BYQ28EF-100-E3/45

Diode Arrays Overview

The BYQ28EF-100-E3/45 is a dual common cathode ultrafast rectifier manufactured by Vishay General Semiconductor. It utilizes glass passivated chip junctions to achieve ultrafast recovery times and soft recovery characteristics, ensuring low switching losses and high efficiency. The device features high forward surge capability and is housed in an ITO-220AB (TO-220F) plastic package with matte tin plated leads. It meets MSL level 1 per J-STD-020 and complies with RoHS 2002/95/EC and WEEE 2002/96/EC directives.

Diode Arrays Feature Summary

• Glass passivated chip junction for enhanced reliability
• Ultrafast recovery times with soft recovery characteristics
• Low switching losses and high efficiency operation
• High forward surge current capability

Diode Arrays Applications

• Low voltage, high frequency rectification in switching power supplies
• Freewheeling diodes in DC-to-DC converters
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific electrical parameters, such as peak reverse voltage and average forward current, against the official Vishay datasheet for the BYQ28EF series before integration. Confirm that the E3 suffix denotes consumer grade compliance with lead-free requirements and whisker testing standards. Ensure the TO-220F package dimensions match the target PCB footprint and thermal management design constraints.

Diode Arrays Selection Notes

Select this component for designs requiring fast switching speeds and minimal reverse recovery charge in low-voltage environments. The dual common cathode configuration simplifies circuit layout for bridge or synchronous rectifier topologies. Consider the thermal performance of the ITO-220AB package for heat dissipation requirements under continuous load conditions.

Diode Arrays Part Context

This part belongs to the BYQ28E(F,B)-100 thru BYQ28E(F,B)-200 family of dual common cathode ultrafast rectifiers from Vishay. The series is designed for general-purpose high-speed rectification. The E3 suffix indicates standard consumer-grade packaging and material compliance, distinguishing it from higher-reliability variants like the HE3 series which may offer automotive qualification.

Diode Arrays Replacement Considerations

Direct substitutes within the same Vishay family include BYQ28EF-200-E3/45 for higher voltage ratings. Cross-manufacturer equivalents should be verified for matching pinout, current handling, and reverse recovery time specifications.
