Contest brief

Infineon’s technology and production advancements turn power semiconductors into cheaper, yet high-performance solutions. This opens up a vast range of new potential applications for power MOSFETs with silicon improving the behavior of systems.

Designs that use outdated electromechanical switches and relays do not maximize power consumption, are bulky and inefficient. Replacing these with electronic switches improves thermal performance and power density, resulting in a smaller footprint and reduced cost.

We are challenging the community to generate new applications where Infineon's 600 V CoolMOS™ C7 Gold superjunction MOSFETs would have a significant impact on replacing relays and diodes through static switches in new, not yet considered application fields. What innovative designs can you come up with to replace conventional mechanical relays / diodes with low-ohmic high voltage switches?


We are giving away thousands of dollars in prizes to the most creative use of the 600 V CoolMOS™ C7 Gold superjunction MOSFET in automotive, consumer and industrial applications.

Free Hardware Giveaways

Are you an expert when it comes to working with MOSFETs but need the hardware to get started? We are giving a strip of five 600 V CoolMOS™ C7 Gold superjunction MOSFETs to the first 100 people to submit their ideas.

Need to purchase the MOSFET to start your project? Buy here.


Submissions will be judged by the Infineon Team. Read through judging criteria on the Rules tab. Your judges are:

  • Stefan Gamerith - Senior Product Marketing Manager
  • Giovanbattista Mattiussi - Product Marketing Manager
  • Franz Stueckler - Application Engineer

Infineon’s 600 V CoolMOS™ C7 Gold in TOLL package

Infineon's 600 V CoolMOS™ C7 Gold superjunction MOSFET brings together the benefits of low RDS(on) *A and improved thermal properties of the TO-leadless package to enable an SMD solution for high current applications.

The most notable benefits are improved power density due to low RDS(on) in small footprint and production cost reduction through quick assembly times by SMD. All the applications that required lots of paralleling MOSFETs in the past will gain from the low RDS(on) by much lower device count ( = reduction of BOM).



The Infineon team and other participants are accessible for help and questions on the contest discussion forum. For access, sign up for a Spectrum account and join the infineon-challenge channel. An Infineon expert will be online to answer questions live during the following times (except during the holiday season: 12/22/18-1/6/19):

  • Mondays 12 PM -2 PM CEST (3-5 AM PST)
  • Fridays 10 AM - 12 PM CEST (1-3 AM PST)

Technical Resources

Infineon's technical webinar with Giovanbattista Mattiussi on October 25th at 8:00am PDT/5:00pm CEST discussed industrial and consumer applications where superjunction MOSFETs replicate or integrate the function of electromechanical relays and circuit breakers. It also covered how Infineon leverages its superjunction technology in these applications and discover what opportunities this new approach can bring.

Sample Applications

Need some inspiration to get started? Here are some sample applications of how you could use the 600 V CoolMOS™ C7 Gold superjunction MOSFET:

Example 1: DC Home

All electronic controlled loads work with a DC generated by PFC out of an AC. Why not directly use a DC connector via 600 V CoolMOS™ C7 Gold superjunction MOSFET instead and save all conversion losses?

Example 2: Battery Storage Protection in Solar Plants

If DC distribution is applied to residential buildings, solar plants may become the energy source of choice with battery packs installed for energy storage. Use 600 V CoolMOS™ C7 Gold superjunction MOSFET to create a solid DC circuit breaker battery protection to increase life time, lower response time, shrink volumes and gain energy efficiency!

Example 3: Battery Main Switch

In electric vehicles (EV), once the energy storage is full, it is convenient and ecological to use the energy to charge the EV. One fundamental part of an EV is the switch which protects the battery packs. Prompt intervention is vital to avoid major consequences like fire or explosions. Design a solid battery switch based on 600 V CoolMOS™ C7 Gold superjunction MOSFET for quicker intervention time, less maintenance, less footprint and more safety.
