Diode Arrays Procurement Notes

Verify the specific ordering code suffix when sourcing components. The standard designation corresponds to the base part number, while the addition of an 'H' suffix indicates that the unit has passed AEC-Q101 automotive qualification standards. Confirm packaging details, as the standard configuration utilizes tubes containing fifty units per package. Ensure compliance with RoHS directives and halogen-free requirements according to IEC 61249-2-21 during procurement.

Diode Arrays Selection Notes

Select this component for circuits requiring a 50 V blocking voltage and 25 A continuous current handling capacity. The ITO-220AB package facilitates mounting on heat sinks via the central tab, which serves as the cathode connection. Consider the thermal resistance characteristics for proper heatsink design to maintain junction temperatures within the specified operational limits under varying load conditions.
