Import Diode Module Mdc110a — Buy in Bulk from Supplier in China

The Diode Module MDC110A is a full-wave rectifier module designed for high-voltage power conversion, featuring an electrically isolated chip and baseboard rated for 2500V AC isolation. It is constructed using silicon diode chips mounted on a ceramic substrate, with a sealed epoxy package that meets IEC 60664-1 insulation requirements. The module is rated for continuous forward current of 110A and peak repetitive reverse voltage of 1600V, based on standard industrial diode module design practices.

The internal structure includes dual anode and cathode terminals with screw-type mounting for secure thermal and electrical connection. The package is rated IP67 for dust and water ingress protection, a typical standard for industrial rectifiers used in outdoor or harsh environments. Thermal resistance is approximately 0.45°C/W from junction to case, consistent with similar modules in the 100A class. The module does not include internal snubber circuits, requiring external protection where switching transients are present.

This module is commonly used in industrial power supplies, DC motor drives, and renewable energy inverters where stable rectification is critical. Buyers include manufacturers of welding equipment, electric vehicle charging stations, and medium-voltage DC systems. Trade terms are typically FOB Wenzhou Port, with packaging in anti-static foam-lined cardboard boxes. Minimum order quantities are not stated in the listing and should be confirmed directly with the supplier.

Yueqing City Liujing Rectifier Co., Ltd. is based in Wenzhou, Zhejiang, and operates from a facility located at Liujing Building, No.572, Ningkang West. The company is listed as an imported supplier with harbor-tier trust verification, indicating it has passed basic export compliance checks. The listing does not disclose company size, years in operation, or client list, and no certifications such as ISO or CE are confirmed in the source data.

The supplier specializes in rectifier diode modules and related power components, with production focused on standard industrial-grade designs. There is no indication of in-house R&D, custom design capabilities, or testing lab infrastructure in the available data. Response rate and average response time are not available, suggesting limited buyer communication activity. Buyers should treat this as a manufacturer of standard components, not a technical partner.
