Overview
The RURD3040 is a dual common-cathode avalanche diode array manufactured by Harris Corporation. It features an average rectified current of 30A per diode and a repetitive peak reverse voltage of 400V. The device utilizes silicon technology with a fast recovery speed, characterized by a reverse recovery time of 60ns. Designed for through-hole mounting, it is housed in a TO-218-3 package with an isolated tab configuration.
Feature Summary
- Incorporates avalanche technology for enhanced ruggedness
- Features fast recovery characteristics suitable for high-speed switching applications
- Provides a common cathode configuration for simplified circuit design
Applications
- High-voltage power supply circuits
- Inductive load protection networks
- Fast switching rectification tasks
Procurement Notes
Verify the manufacturer origin carefully, as Harris Corporation assets were acquired by Microchip Technology. Ensure the specific suffix matches the required package variant. Confirm that the avalanche rating aligns with the system's transient energy requirements before finalizing procurement orders.
Selection Notes
Select this component when a 30A current capacity and 400V blocking voltage are required in a single dual-diode package. The TO-218-3 isolated tab facilitates thermal management and electrical isolation from heatsinks. Consider the 60ns reverse recovery time for compatibility with the target switching frequency.
Part Context
This part belongs to the Harris Corporation diode array family, specifically designed for robust power electronics. The series emphasizes high-current handling and voltage resilience. It serves as a discrete solution for rectification and clamping duties in industrial and commercial power conversion systems.
Replacement Considerations
Microchip Technology acquired Harris semiconductor assets; therefore, Microchip-branded equivalents may be available. Verify pinout compatibility and thermal resistance specifications against potential substitutes to ensure seamless integration without circuit modification.
