Q.16 Are samples also available for other customers?
A.16 We are working with a select group of customers based on the demands placed on applications engineering
teams. As the product portfolio develops, including the controller and driver ICs, additional demo boards and
support collateral will also become available. All documentation will be released in combination with dedicated
product launches.
Q.17 When will it go into high volume production?
A.17: Infineon is in volume production on 100 V technology devices in Class-D Audio amplifiers used in consumer
products. We are not in a position to commit on other 100 V or 600 V products.
Q.18 Where are products developed and where are they produced?
A. 18 We kindly ask for your understanding that this information is not shared at this point in time.
Q. 19 What exactly is the status of development right now?
A.19 We kindly ask for your understanding that this information is not shared at this point in time.
Q.20 Can I have application notes, samples, ongoing prepared material, Demo-boards?
A20.We are working strategically with a select group of customers based on the demands placed on applications
engineering teams. As the product portfolio develops, including the controller and driver ICs, additional demo boards
and support collateral will also be available. All documentation will be released in combination with dedicated
product launches.
Q.21 Why should customers wait for the IFX Solution?
A.21 Combining Infineon and IR’s GaN teams has led to a level of GaN expertise that is unmatched. We are working
hard and will bring GaN products into the market as soon as our quality and reliability requirements are met. In
addition, once we launch our products we will have enough capacity to sustain high volume ramp-up and can even
offer a second source for part of our portfolio.
Miniaturization and energy savings will be enabled by GaN devices and solutions. Being in the leading position on
this path is a common goal for Infineon and its customers
Q.22 Which key customers have already sampled with GaN Devices?
A. 22 We kindly ask for your understanding that this information is not shared at this point in time.
Q.23. What is the initial feedback?
A.23 100 V GaN product is released in volumes for Class-D Audio amplifiers with a worldwide leader in Audio
systems that has an excellent track record. All other samples of cascode and enhancement mode HEMTs are in
evaluation with some of Infineon´s key customers who are building their experience around GaN in PFC Totem Pole
FB and main DCDC boards targeting the highest efficiency. SMD packages are much appreciated as customers also
perceive thru-hole is a no-go for high frequency designs. They are seeking a thermally optimized SMD package for
high power applications (currently covered by TO220/TO247 standard packages).
Q24. What current ratings are offered? What voltage ratings?
A.24 100 V and 600 V class, although not fully released as of today. No information yet released regarding R
DS(ON)
/current ratings.
Q.25a How does GaN compare to SiC?
A.25a: We see the sweet spot for active SiC devices in the high-voltage / high power domain that is above 600 V. At
this point in time Infineon believes that in these higher voltage areas (e.g. at 1200 V) SiC FETs are more competitive
than GaN and much more mature. Additionally, they feature full avalanche ruggedness and high short circuit
robustness due to excellent thermal conductivity of SiC.
