Diode Arrays Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm the exact package variant and packing quantity. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure thermal management requirements align with the specified thermal resistance values.

Diode Arrays Selection Notes

Select this component for applications requiring high-frequency switching and low conduction losses. The common cathode arrangement is suitable for synchronous rectification or polarity protection circuits. Evaluate thermal dissipation needs based on the 2.5°C/W junction-to-case resistance and maximum operating temperature limits.

Diode Arrays Part Context

This part belongs to the DST series of ultra-low voltage Schottky barrier rectifiers designed for commercial and industrial use. The series expands Littelfuse's power semiconductor portfolio by offering superior performance compared to traditional silicon switch diodes, specifically targeting efficiency improvements in power conversion systems.

Diode Arrays Replacement Considerations

Check for compatible parts within the same DST series family that share identical electrical ratings and pinout configurations. Verify that any substitute maintains the required common cathode topology and TO-220AB mechanical dimensions for direct board replacement.
