BYW29E-100,127

Overview

The BYW29E-100,127 is a fast recovery rectifier diode manufactured by WeEn Semiconductors. It features an 8 A forward current rating and a 100 V repetitive peak reverse voltage. The component utilizes a TO-220-2 through-hole package for robust mounting. Key electrical characteristics include a maximum forward voltage of 1.3 V and a reverse recovery time of 25 ns. It supports a maximum surge current of 88 A and operates within a temperature range of -40 °C to +150 °C junction temperature.

Feature Summary

• Fast recovery performance with soft recovery characteristics for reduced switching losses
• Glass passivated die providing high efficiency and reliability under thermal stress
• Low forward voltage drop to minimize conduction losses in power circuits

Applications

• Switched mode power supplies (SMPS)
• High frequency general purpose circuits
• Free-wheeling rectification in inductive loads

Procurement Notes

Verify the specific suffix '127' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the part number corresponds to the 100 V variant rather than other voltage grades within the BYW29E series. Cross-reference RoHS compliance status directly with the latest product specification document provided by WeEn Semiconductors.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse recovery charge. The TO-220-2 package is suitable for applications needing efficient heat dissipation without active cooling. Compare the 100 V rating against circuit peak inverse voltages to ensure adequate safety margins during transient events.

Part Context

This device belongs to the BYW29E series of ultrafast general-purpose rectifiers. The series is characterized by glass passivation and plastic envelope construction. These diodes are engineered for high-efficiency applications where low conduction and switching losses are critical design parameters.

Replacement Considerations

Check for direct substitutes such as the BYW29-100 or equivalent parts from other manufacturers offering identical 8 A / 100 V / TO-220-2 specifications. Verify pinout compatibility and thermal resistance values before substitution.
