Diode Arrays Procurement Notes

Verify the specific ordering suffix 'CR' against official Littelfuse documentation to confirm the common anode configuration and ITO-220AB packaging format. Ensure that thermal management requirements align with the specified junction-to-case thermal resistance values provided in the datasheet before finalizing procurement specifications.

Diode Arrays Selection Notes

Select this component for designs requiring high-frequency switching and low conduction losses. The dual-leg common anode topology simplifies circuit layout for polarity protection or synchronous rectification applications. Evaluate thermal dissipation needs based on the 5.0 °C/W junction-to-case resistance per leg under DC operation conditions.

Diode Arrays Part Context

This part belongs to the Littelfuse DST series of Ultra Low VF Schottky Barrier Rectifiers.
