Diode Arrays Applications

• High speed switching circuits
• General purpose signal processing
• Digital logic interface protection

Diode Arrays Procurement Notes

Verify the specific ordering suffix required for your manufacturing needs. The standard lead-free designation requires adding PBFREE to the part number. Tin/lead plating options require the TIN/LEAD suffix. Confirm availability status as this component family may be subject to discontinuation notices or end-of-life classifications depending on the specific package variant ordered.

Diode Arrays Selection Notes

Select this component when a dual isolated diode solution is required in a small footprint. Ensure the 120 V reverse voltage rating meets the circuit requirements. Verify that the SOT-563 pinout matches the design schematic, specifically noting the non-connected pins and the specific anode/cathode arrangement for each internal diode.

Diode Arrays Part Context

This component belongs to the Central Semiconductor line of surface mount switching diodes. It utilizes the epitaxial planar process for manufacturing. The device is distinct from single-diode variants like the CMSD4448 due to its dual isolated architecture and six-pin SOT-563 packaging format.
