Toshiba offers a wide variety of MOSFETs that help reduce product size and power consumption, such as MOSFETs in ultra-small, thin packages and those with ultra-low ON-resistance that can be driven at a low voltage.
Toshiba has decades of experience in the development and manufacturing of discrete MOSFETs. Its main products include the mid- to high-voltage DTMOS IV Series with a VDSS of 600 V or so and the low-voltage U-MOS VIII-H Series with a VDSS of 30 to 250 V. This article presents an interview with the engineers who were in charge of the development of these MOSFETs.
U-MOS VIII-H is a high-efficiency MOSFET series specifically designed for use in the secondary side of AC-DC power supplies for notebook PC adapters, game consoles, servers, desktop PCs, flat-panel displays, etc., as well as DC-DC power supplies for communication equipment, servers and data centers. Fabricated with the latest Gen-8 trench MOS process, U-MOS VIII-H will help improve the efficiency of power supplies.
Toshiba has developed the Gen-4 super-junction 600-V DTMOS IV MOSFET series. Fabricated using the state-of-the-art single epitaxial process, DTMOS IV provides a 30% reduction in Ron•A, a figure of merit (FOM) for MOSFETs, compared to its predecessor, DTMOS III A reduction in Ron•A makes it possible to house lower Ron chips in the same packages. This helps to improve the efficiency and reduce the size of power supplies.
Toshiba offers MOSFETs in a wide range of packages ideal for various applications.
