DTMOSⅥ 600V N-Channel Power MOSFET in TO-247-4L(X) Package Helps Improve Efficiency of Switched-Mode Power Supplies for Industrial Equipment
Toshiba Electronic Devices & Storage Corporation ("Toshiba") 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.
特点
- Low RDS(ON)×Qgd (drain-source On-resistance×gate-drain charge) and high efficiency of switched-mode power supplies
- Four-pin TO-247-4L(X) package adopted: Reduces switching loss by adding a signal source terminal for gate drive
Features Explanation
1. Low RDS(ON)×Qgd (drain-source On-resistance×gate-drain charge) and high efficiency of switched-mode power supplies
By optimizing the gate design and process, the DTMOSⅥ 600V series products have reduced the value of drain-source On-resistance per unit area by approximately 13%, gate-drain charge by approximately 45%, and 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 rating. This means the DTMOSⅥ series has a better trade-off between conduction loss and switching loss, which helps improve the efficiency of switched-mode power supplies.

2. Four-pin TO-247-4L(X)[2] package adopted: Reduces switching loss by adding a signal source terminal for gate drive
In the case of a three-pin type package, as shown in Figure 2., when the gate drive voltage VDRV is applied, the inductance component LS of the source wire and the gradient dID/dt component of the drain current ID generate a counter electromotive voltage VLS. Therefore, the gate drive voltage VDRV is reduced by the generated counter electromotive voltage VLS. Thus, the voltage VGS applied between the gate and source of the FET chip is the gate drive voltage VDRV reduced by the counter electromotive voltage VLS. This slows down the switching speed of the MOSFET.
On the other hand, in the case of a four-pin type package, as shown in Figure 3., the effect of counter electromotive voltage VLS is reduced by connecting the signal source terminal for gate drive close to the FET chip. As a result, in the four-pin type package, the voltage VGS applied between the gate and source and the gate drive voltage VDRV are approximately the same value, improving the switching speed of the MOSFET compared to the three-pin type package.
Note:
[2] The appearance and dimensions of the TO-247-4L(X) package differ from Toshiba’s existing four-pin package, the TO-247-4L. Please note that there is a dimensional difference of more than 10% in the arrowed parts of the diagram below. For details, please refer to the links for each package.
