Announcing four new models of our 4th generation power MOSFET with 24% reduced figures of merit, which contribute to reduced size and power consumption in a variety of mobile applications

Aug. 18, 2020

Shindengen Electric Manufacturing Co., Ltd. has started mass production of four new models for its EETMOS4 Series lineup of Power MOSFET. This series uses a new structure chip and Cu clip to realize low loss and large current capacity in a 5×6 mm size compact package, greatly contributing to reduced size and lower power consumption for longer operation times in various motor drive circuits, power supply circuits, relay related and other applications in battery driven devices . In addition, the series also utilizes gull-wing shaped package terminals to achieve high reliability mounting.


In recent years there has been a rapid increase in the number of stick-type vacuum cleaners, power tools, motorized bicycles, and other battery-equipped products.
Other new markets, such as drones, also continue to expand. There is demand for more compact sizes, and longer operating times through lower power consumption for these battery driven devices, leading to even greater demand for reduction in size and higher efficiency in the power semiconductors which are key parts of these devices.
Shindengen has announced a new range of Power MOSFET, 40V-120V in compact package, following the market trends and needs.
These products reduce FOM (Figure of Merit), which is the product of on resistance and total gate load, by 24%*1, and in addition to increasing power supply circuit conversion efficiency, also decrease mounting area by 54%*1, to contribute to reduction in size and improved efficiency of automation systems by mounting our new structure, 4th generation power MOSFET (EETMOS4) on compact packages using Cu clip connections which have low electrical resistance and high heat dissipation.
In addition, because mobile devices which use batteries as their power source require strong soldering which is resistant to impacts, the new EETMOS series offers strong solderability and robust solder fillet by means of its plating and gull-wing leads structure to fulfill the exact requirement of automotive quality level.
