Last Time Buy for CISSOID High temperature Components

For the past 8 years, CISSOID SA has been transitioning to a new business, focused on developing SiC based solutions to support the transition from the conventional internal combustion engine to electrification for both off-road vehicles and conventional EV’s. CISSOID now provides solutions including software, hardware and complete inverter reference designs.

CISSOID had indicated to its Hi-Rel / High Temperature customers that we would continue to support this business for as long as possible. Unfortunately, our ability to provide ongoing support has been removed by our supplier.

Our wafer fab foundry X-FAB recently notified us that they will discontinue the XI10 process by March 2025. This process has been running for many years and is now getting replaced by more recent technologies. As you may know, most of the CISSOID High Temperature products, rated up to 175°C or 225°C, are using X-FAB’s XI10 process. This decision is creating a major disruption of our supply chain as there is no equivalent on the market to the XI10 process.

In this situation, CISSOID has no choice but to announce the discontinuation of the components made with this technology. CISSOID is announcing a Last Time Buy (LTB) order for those components. This situation concerns the following products (see exhaustive list further down this page):

• Complete CHT family (product with ordering reference starting with CHT)
• CMT family excluding SiC power modules and SiC gate driver boards
• CXT family excluding SiC power modules

Orders with standard terms and conditions for all discontinued components can be placed until 30th December 2024,
with delivery dates scheduled before 30th June 2025.

Last Time Buy orders can already be placed, until 28th February. Terms and conditions for the LTB orders will be communicated very shortly but please do not wait. Passed this date, we will not be able to take further orders on all affected references.

We understand this unfortunate situation will create many challenges on your side and we are committed to supporting you to secure your production for the coming years, however, we do urge you to take urgent action to contact all customers that you have sold CISSOID products to over the past 10 years and to discuss and consolidate their total End-of-Life requirements by device and communicate these requirements to CISSOID as soon as possible. If you miss the 28th February 2025 order date, there will be nothing we can do to support your customers' requirements. Please contact us if you have any questions or if you wish to organise a specific meeting on this topic.

We are looking forward to hearing from you and to discussing further your need, so we can better support you.

For further information, support or to discuss orders placed with APC Technology Group, please contact a member of our team.
