The EPC21603ENGRT is a GaN power transistor from Efficient Power Conversion (EPC). It features a 100 V drain-source voltage and a typical on-resistance of 1.8 mΩ. The device utilizes an enhanced mode (e-mode) normally-off architecture, ensuring safe operation without negative gate bias. Packaged in a compact 4x5 mm QFN-16 footprint, it supports high-frequency switching applications with low thermal resistance.
Verify the specific suffix 'ENGRT' indicates the tape-and-reel packaging configuration. Confirm the manufacturer is Efficient Power Conversion Corporation to distinguish from other entities using the EPC acronym. Ensure the datasheet matches the 100V rating and QFN-16 package dimensions before procurement.
Select this component for designs requiring high efficiency at frequencies above 1 MHz. Evaluate the thermal performance based on the PCB copper area requirements specified in the thermal resistance parameters. Ensure the gate drive voltage does not exceed the maximum rated limits defined in the absolute maximum ratings section.
This part belongs to the EPC21xx series of enhancement-mode gallium nitride transistors. These devices are designed to replace silicon MOSFETs in high-performance power conversion systems. The series emphasizes reduced switching losses and improved thermal management compared to traditional semiconductor technologies.
Direct pin-to-pin replacements may include other eGaN FETs from the same manufacturer with similar voltage ratings. Verify that any substitute maintains the same package outline and thermal characteristics to ensure compatibility with existing PCB layouts.
