Diode Arrays Procurement Notes

Verify the specific suffix 'M3/I' to confirm halogen-free compliance and tape-and-reel packaging format. Ensure the application environment remains within the specified thermal limits, as performance depends on heatsinking. Confirm that the 45 V rating aligns with the circuit's peak reverse voltage requirements before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for low-voltage applications. The SMPD package offers a balance between surface-mount convenience and thermal dissipation capabilities. Consider the 1.8 °C/W junction-to-case thermal resistance for heat management design.
