Diode Arrays Procurement Notes

Verify the specific ordering suffix required for your plating preference before placing orders. The manufacturer distinguishes between Lead-Free and Tin/Lead plated versions using distinct suffixes appended to the base part number. Confirming this detail ensures compliance with environmental regulations and assembly process requirements. Always cross-reference the latest datasheet revision to ensure compatibility with your design specifications.

Diode Arrays Selection Notes

Select the CMXSTB200 when a stable forward voltage drop is critical for circuit performance compared to standard switching diodes. Its multi-chip architecture provides consistent electrical characteristics suitable for precision analog applications. Ensure the SOT-26 footprint fits the board layout constraints. Consider the thermal management capabilities provided by the 350 mW power dissipation rating during high-current operation phases.

Diode Arrays Part Context

This component belongs to the CMXSTB series, which includes the CMXSTB300 and CMXSTB400 variants.
