The TPH3206PS is a 600V EZ-GaN™ HEMT for high frequency operation from Transphorm. Manufactured by Fujitsu and assembled in a TO220 package, it features the Quiet-TabTM scheme, which increases switching speed.
The TPH3206PS combines a normally-on GaN-on-Silicon HEMT, which withstands high voltages, and a standard low voltage MOSFET, which drives high frequency, in a cascode configuration that ultimately yields a normally-off transistor.
Based on a complete teardown analysis, the report also provides an estimation of the production cost of the package, HEMT, MOSFET and resistor.
The report also proposes a comparison with the GaN Systems GS66504B 650V HEMT. This comparison highlights the huge differences in design and manufacturing process and their impact on device size and production cost.
