Discrete: a single-function semiconductor device such as a transistor or diode
IGBT: Insulated Gate Bipolar Transistor
1．Background
Power semiconductors, which are mounted on industrial equipment such as inverters, uninterruptible power systems and power conditioners, electric and hybrid vehicles, and communications devices, are a key device in the realization of energy conservation and a stable power supply.
The size of the market for the industrial and communications equipment where discrete IGBTs are used is estimated to reach approximately 50 billion yen in 2016 and subsequently grow at an annual rate of 5% (source: IMS).
As the demand for energy has been expanding globally in recent years, there is a growing need for the energy-saving performance of such industrial and communications equipment. There is also a strong demand for downsizing and space-saving of the equipment themselves.
We are now releasing high-speed discrete IGBT products that meet these market needs.
2．Product Features
（1） Contributes to energy conservation by reducing power loss
Power semiconductors repeatedly perform rapid switching (turning electricity on and off) to convert DC to AC or control voltage. The new product series has made the IGBT chip thinner for miniaturization, thereby reducing power loss (turnoff loss) in switching operation by approximately 40% compared to conventional products (High-Speed V Series). This contributes to energy saving and power cost reduction of the devices on which to mount the products.
（2） Realizes downsizing of devices
Loss in switching operation has been reduced (heat generation suppressed) to realize compatibility with higher switching frequencies* (20 to 100 kHz) compared to conventional products (around 20 kHz).
This makes it possible to downsize the peripheral parts (coils and transformers) of the devices on which to mount the products, and contributes to the downsizing of the equipment itself and total cost reduction.
