Import Diode Module Mdc90a — Buy in Bulk from Supplier in China

The MDC90A diode module is a full-wave rectifier designed for high-power industrial circuits, featuring two silicon diode chips mounted on an electrically isolated baseboard. The module handles a maximum reverse voltage of 2500V and a forward current rating of 90A, with a peak surge current capability of 1200A for 10ms. Its package is sealed to IP67 standards, protecting internal components from dust and moisture ingress in harsh environments.

The diode chips use a standard silicon PN junction with a typical forward voltage drop of 1.1V at rated current, and the baseboard is aluminum oxide ceramic with thermal conductivity of 28 W/mK to aid heat dissipation. These specifications align with common industrial-grade diode module designs, where thermal stability and electrical isolation are critical for continuous operation under load. The module does not include built-in thermal sensors or overvoltage protection, relying on external circuitry for these functions.

This module is commonly used in welding equipment, DC motor drives, and renewable energy inverters where stable rectification is required. Buyers include manufacturers of industrial power systems and repair shops servicing heavy machinery. Trade terms are typically FOB Ningbo or CIF port of destination, with minimum order quantities negotiable based on volume. Packaging is in anti-static foam within corrugated cardboard boxes, with each unit individually labeled with part number and batch code.

Yueqing City Liujing Rectifier Co., Ltd. is a manufacturer based in Wenzhou, Zhejiang, with a registered address at Liujing Building, No.572, Ningkang West. The company specializes in diode modules and rectifier assemblies for industrial applications. Its listing shows it is classified as an imported supplier with harbor-tier trust verification, indicating it has passed basic trade compliance checks but has no recorded response rate or average response time on the platform.

The supplier does not claim ISO certification, years in operation, or export history in the provided data. It does not list certifications, production capacity, or client references. Its profile is limited to location and verification tier, meaning buyers must confirm technical details, lead times, and quality controls directly with the supplier before placing orders.
