Reliability Acquired
by Supplying
Automotive Devices Over Half a Century

Sanken has long been engaged in the automotive industry since 1962, beginning with the manufacturing of alternator diodes.

Alternators are used to generate electricity in the engine, therefore requires reliable devices that can withstand the most stringent environment. Later on, we have expanded our portfolio with other discrete products and ICs, which are now used in automobiles worldwide.


xEV System

Sanken offers various devices suitable for xEV systems with high voltage batteries.


Our Approach

The acceleration of technology development caused by both internal and external factors, such as the progress of autonomous driving and the increasingly strict measures against environmental issues, has led to what is said to be a once-in-a-century change.

As a result, there are increased demand for the following:

- Improved fuel efficiency by efficient use of electricity
- Optimization of control technology for motors and electronic loads

In addition, semiconductor devices with higher reliability are being required in order to improve safety.

Today, customers seek high efficiency vehicles to realize a more compact, lightweight, and high reliability devices. Sanken Electric offers a portfolio of semiconductors including MOSFETs, IGBTs, as well as diodes and other high-efficiency power devices, highly reliable monolithic ICs that are available in many packages to meet these needs. Also, board assembly is carried out at our own factory, and production of modules are also available.

MCU and Control ICs

We develop a diverse selection of MCUs that are capable of monitoring power supplies to support complex and sophisticated systems, as well as efficiently managing power devices.

MCU and Control ICs


Our LEDs will achieve your intended product appearance with their unique packages and provide any desired color through a combination of LED chips and phosphors. Sanken Electric’s color management technology helps your application turn into beautiful in-vehicle lighting.


Distinctive Packaging Technology

Our own packages boast an extensive selection — thin, small, thermally enhanced, or more — so that chips to be mounted can fit into conditions your product must satisfy.

Our Proprietary Packaging Technology



SAM2 Series

SAM2 Series Special Page

The SAM2 series are 3-phase brushless motor drivers in which output transistors, pre-drive circuits, bootstrap diodes with current-limiting resistors, and a temperature-sensing thermistor are highly integrated. The product lineup offers devices having output transistors with breakdown voltages of up to 650 V and rated currents of 30 A/50 A.
The ICs are suitable for 3-phase motor drivers used in on-board high-voltage auxiliary systems.
