EPC2031

Overview

The EPC2031 is an enhancement mode Gallium Nitride (GaN) field-effect transistor manufactured by Efficient Power Conversion. It features a 100 V drain-to-source voltage rating and a continuous drain current of 48 A at 25°C ambient temperature with a thermal resistance of 3°C/W. The device exhibits a maximum on-resistance of 10 mΩ. Packaged as a bumped die in an uncase configuration, it utilizes lateral GaN technology grown on silicon wafers to achieve low gate charge and zero reverse recovery charge.

Feature Summary

• Lateral GaN structure provides exceptionally low gate charge and zero reverse recovery charge for high-speed switching
• Enhancement mode operation allows direct drive compatibility with standard control logic
• Bumped die package facilitates efficient thermal dissipation and integration into power modules

Applications

• High-frequency DC-DC converters
• Class D audio amplifiers
• Power inverters
• Wireless power transfer systems

Procurement Notes

Verify the specific suffix or variant code against the manufacturer's official datasheet to ensure correct electrical ratings and pinout configuration. Confirm that the procurement channel sources genuine components from Efficient Power Conversion or authorized distributors to avoid counterfeit devices. Check for RoHS compliance status and moisture sensitivity level requirements before finalizing orders.

Selection Notes

Select this component for designs requiring high switching frequencies and reduced passive component size due to low parasitic capacitances. Ensure the application circuit includes appropriate gate driving capabilities compatible with enhancement mode GaN FETs. Evaluate thermal management strategies carefully, as the device performance depends heavily on the junction-to-ambient thermal resistance provided by the PCB layout.

Part Context

This part belongs to the EPC eGaN FET family, which leverages silicon wafer infrastructure for manufacturing. These transistors are designed to replace traditional silicon MOSFETs in applications demanding higher efficiency and power density. The lateral device structure distinguishes them from vertical GaN technologies, offering specific advantages in switching speed and body diode characteristics.

Replacement Considerations

Direct replacements within the same family include EPC2022, EPC2024, and EPC2033. Verify that substitute parts match the required voltage and current ratings. Note that pin configurations and thermal characteristics may vary between different die packages within the series.
