Announcing the launch of high current, high withstand voltage bridge diodes with a 60% increase in rated current
-Contributes to higher power for air conditioners and other home electronics white goods-

Dec. 14, 2022

Shindengen Electric Manufacturing Co., Ltd. has begun sales of the D40XB100 bridge diodes for air conditioners and other home electronics white goods.

The D40XB100 is a bridge diode with a rated current of 40A and withstand voltage of 1000V.
Population growth and rapid economic development in developing countries are expected to triple the number of air conditioners installed worldwide by 2050. In response to this increased demand, air conditioners are required to have high heating and cooling capacity and a variety of additional functions, and are becoming higher powered. As such, there is also demand for bridge diodes to have higher current capacities.

To satisfy these needs, the D40XB100 has achieved a 60% increase over existing products in rated current to 40A through revision of the internal structure of the 1000V bridge diodes which have been available up until now. The new product uses a 5S GEN2 structure in the same external package as the 5S, which has been used in numerous applications in the market and has earned a reputation for high quality, to improve package heat dissipation and reduced terminal temperature. These features can contribute to higher power for air conditioners and other home electronics white goods.

Sales of this product are expected to begin in February 2023.

■ Features

  • Rated current of 40A and withstand voltage of 1000V
    Contributes to higher power for devices by increasing rated current 60% over existing products
  • The adoption of 5S GEN2 packages【Fig.1】
    Package features an internal structure with superior heat dissipation and less temperature differences between terminals
  • Other features
    Insulated SIP single-phase bridge diodes
    UL1557 certified product

Shindengen's 5S package has an internal structure with excellent heat dissipation due to its thermal design, and the temperature difference between the four chips and terminals is extremely small. This package is ideal for bridge diodes with extremely high component reliability and mounting reliability.

■ Typical Applications

・Large air conditioner
・Commercial air conditioner
・Industrial equipment power supplies.
