Industry's fastest trr performance 600V super junction MOSFET PrestoMOS adds lower Ron, lower Qg "R60xxMNx series"

DFN1006 TP-RCLAMP3321P ESD Diode Low Capacitance

The world-renowned semiconductor manufacturer ROHM 's high-speed trr*1 600V super-junction MOSFET PrestoMOS ※ product group has added " R60xxMNx series", which is very suitable for motor drives such as white goods and industrial equipment that require low power consumption. PrestoMOS is the industry's fastest trr performance power MOSFET, known for its industry's smallest switching losses. It is highly praised for lowering the power consumption of white goods equipped with inverters.

The " R60xxMNx Series" developed this time has successfully reduced the Ron*2 and Qg*3 significantly by optimizing the ROHM's unique chip structure while maintaining the "high-speed trr performance" of PrestoMOS. Therefore, in a motor-driven application such as an inverter air conditioner, the power loss at a light load is reduced by about 56% compared with the conventional IGBT, and the energy saving effect is remarkable.

Not only that, the " R60xxMNx series" takes advantage of the simulation technology accumulated by ROHM for many years, and also achieves superior short-circuit withstand capability, which reduces the risk of damage caused by abnormal heat caused by circuit malfunction and helps to improve the application. reliability.

This series of products has been put into mass production with a monthly capacity of 100,000 units in December 2016. The production base of the previous process is ROHMApolloCo., Ltd. (Fukuoka Prefecture, Japan), and the production base of the later process is ROHMSemiconductor (Korea) Co. , Ltd. (Korea).

In the future, ROHM will continue to develop high-performance, high-reliability products that combine the advantages of ROHM simulation design technology, and continue to contribute to the further energy saving of society.

In recent years, the trend of energy conservation has been accelerating. With the revision of the Japan Energy Conservation Law, home appliances tend to adopt the APF (Annual Performance Fundion)*4, which is closer to the actual use situation, and no longer only pay attention to the startup of equipment with large power load and Energy saving under rated conditions requires a more energy-saving trend in normal operation with a small load. Nearly 50% of the world's electricity demand is said to be used to drive electric motors. With the popularity of air conditioners in emerging countries, the global power situation is getting worse every year. Under this background, ROHM has developed PrestoMOS, which is very suitable for motor drives such as white goods and industrial equipment such as air conditioners that require low power consumption, which can greatly reduce the power consumption during normal operation of the application and meet the energy saving needs of the society.

1. The industry's fastest trr performance, low Ron, low Qg, help to save energy

Generally, MOSFETs have the advantages of high-speed switching and low conduction loss in a low current range, which can effectively reduce power consumption when the device is in normal operation. The R60xxMNx Series leverages ROHM's unique Lifetime control technology to maintain the industry's fastest trr performance and lower Ron and Qg, making it ideal for energy-saving inverter circuits.

2. Superior short-circuit withstand capability to ensure reliability

Usually, once a short circuit occurs, there is a possibility that the circuit malfunctions, a large current exceeding a design value, an abnormal heat generation, or even a component damage. It has always been difficult to ensure superior short-circuit withstand due to the constraints between performance and short-circuit, and the "R60xxMNx series" takes advantage of ROHM's analog technology, the cause of thermal runaway---parasitic bipolar transistor Successfully optimized to ensure the short-circuit withstand capability necessary for motor drive helps improve application reliability.

3. Self-conducting loss is small

Self-conducting means that when the MOSFET is turned off, once the high-side main switch is turned on, the voltage between the drain and the source of the low-side MOSFET increases sharply, the voltage is sensed by the gate, the gate voltage rises, and the MOSFET malfunctions. This phenomenon causes the internal power loss of the MOSFET. The "R60xxMNx Series" can control this loss to a very small minimum range by optimizing the parasitic capacitance.

At the same time, a part of the TO-263 (LPTS) package was also prepared.

*1 trr: reverse recovery time

The time it takes for the switching diode to go from the on state to the fully off state.

*2 Ron: On-resistance (Ω)

The resistance value when the switching diode is turned on.

*3 Qg: Gate input charge amount

The amount of charge required to inject the gate electrode when the MOSFET is switched on/off.

*4 APF (AnnualPerformanceFactor)

The energy efficiency ratio when using household air conditioners throughout the year. The larger the value, the better the energy saving performance.
