Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging and terminal plating specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the component marking code with official Littelfuse documentation to authenticate the source and prevent counterfeit procurement risks.

Diode Arrays Selection Notes

Select this component when a dual common cathode arrangement is required to minimize board space compared to discrete single diodes. Ensure the application current does not exceed the 40 A average forward current rating under specified thermal conditions. Verify that the system voltage remains below the 100 V repetitive reverse voltage limit to maintain reliable operation.
