Diode Arrays Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE suffix indicates lead-free plating compliance. Confirm the exact part number matches the intended pinout and marking code (CA6E) for the common cathode variant. Ensure the procurement source provides official datasheets to validate the enhanced specification ratings.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required in a compact SOT-23 footprint. The enhanced specifications offer improved performance over standard variants, specifically regarding breakdown voltage margins and forward voltage characteristics. Consider the thermal resistance and power dissipation limits relative to the expected operating conditions and ambient temperature constraints.

Diode Arrays Part Context

This component belongs to the CMPD2836E/CMPD2838E series of enhanced specification surface mount dual silicon switching diodes. It serves as an upgraded version of the legacy CMPD2838, offering tighter electrical tolerances and improved reliability metrics while maintaining the same physical package dimensions and pin configurations for direct board-level compatibility.

Diode Arrays Replacement Considerations

Direct replacements must match the dual common cathode topology and SOT-23 package. Verify that substitute components meet or exceed the 120V reverse voltage rating and 200mA forward current capability. Check for equivalent reverse recovery times and forward voltage drops to ensure circuit performance consistency.
