Jiangsu GuanLong Integrated Technology Unveils Full-Spec Single-Phase Thyristor Chip Series for Industrial Power Control Applications

2026-09-20

ZHANGJIAGANG, CHINA – September 20, 2026 – Jiangsu GuanLong Integrated Technology Co., Ltd., a leading professional manufacturer of high-performance power semiconductor components headquartered in Zhangjiagang Free Trade Zone, Jiangsu Province, China, has officially launched its comprehensive upgraded single-phase thyristor chip product series. Featuring full-size coverage, complete voltage grade options, and customizable electrical parameters, the new industrial-grade thyristor chips deliver superior stability and durability, catering to diverse high-precision power control needs for global industrial and commercial applications.

Single-phase thyristor chips serve as indispensable core semiconductor components for industrial power regulation, AC/DC rectification, and fast switching control. Widely utilized in industrial power supplies, motor speed control, electric heating systems, intelligent lighting dimming, and full-set industrial automation equipment, these power chips require excellent surge resistance and wide-temperature adaptability for long-term stable operation. To solve the pain points of unstable performance and narrow application range of traditional thyristor chips, GuanLong Integrated Technology has upgraded core production processes and electrical parameters, launching two mature single-phase thyristor chip product clusters to cover low-power, medium-power, and high-power industrial scenarios.

Comprehensive Product Specifications Cover Low to High Power Scenarios

The newly released single-phase thyristor chip series boasts an ultra-wide dimensional coverage range from 2.4*2.4mm to 21.6*21.6mm, with matched forward current specifications spanning 8A to 200A, realizing full-gradient power matching. The product lineup includes mainstream 800V and 1100V repetitive peak voltage models, plus a customized 1600V high-voltage resistant version for special high-insulation industrial environments. This complete specification matrix enables GuanLong’s thyristor chips to perfectly adapt to all mainstream power control equipment in the industrial market.

Every single-phase thyristor chip from GuanLong Technology maintains highly consistent and reliable electrical performance. The gate trigger current is strictly controlled between 20mA and 70mA, with a maximum gate trigger voltage of 1.50V, ensuring ultra-sensitive and stable gate triggering response during equipment operation. The series features an ultra-low on-state peak voltage drop: standard models achieve ≤1.45V, while optimized high-power models reach ≤1.30V. The optimized voltage drop design effectively reduces operating power consumption and heat generation, significantly improving the energy efficiency and service life of terminal power equipment.

Engineered for harsh industrial working conditions, GuanLong’s single-phase thyristor chips exhibit exceptional extreme environmental resistance and anti-surge capability. The maximum on-state surge current can reach up to 4000A (tested under 10ms standard pulse), which effectively resists instantaneous current impact during equipment startup and operation. All products pass strict dv/dt (off-state voltage critical rise rate) and di/dt (on-state current critical rise rate) industrial standard tests at 125℃. The full series supports a wide operating temperature range of -40℃ to 125℃, enabling stable continuous operation in high-temperature, low-temperature, and large temperature difference industrial scenarios.

Optimized Structural Design & Patented Technical Advantages

This upgraded single-phase thyristor chip series adopts high-precision premium metal packaging technology. Both anode and cathode surfaces use high-conductivity silver metal, and the cathode metal supports optional aluminum material customization, balancing excellent electrical conductivity and cost competitiveness. For high-power models with a size of 6.8*6.8mm and above, dual-color green and red protective glue is applied on the surface, which greatly enhances the chip’s insulation performance, anti-aging ability, and corrosion resistance. The optimized structural design ensures long-term stable operation of thyristor chips in continuous high-load industrial equipment.

As a core independent R&D product of the company, the full-range single-phase thyristor chip series is protected by the national invention patent CN1783516A, representing a leading technological breakthrough in domestic power semiconductor chip manufacturing. Different from conventional fixed-spec thyristor chips, all products in this series support full personalized customization. Professional technical teams can adjust core electrical parameters, chip size, and structural configurations according to customers’ terminal equipment design standards and actual application scenarios, providing one-stop customized power semiconductor chip solutions.

Strict Industrial Testing Standards Ensure Stable Mass Production Quality

To guarantee stable and consistent mass production quality, all single-phase thyristor chips undergo rigorous industrial authoritative testing. The on-state surge current (ITSM) is verified under standard 10ms working conditions; dv/dt parameters are tested at 125℃ environment with 2/3 VDRM reference standard; di/dt performance is calibrated at 125℃ under 2X rated current; and the on-state peak voltage drop is detected under 3X rated current working conditions. Strict high-temperature resistance and high-load endurance testing eliminate performance differences of bulk products, making GuanLong’s thyristor chips fully compliant with the quality standards of mid-to-high-end industrial power equipment.
