Turn Off Thyristor: Global Market, Suppliers, and Technical Guide 2026
Introduction: What is a Turn Off Thyristor?
A turn off thyristor, also known as a Gate Turn-Off thyristor (GTO), is a power semiconductor device that can be turned on by a positive gate current and turned off by a negative gate current. Unlike conventional thyristors (SCRs) which require the main current to drop below a holding value to switch off, a GTO allows full control via the gate terminal. This makes it a key component in high-power applications such as motor drives, traction systems, industrial inverters, and power grids. The GTO thyristor bridges the gap between standard thyristors and more modern IGBTs, offering high voltage and current ratings with controlled switching.

中国メーカーを選ぶ際に考慮すべき要素
Quality Certifications
Verify that the manufacturer holds ISO 9001, IATF 16949 (for automotive), or UL certifications. Many Chinese factories now comply with international standards.
Production Capacity and Lead Time
Assess their monthly output of GTO units. Smaller factories may offer flexibility, while larger ones ensure consistent supply.
Technical Support and R&D
Look for manufacturers with in-house engineering teams capable of customizing GTO parameters like voltage, current, and switching speed.
Cost vs. Reliability
Chinese manufacturers often offer 20-40% lower prices than global counterparts. However, balance cost with long-term reliability and warranty terms.
Shipping and Logistics
Check if the manufacturer has experience with international shipping, especially for sensitive semiconductor components requiring anti-static packaging.

Introduction to Chinese Factories
Chinese GTO factories are concentrated in the Yangtze River Delta (Jiangsu, Zhejiang, Shanghai) and Pearl River Delta (Guangdong). These facilities range from state-owned enterprises like CRRC Times Electric, which supplies high-power GTOs for high-speed trains, to private innovators like Yangzhou Yangjie, known for cost-effective modules. Many factories have adopted automated assembly lines and cleanroom environments to meet global quality standards. A typical mid-sized factory in Wuxi produces 50,000 GTO units per month, with lead times of 6-8 weeks for standard models.
