SuperGaN TP65H300G4LSG TP65H035G4WS

Transphorm, the GaN specialist, is sampling  a new slate  of parts which it calls its 4th generation or SuperGaN.

The first JEDEC-qualified SuperGaN device will be the TP65H300G4LSG, a 240 mΩ 650 V GaN FET in a PQFN88 package.

The second SuperGaN device is the TP65H035G4WS, a 35 mΩ 650 V GaN FET in a TO-247 package.

These devices are currently sampling and will be available Q2 and Q3 respectively.

Target applications include adapters, servers, telecommunications, broad industrial, and renewables.

System designers can assess the technology in Transphorm’s 4 kW bridgeless totem pole AC-DC evaluation board, the TDTTP4000W066C-KIT (see below).

SuperGaN benefits include:

Increased Performance: Gen IV provides a flatter and higher efficiency curve with an improved Figure of Merit (RON*QOSS) of approximately 10 percent.

Easier Designability: Gen IV offers increased simplicity of design-in by removing the need for a switching node snubber at high operation currents.

Enhanced Inrush Current Capability (di/dt): Gen IV removes the switching current limits for the built-in freewheeling diode function in half bridges.

Reduced Device Cost: Gen IV's design innovations and patented technology simplify device assembly.The resulting cost adjustments continue to bring Transphorm’s GaN closer to Silicon transistor pricing.

Proven Robustness/Reliability: Gen IV’s 35 mΩ FET offers the same gate robustness of +/- 20 Vmax and noise immunity of 4 V that is currently delivered by Transphorm's Gen III devices.
