and compliance standards such as RoHS. Cross-reference the manufacturer's latest datasheet to confirm availability of the specific batch and any recent design revisions.

Selection Notes

Select this component for designs requiring high power density and efficiency at 650V. Evaluate the gate drive requirements against the device's threshold voltage and charge characteristics. Consider the thermal management needs based on the package's power dissipation capabilities and the intended switching frequency. Ensure the PCB layout supports the Kelvin source connection for optimal performance.

Part Context

The NV6513 belongs to Navitas Semiconductor's GaNFast family of power switches. This series integrates the GaN HEMT die with a dedicated driver IC to simplify system design. Compared to traditional silicon MOSFETs, these devices offer superior switching performance and reduced conduction losses, making them suitable for next-generation high-frequency power supplies.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the unique integration of the driver. Verify compatibility with existing gate drive circuits when substituting with other 650V GaN FETs. Check if alternative packages from the same manufacturer offer similar electrical characteristics and thermal profiles.
