Zhuzhou CRRC Times Semiconductor

What Zhuzhou CRRC Times Semiconductor does

Zhuzhou CRRC Times Semiconductor Co., Ltd. is a China-based IDM (Integrated Design and Manufacturing) power semiconductor company and a wholly-owned subsidiary of Zhuzhou CRRC Times Electric Co., Ltd. (SSE STAR Market: 688187), itself majority-owned by the state-owned CRRC Group under SASAC. The company designs, fabricates, packages, and tests high-power semiconductor devices across four product lines: IGBT and FRD modules, silicon carbide (SiC) MOSFETs and modules, bipolar devices (rectifier diodes, thyristors, IGCTs), and supporting application simulation and technical services. It operates China's first domestically manufactured 8-inch IGBT chip production line, holds a top-three global position in full-series high-voltage thyristors, and has continuously invested in power semiconductor R&D since 1964, augmented by the 2008 acquisition of UK-based Dynex Semiconductor.

The company sells primarily through direct B2B enterprise channels to OEM customers in rail transit, new energy vehicles, ultra-high-voltage power transmission, and clean energy/industrial applications. Pricing is quote-based on custom module specifications with long qualification cycles. Geographic footprint spans four Chinese production bases (Zhuzhou headquarters, Yixing, Hefei, Guangzhou) plus the UK Dynex subsidiary, serving customers across Asia and Europe including CRRC Group, State Grid, GAC Group (via the Guangzhou Qinglan joint venture), and export programs such as the Indonesia Jakarta–Bandung high-speed rail.

Revenue mechanics rest on hardware sales of power semiconductor components and modules, with vertical integration from wafer fabrication through module assembly providing cost and supply control. Recent expansion is heavy: the CNY 5.9 billion Yixing project (360,000 eight-inch substrates, 5 million IGBT modules annually), the 2024 establishment of Hefei CRRC Times Semiconductor for new energy and rail applications, the Guangzhou Qinglan joint venture with GAC Components targeting 3 million NEV modules per year, and a March 2024 ~USD 685.8M state-backed funding round illustrate an aggressive scale-up into automotive and renewable energy silicon and SiC power electronics beyond the legacy rail transit core.
