Transphorm, a leader in the design and manufacturing of JEDEC-qualified 650V GaN (gallium nitride) semiconductors, introduced 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:
- 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.
