W04M

Overview

The GeneSiC Semiconductor W04M is a single-phase silicon bridge rectifier rated for a maximum average forward rectified current of 1.5 A at an ambient temperature of 50 °C. It supports a maximum recurrent peak reverse voltage of 400 V and a maximum RMS voltage of 280 V. The device exhibits a maximum instantaneous forward voltage of 1.0 V at 1.5 A and can withstand a peak forward surge current of 40 A under JEDEC testing conditions. Operating junction temperatures range from -55 °C to +125 °C, with storage capabilities extending up to +150 °C.

Feature Summary

• Surge overload ratings provide protection against transient currents up to 40 amperes peak.
• Designed for reliable low-cost construction using molded plastic cases and solder-plated leads.
• Guaranteed high-temperature soldering capability at 260 °C for ten seconds.

Applications

• Printed circuit board mounting
• General-purpose rectification in power supplies

Procurement Notes

Verify the manufacturer designation carefully, as the W04M part number appears across multiple vendors including Rectron and Gulf Semiconductor. Confirm that the specific datasheet matches the required electrical parameters, particularly the 40A surge rating versus other variants. Ensure compliance with RoHS standards if applicable to the assembly process.

Selection Notes

Select this component when a 1.5 A continuous current and 400 V blocking voltage are required in a through-hole package. Consider derating the forward current by 20% if the load is capacitive. Verify thermal resistance requirements based on copper pad dimensions and lead length during PCB layout.

Part Context

The W04M belongs to the W005M through W10M series of single-phase silicon bridge rectifiers. This family shares identical physical dimensions and mechanical data, differing primarily in their voltage ratings which range from 50 V to 1000 V. All variants maintain a consistent 1.5 A current rating and similar thermal characteristics.

Replacement Considerations

Cross-reference with W04G or W04P from other manufacturers. Verify that substitute components match the 1.5 A current rating, 400 V reverse voltage, and DOB-4 package footprint to ensure mechanical compatibility.
