2W04M

Bridge Rectifier Overview

The GeneSiC Semiconductor 2W04M is a single-phase silicon bridge rectifier in the WOB package. It provides a maximum average forward rectified current of 2.0 A at 50°C ambient temperature and supports a maximum recurrent peak reverse voltage of 400 V. The device features a peak forward surge current rating of 50 A for an 8.3 ms half-sine wave. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 2.0 A, with reverse leakage currents specified at 10 µA at 25°C and 500 µA at 125°C. Thermal resistance values are 40°C/W (junction-to-ambient) and 15°C/W (junction-to-lead).

Bridge Rectifier Procurement Notes

Verify component authenticity by checking for UL recognition file number E-96005 on the datasheet or official manufacturer documentation. Confirm that the ordering suffix matches the specific voltage rating required for the application. Ensure procurement sources provide valid traceability records consistent with GeneSiC Semiconductor manufacturing standards.

Bridge Rectifier Selection Notes

Select the 2W04M when a 400 V blocking voltage is necessary for single-phase rectification. The 2.0 A continuous current rating suits low-power applications. Consider thermal derating curves if operating above 50°C ambient temperature. Verify lead length requirements for PCB mounting to ensure accurate thermal resistance calculations.

Bridge Rectifier Part Context

This component belongs to the 2W005M through 2W10M series of single-phase silicon bridge rectifiers. All variants share identical mechanical dimensions and current ratings, differing only in their maximum repetitive peak reverse voltage capabilities ranging from 50 V to 1000 V.

Bridge Rectifier Replacement Considerations

Compatible substitutes must match the 2.0 A current rating, 400 V reverse voltage, and WOB package style. Verify equivalent thermal resistance and surge current specifications before implementation.

Bridge Rectifier FAQ

What is the maximum non-repetitive forward surge current?

The peak forward surge current is rated at 50 A for an 8.3 ms single half-sine wave superimposed on the rated load.

How does the device handle capacitive loads?

For capacitive loads, the average forward current should be derated by 20% compared to resistive or inductive load conditions.

What are the storage temperature limits?

The storage temperature range extends from -55°C to +150°C.
