EPC8004 Enhancement Mode Power Transistor

Transcription

1 Enhancement Mode Power Transistor, V R DS(on), mω, A G D S EFFICIENT POWER CONVERSION HAL Gallium Nitride is grown on Silicon Wafers and processed using standard CMOS equipment leveraging the infrastructure that has been developed over the last years. GaN s exceptionally high electron mobility and low temperature coefficient allows very low R DS(on), while its lateral device structure and majority carrier diode provide exceptionally low Q G and zero Q RR. The end result is a device that can handle tasks where very high switching frequency, and low on-time are beneficial as well as those where on-state losses dominate.
