2017/10/12 Littelfuse IXYS acquisition:new step towards IGBT consolidation

Expected to reach more than US$ 5 billion in 2022 (1) , the IGBT market is showing a well-established supply chain with strong partnerships and companies positioned at each level.
KnowMade and Yole Développement, both part of Yole Group of Companies take today a closer look on the industry structure and comment its evolution.

Littelfuse is developing circuit protection with growing global platforms in power control and sensing. IXYS is strongly involved in the development of power semiconductors, solid-state relays, high voltage integrated circuits, and microcontrollers.
Both companies have strong synergies: they have for example the same customers’ portfolio composed of the electronics, automotive and industrial companies. Under this merger, their aim is to propose a relevant combination of their technical expertise and create value for their common customers’ portfolio to become a key IGBT player. With this acquisition, Littelfuse gradually enlarges its role within the IGBT market and takes clearly part in the market consolidation.
This acquisition is also supporting Littelfuse’s activities in power module design. Low inductance and good thermal performance become today a “must-have” to sell power devices.
“Power packaging is now a key knowledge that must be optimized to obtain good performance at the module level”, details Dr. Pierric Gueguen, Business Unit Manager at Yole. “Power packaging management will clearly accelerate the adoption of innovative technologies including WBG . Thus it is not a surprise to see many leading power electronics companies to move towards this level of the power electronics supply chain (2). ” For example, in the SiC area, Cree (today Wolfspeed) adopted this strategy with the acquisition of APEI in 2015.
With both deals, Cree (with APEI) and Littelfuse (with IXYS) expanded their expertise towards the packaging technologies, especially for SiC.

Thus Littelfuse confirms its penetration within the SiC industry, initially initiated with its strong investments in Monolith Semiconductors in March 2017. Today’s SiC market is still dominated by discrete devices. However, that situation will soon change, explain Yole Développement’s analysts. Indeed hybrid modules are already penetrating some applications and full SiC modules are coming with dedicated packaging solutions (3) .
“With IXYS acquisition and investments within Monolith company, Littelfuse modifies its market positioning: the company adds another activity in its products portfolio: the development of SiC-based power electronics solutions”, comments Nicolas Baron, CEO & Founder, KnowMade. “Based on its impressive patent portfolio including more than 400 patents and patent applications related to the power semiconductor industry, IXYS is showing a strong knowledge of IGBT modules packaging.” Under this context, Littelfuse will also get soon the capability to propose SiC power modules.
Today a comprehensive analysis of IXYS and Littelfuse patent portfolios reveals the complementarity of their expertise and positioning focused on IGBT market segment as well as their strategy to offer dedicated SiC-based products in a near future.

Tomorrow will probably see more and more mergers and acquisition within the IGBT industry. IXYS acquisition by Littelfuse is not the first case and will not be not the last…
KnowMade and Yole are daily working together to mix their vision of the industry, understand the supply chain evolution, identify new deals and analyze business opportunities. Yole Group of Companies ‘reports and custom products are offering an in-depth overview of the power electronics industry, the competitive landscape, the technology roadmaps and more.
