Fully Qualified Low-R(on) 650 V GaN FET comes in TO-247 package.

Press Release Summary:

Available in TO-247 package that facilitates design and development, TPH3207WS GaN (gallium nitride) field effect transistor (FET) lets designers reduce overall power supply losses by as much as 40% while achieving up to 99% efficiency by implementing CCM bridgeless totem-pole PFC designs. On-resistance of 41 mΩ and Qrr of 175 nC help engineers improve system reliability, performance, and power density, and cascode configuration (EZ-GaN™) can be driven with off-the-shelf drivers.

Original Press Release:

Transphorm Introduces the Industry's Only Fully-Qualified 650V GaN FET with the Lowest R(on) in a TO-247

Lowest R(on) of 41mOhm and ultra-low Qrr of 175nC increases power density and achieves higher efficiencies over a broad range of power levels

GOLETA, Calif. – Transphorm Inc., a leader in the design and manufacturing of JEDEC-qualified 650V GaN (gallium nitride) semiconductors, introduces the TPH3207WS GaN field effect transistor (FET)  with the lowest on-resistance (41 mOhm) in a TO-247 package that reduces system volume as much as 50% without sacrificing efficiency. The device's low Rds(on) and ultra-low Qrr (175nC) bring the benefits of GaN to applications that previously relied on silicon, enabling engineers to achieve power-dense solutions with reduced component count and improved reliability in high-voltage power conversion applications.

The TPH3207 improves system reliability, performance and power density in an easy-to-handle cascode configuration.  These advantages are being realized in hard-switched bridges and the continuous conduction mode (CCM) bridgeless totem-pole power factor correction (PFC) designs being used in on-board chargers, solar inverters, telecom power supplies and other power conversion applications. Transphorm's GaN FET portfolio is also strengthened with the introduction of the TPH3208 family (130 mOhm) in industry-standard TO-220 and PQFN packages, further enabling the GaN revolution.

Key features and benefits of the TPH3207:

--  Fully-qualified GaN technology. Extensive qualification and long-term reliability of all Transphorm devices, including extended tests for early infant mortality failure and long-term wear out failures, is unmatched by any GaN manufacturer.

--  Ease-of-use. Cascode configuration (EZ-GaN™) can be easily driven with off-the-shelf drivers and its TO-247 industry-standard packaging allows for ease of design and development and low EMI.

--  Enables more efficient topologies. Allows designers to reduce overall power supply losses by as much as 40% while achieving up to 99% efficiency by implementing CCM bridgeless totem-pole PFC designs.

--  Double the power density. Faster switching speeds from low capacitances and gate charge enable designers to reduce overall system costs.
