Overview
The MDD 2W04 is a single-phase bridge rectifier from the WOM series, designed for converting alternating current to direct current. It features a maximum repetitive peak reverse voltage of 400V and an average forward rectified current rating of 2A. The device utilizes a glass-passivated junction for reliability and low reverse leakage. It is housed in a plastic package that meets UL 94V-0 flammability standards, suitable for printed circuit board applications with high thermal stability.
Feature Summary
- Glass-passivated junction ensures low reverse leakage current
- Plastic package complies with UL 94V-0 flammability ratings
- High surge current capability for robust operation
- Designed for through-hole mounting on printed circuit boards
Applications
- AC to DC power supply conversion circuits
- General-purpose rectification in electronic devices
- Printed circuit board based power modules
Procurement Notes
Verify the manufacturer part number 2W04 against official MDD documentation to ensure authenticity. Confirm the WOM package type and pin configuration match your PCB footprint requirements. Check datasheet specifications for thermal resistance and operating temperature range to validate suitability for your specific environmental conditions before procurement.
Selection Notes
Select this component when a 400V reverse voltage and 2A continuous forward current are required. Ensure the application supports through-hole technology as the device is not surface-mount compatible. Verify that the expected surge currents remain within the specified limits to prevent device failure during transient events.
Part Context
The 2W04 belongs to the WOM series of silicon bridge rectifiers manufactured by MDD (Microdiode Semiconductor). This series is characterized by its standard through-hole packaging and reliable performance in general-purpose rectification tasks. It serves as a fundamental passive component in power electronics infrastructure.
Replacement Considerations
Publicly confirmed equivalent part numbers include KBP04, MB6S, and GBU4. These substitutes offer similar electrical ratings and may be considered if the original part is unavailable, provided mechanical compatibility is verified.
