(Editor’s note: check out the full article, “The fundamental advantages of D-Mode GaN in cascode configuration,” and get the full technical story behind these “busted” myths.) Reality: When switching from reverse conduction to off-state, the reverse recovery charge accounts for not only bipolar transport minority carriers recombination but also the formation of the space-charge region, […]

MYTH #3: Cascode GaN oscillates.
(Editor’s note: check out the full article, “The fundamental advantages of D-Mode GaN in cascode configuration,” and get the full technical story behind these “busted” myths.) Reality: Cascode GaN has a lot of gains. And gain is a wonderful thing, leading to very fast switching. It needs, however, to be harnessed properly to achieve the […]
MYTH #1: Si MOSFETs add on-state resistance and reverse recovery charge
(Editor’s note: check out the full article, “The fundamental advantages of D-Mode GaN in cascode configuration,” and get the full technical story behind these “busted” myths.) Reality: In cascode GaN technology, the GaN chip bears most of the off-state high voltage (> 90%). The Si MOSFET needs only to bear a few 10s of volts. […]
The fundamental advantages of D-Mode GaN in cascode configuration
Inarguably, GaN power semiconductors are a hot topic in power electronics. Two transistor variations prevail today: cascode GaN and e-mode GaN. When confronted with the choice, the debate at times inexplicably leans toward e-mode. In reality, cascode GaN proves to be a fundamentally superior platform in performance, reliability, versatility, manufacturability, and practical application. The reasoning […]
Integrated GaN system-in-package to showcase at APEC
Transphorm, Inc. and Weltrend Semiconductor Inc. announced the release of their first GaN System-in-Package (SiP). The WT7162RHUG24A is an integrated circuit designed for use in 45 to 100-watt USB-C PD power adapters charging smartphones, tablets, laptops, and other smart devices. It offers peak power efficiency of greater than 93%. Device samples will be available in […]
