The package covers 62 models including SOD123FL and TO220AC, and is sold globally through channels such as DigiKey and Mouser.
Nexperia (Anshi Semiconductor)
Dutch brand, focusing on high voltage and high-frequency scenarios. Recently, a 650V ultra fast recovery rectifier diode was launched, which adopts D2PAK dual pin package (SOT8018), optimizes the creepage distance, meets the IEC 60664 standard, and is suitable for high-density designs such as photovoltaic inverters and server power supplies. Certified according to IATF 16949 and other standards, suitable for automotive high-voltage scenarios.
Vishay、ON Semiconductor、Infineon
International top tier manufacturers, with product lines covering general rectifiers to fast recovery diodes (FRED), silicon carbide (SiC) devices, etc., dominate the industrial power supply and consumer electronics fields. According to the 2024 market report, these companies, together with Renesas, Dior Inc., and others, hold over 60% of the global market share.
2、 Major domestic brands
HVC (Hewes)
Positioned as a high-end alternative, specializing in the high-voltage medical/industrial equipment market. Its high-voltage diode series (such as HVDSL series) fully replaces the American HVCA models (such as UXFOB), with parameters covering 2-40kV reverse voltage, 20-300mA current, recovery time of 75-100ns, and price only one-third of imports. Applied to the double voltage circuit of X-ray machines and CT equipment, with technology benchmarking against American and Japanese products.
HVDIODE Electronics
An enterprise in Anshan, Liaoning, with a strong focus on high-power customized high-voltage components. The product has a back pressure of 2-50kV and a current of 1-100A. It adopts a patented layered heat dissipation structure and has a node temperature resistance of 175 ° C. It is suitable for harsh environments such as military, high-speed rail, microwave ovens, etc. and supports OEM design.
Dachang Electronics
Established in 1994, a well-established manufacturer in Rugao, Jiangsu, with an annual production capacity of over 1.5 billion units. Our main products are axial rectifiers and TO220 packaged fast recovery diodes, supplied to home appliance companies such as LG and Hisense, with a focus on high cost-effective universal models.
Jinan Gang Positron&Crystal Constant Electron
Gang Positron: 80% of our products are exported to Europe and America, covering Schottky TVS、 Bridge pile (1-50A), proficient in the field of small and medium power consumer electronics;
Jingheng Electronics (founded in 1958): Brand "JF Jifu", China's first Schottky diode producer. Bridge piles (such as MB10S) have obtained ROHS certification and provide OEM services for GE, Philips, and others.
3、 Market Pattern and Segmented Fields
Product types: Fast recovery diodes (automotive/photovoltaic), high-voltage rectifiers (medical/industrial), and general-purpose rectifiers (home appliances) are the three main tracks;
Regional distribution:
East China (Qiangmao, Jingheng) leads in vehicle regulations and exports;
Huabei (Shuli) focuses on high-pressure customization;
South China (HVC agent) covers medical equipment replacement;
Localization trend: gradually replacing imports in high-end fields such as high voltage (10kV) and automotive AECQ101, but IC integrated power devices still rely on international giants.
Table: Mainstream brand positioning and advantageous areas
|Brand type | Representative enterprise | Core technology/product | Typical application areas|
|International Head | Pan Jit | 200V Automotive Grade Fast Recovery Diode (20ns) | Automotive Electronics (ESP, Water Pump)|
|| Nexperia | 650V Ultra Fast Recovery Tube (D2PAK Package) | Photovoltaic Inverter, Server Power Supply|
|Domestic leading | HVC | High voltage alternative HVCA (40kV/30mA) | Medical CT machine, X-ray equipment|
|| Shuli Electronics | High power customization (50kV/100A) | Military, high-speed rail, industrial microwave|
|Cost effectiveness/universality | Dachang Electronics | Axial rectifier tube, TO220 package | Home appliances, display power supply|
Current selection suggestion:
Automotive Electronics: Priority given to the QiangMao automotive grade series (AECQ101 certification);
Medical/Industrial High Voltage: Evaluate HVC or Shuli Electronics, with parameters comparable to imports and significant cost advantages;
Consumer electronics: Dachang and Gangzheng's universal models have outstanding cost-effectiveness and short delivery cycles (Gangzheng supports 24-hour small batch shipping).
Geopolitics is driving the deepening of domestic substitution, especially in high-pressure and high reliability scenarios. Local enterprise technology has approached international levels, and supply chain response speed has become a key competitive advantage.
