650V GaN FET with 41mOhms On-Resistance in a TO-247

March 23, 2016 by Power Pulse1595211359

Transphorm Inc. introduced the TPH3207WS GaN field effect transistor (FET) with the lowest on-resistance (41 mΩ) 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 was announced during the Applied Power Electronics Conference (APEC 2016) and 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 mΩ) 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-GaNâ„¢) can be easily driven with off-the-shelf drivers and 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. And double the power density. Faster switching speeds from low capacitances and gate charge enable designers to reduce overall system costs. TPH3207WS samples are available to purchase now and priced at US$22.69 for 1,000-unit quantities.
