EPC7003ASH

Overview

The EPC7003ASH is a gallium nitride (GaN) power transistor manufactured by Efficient Power Conversion (EPC). It features an enhancement-mode normally-off configuration with a drain-source breakdown voltage of 650 V and a continuous drain current rating of 12 A. The device utilizes a low-profile, leadless QFN package designed for high thermal efficiency and compact board space. Key electrical characteristics include a typical on-resistance of 140 mΩ at room temperature and a gate threshold voltage range optimized for standard logic-level drive voltages.

Feature Summary

• Enhancement-mode normally-off operation ensures safe default state without bias voltage.
• Integrated body diode provides inherent reverse conduction capability for bridge topologies.
• Low thermal resistance package design facilitates efficient heat dissipation in dense layouts.

Applications

• High-frequency DC-DC converters
• Class-D audio amplifiers
• Motor control inverters

Procurement Notes

Verify the specific suffix 'ASH' against the manufacturer's latest datasheet to confirm pinout compatibility and thermal pad specifications. Ensure the ordering code matches the exact tape-and-reel or tube packaging requirements for your assembly line. Cross-reference the date code to ensure compliance with current RoHS directives and material declarations.

Selection Notes

Select this component when designing circuits requiring high switching speeds with minimal gate charge losses. Evaluate the thermal performance under maximum load conditions to determine adequate heatsinking. Confirm that the driving circuitry can handle the fast dv/dt capabilities without inducing unwanted parasitic turn-on events in parallel devices.

Part Context

This part belongs to the EPC7000 series of GaN transistors, representing a generation of high-voltage power switches designed to replace traditional silicon MOSFETs. The series focuses on reducing system size and improving efficiency in power conversion applications through superior electron mobility and reduced switching energy losses compared to conventional semiconductor technologies.

Replacement Considerations

Direct replacements must match the 650V rating, 12A current capacity, and QFN footprint. Verify that substitute components maintain similar gate threshold voltage ranges to ensure compatibility with existing driver ICs without requiring level-shifting adjustments.
