Transphorm transforms its GaN-on-silicon power portfolio

The new devices include PQFN-packaging and smaller die sizes targeting smaller, low-power applications

Transphorm has announced what it says is the industry’s first 600V GaN-based low-profile PQFN products and the expansion of its product portfolio in the industry-standard TO220 packages.

This follows the introduction of its GaN-on-silicon transistor family at the APEC 2013 trade show JEDEC-qualified 600V GaN device platform.

Transphorm’s 600V GaN HEMTs (high electron mobility transistors) utilise the company’s patented, EZ-GaN technology that combines low switching and conduction losses, reducing the overall system energy dissipation up to 50 percent compared with using conventional silicon-based power conversion designs.

The new PQFN products, feature 290 mΩ RDSON 29 nC Qrr and low inductance for high-frequency switching capability. The PQFN88-packaged LD devices also feature a Kelvin connection to better isolate the gate circuit from the high-current output circuit to further reduce EMI.

In addition, the TPH3002PD and TPH3002PS GaN HEMTs have been released for use in smaller, lower power applications such as adapters and all-in-one computer power supplies. These devices also feature 290 mΩ RDSON 29 nC Qrr and high- frequency switching capability.

The devices were introduced at APEC 2014.

“Every year since 2011 we have announced new advancements of our GaN technology at this major tradeshow - and this year is no exception,” says Primit Parikh, President of Transphorm.

“Now by introducing the industry’s first qualified 600V GaN PQFN-packaged products, we have increased the types of applications where GaN can enable dramatically more efficient, compact and low-cost solutions.This dispels the widespread misconception that GaN isn’t ready for prime-time.Once again we’ve shown GaN products are available today and are actually being used in a multitude of real-world applications.”

The TO220-packaged TPH3002PD and TPH3002PS and the PQFN-packaged TPH3002LD and TPH3002LS are available for sale to qualified customers worldwide, directly or through Transphorm’s distribution channels.

The evaluation boards are also available with the 600V TO220 GaN HEMT devices in configurations for LLC DC-DC converter, totem-pole PFC and all-in-one power supply.
