    650V GaN FET with the lowest R(on) in a TO-247

    May 31, 2016
    Transphorm has introduced the TPH3207WS GaN field effect transistor (FET) with the lowest on-resistance (41 mW) in a TO-247 package that reduces system volume as much as 50% without sacrificing efficiency.

    Transphorm has introduced the TPH3207WS GaN field effect transistor (FET) with the lowest on-resistance (41 mW) 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 mW) 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.
    • Package, availability and pricing: TPH3207WS samples are available to purchase now and priced at US$22.69 for 1,000-unit quantities.
