Diode Arrays Procurement Notes

Verify the specific package variant required, as the base part number covers both D2PAK (TO-263AB) and TO-262AA configurations. Confirm the suffix indicates the correct orientation and packaging format, such as tube or tape and reel, to match assembly requirements. Ensure compliance with RoHS3 and halogen-free standards if mandated by the design specifications.

Diode Arrays Selection Notes

Select this component for applications requiring fast switching speeds and low conduction losses. The 200 V rating suits low-voltage DC conversion stages. Evaluate thermal management needs based on the specified thermal resistance values. Consider the common cathode topology for synchronous rectification or bridge-less PFC circuits where dual diode integration is beneficial.

Diode Arrays Part Context

This device belongs to the MURB series of ultrafast recovery rectifiers from Vishay. The series utilizes FRED Pt technology to optimize performance between forward voltage drop and recovery speed. It serves as a modern replacement for standard ultrafast diodes in high-frequency power electronics, offering improved efficiency through reduced switching losses.
