W01M

Overview

The GeneSiC Semiconductor W01M 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 features a maximum recurrent peak reverse voltage and DC blocking voltage of 100 V, with a corresponding maximum RMS voltage of 70 V. The device exhibits a maximum instantaneous forward voltage of 1.0 V at the rated current and supports a peak forward surge current of 40 A under JEDEC testing conditions. Electrical characteristics are defined within an operating junction temperature range of -55 to +125 °C.

Feature Summary

• Surge overload ratings provide protection against transient current peaks up to 40 amperes peak.
• Construction is optimized for printed circuit board mounting applications.
• Guaranteed high-temperature soldering capability ensures reliability during assembly processes.

Applications

• General purpose AC-to-DC full-wave rectification in switching power supplies
• Bridge rectifier circuits for low-voltage consumer electronics
• Power supply stages requiring 100 V reverse voltage blocking

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer marking with the official datasheet specifications. Confirm that the package type matches the required PCB footprint dimensions. Ensure compliance with relevant environmental directives such as RoHS if applicable to the specific production batch. Check thermal resistance parameters against system cooling requirements before final integration.

Selection Notes

Select the W01M when the circuit requires a 100 V reverse voltage rating and a continuous current capacity of 1.5 A. Consider derating the forward current by 20% if the load is capacitive rather than resistive or inductive. Evaluate the thermal environment to ensure the junction temperature remains within the specified -55 to +125 °C range during operation.

Part Context

The W01M belongs to the W005M through W10M series of single-phase silicon bridge rectifiers manufactured by GeneSiC Semiconductor. This family shares identical mechanical data and electrical performance profiles, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50 V to 1000 V across the series variants.

Replacement Considerations

Compatible substitutes include other W01M variants from different manufacturers such as Taiwan Semiconductor or Gulf Semiconductor, provided they meet the 1.5 A current and 100 V reverse voltage specifications. Verify pinout compatibility and physical dimensions to ensure direct replacement without PCB modification.
