Diode Arrays Procurement Notes

Verify the specific ordering code suffix against official Vishay documentation to confirm compliance status. The base part number indicates RoHS compliance and halogen-free construction. Confirm that the requested variant matches the required automotive qualification if applicable, as standard and qualified versions share similar electrical characteristics but differ in certification.

Diode Arrays Selection Notes

Select this component for designs requiring high current density in a compact surface-mount footprint. Ensure thermal management accounts for the specified junction-to-ambient resistance when operating without an infinite heatsink. Validate that the application's peak reverse voltage does not exceed the 45 V rating under all transient conditions.

Diode Arrays Part Context

This device belongs to Vishay's eSMP series of high-efficiency Schottky rectifiers. It is designed to replace traditional PN junction rectifiers in applications where switching speed and forward voltage drop are critical performance factors. The SlimDPAK package provides robust mechanical stability and efficient heat dissipation capabilities.
