Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The '/H' suffix indicates a 7-inch diameter plastic tape and reel with a base quantity of 1500 units. Confirm that the component meets RoHS compliance and halogen-free requirements as stated in the datasheet specifications before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component for designs requiring high-frequency operation where minimizing switching losses is critical. The separated cathode configuration allows for independent connection of the two internal diodes. Ensure the application circuit can handle the non-repetitive peak surge current of 173 A per device. Verify thermal management capabilities to maintain the junction temperature within the -55 °C to +175 °C operating range.

Diode Arrays Part Context

This device belongs to Vishay's FRED Pt® family of hyperfast recovery rectifiers. It is designed specifically for output and snubber operations in power conversion systems. The FlatPAK 5 x 6 package provides a compact surface-mount solution suitable for automated assembly processes while maintaining robust thermal performance through its dedicated mounting pads.

Diode Arrays Replacement Considerations

Consult the official Vishay datasheet or authorized distributor databases for verified substitute part numbers. Do not assume cross-compatibility based solely on voltage and current ratings; verify reverse recovery time, forward voltage, and package dimensions to ensure functional equivalence in the target application.

Diode Arrays FAQ

What is the typical reverse recovery time (trr) for the VS-8DKH02-M3?
