BYQ28EF-100HE3_A/P

Diode Arrays Overview

The BYQ28EF-100HE3_A/P 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, which minimize switching losses and enhance efficiency in high-frequency applications. The device is housed in a TO-220AB plastic package with three pins and complies with RoHS directives. It features high forward surge capability and meets MSL level 1 standards for moisture sensitivity.

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 circuits

Diode Arrays Procurement Notes

Verify the specific suffix HE3_A/P against official Vishay documentation to confirm it denotes the high reliability grade (AEC-Q101 qualified) rather than standard commercial grade. Ensure the ordering code matches the exact package variant required, as suffixes may indicate differences in tape-and-reel packaging or specific qualification levels not always detailed in generic summaries.

Diode Arrays Selection Notes

Select this component for designs requiring fast switching performance in low-voltage environments. The dual common cathode configuration simplifies circuit layout for synchronous rectification or bridge applications. Verify thermal management requirements for the TO-220AB package based on the expected average forward current and ambient operating conditions.

Diode Arrays Part Context

This part belongs to the BYQ28E(F,B)-100 series of dual common cathode ultrafast rectifiers from Vishay. These devices are designed for general-purpose high-efficiency rectification where fast recovery is critical. The series includes variants with different reverse voltage ratings and package options, such as TO-263AB and ITO-220AB, catering to diverse power density and thermal dissipation needs.

Diode Arrays Replacement Considerations

Direct substitutes include other Vishay dual common cathode ultrafast rectifiers like the BYQ28EB-100/81 or BYQ28EF-100/45, provided pinout and electrical ratings match. Cross-brand replacements must be evaluated for equivalent reverse recovery time, forward voltage drop, and package dimensions to ensure compatibility with existing PCB footprints and thermal profiles.
