Toshiba Electronic Devices & Storage Corporation has launched six products featuring the DTMOSⅥ 600V series N-channel power MOSFET chips, mounted in a four-pin TO-247-4L(X) package to reduce switching loss. These devices are suitable for servers in data centers, switched-mode power supplies for industrial equipment, and power conditioners for photovoltaic generators.
By optimizing the gate design and process, the DTMOSⅥ 600V series, which includes the new products, has reduced the value of drain-source On-resistance×gate-drain charge―the figure of merit for MOSFET performance―by approximately 52% compared to Toshiba’s existing DTMOSⅣ-H series products with the same drain-source voltage ratings.
The new products feature the four-pin TO-247-4L(X) package with a signal source terminal for gate drive. Compared to the three-pin TO-247 package, the TO-247-4L(X) package allows for Kelvin connection of the signal source terminal for gate drive, reducing the influence of the inductance of the source wire inside the package. This enhances high-speed switching performance and helps improve the high efficiency of uninterruptible power supplies (UPS), photovoltaic inverters, and more.
Toshiba also offers tools that support circuit design. Alongside the G0 SPICE model, which verifies circuit function in a short time, highly accurate G2 SPICE models that accurately reproduce transient characteristics are now available.
Toshiba will continue to expand the DTMOSⅥ 600V series lineup to enhance the efficiency of switched-mode power supplies for industrial equipment, aiming to achieve carbon neutrality.
