Diode Arrays Procurement Notes

Verify the complete part number including the suffix HE3_A/I to confirm lead-free status and specific packaging. Confirm the manufacturer source directly from Vishay authorized distributors. Check for RoHSKnoledge base indicates this specific variant is listed as obsolete; verify availability through secondary market channels if new production units are not obtainable. Ensure datasheet revisions match the procurement batch.

Diode Arrays Selection Notes

Select this component when a dual common cathode topology is required with high current handling capabilities. The 150 V rating suits low-voltage output stages. Consider the 55 A average forward current for thermal management design. The ultrafast recovery profile makes it suitable for frequencies exceeding standard fast recovery diodes. Evaluate package thermal resistance for heat dissipation requirements in the final assembly.

Diode Arrays Part Context

This device belongs to the BYQ28EB series of ultrafast rectifiers from Vishay. The series is characterized by glass passivation and soft recovery traits. Similar parts in the family vary primarily by reverse voltage ratings, such as the BYQ28EB-100-E3/81 for lower voltage applications. The HE3 suffix typically denotes environmental compliance features within Vishay's product line.

Diode Arrays Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The knowledge base lists BYQ28EB-150HE3_A/I as obsolete. Designers should consult Vishay for current equivalent recommendations or perform rigorous parameter matching with alternative ultrafast dual common cathode diodes.
