Procurement Notes

Verify the specific suffix 'S2' against official manufacturer documentation to confirm exact packaging or tape-and-reel specifications, as standard datasheets may primarily reference the base model. Ensure compliance with RoHS3 directives and REACH regulations during sourcing. Confirm lead times and availability directly with authorized distributors, as stock levels fluctuate.

Selection Notes

Select this component for applications requiring high current handling in a compact surface-mount footprint. The 135 V rating suits low-voltage DC systems where Schottky diodes minimize conduction losses. Compare thermal resistance and package dimensions against PCB layout constraints. Verify that the 40 A current rating aligns with the system's peak load requirements without exceeding thermal limits.

Part Context

This part belongs to the 89CNQ series of dual Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings including 30V, 40V, 60V, and 150V variants. The 89CNQ135S2 specifically addresses mid-range voltage applications requiring robust current capacity in a standardized surface-mount form factor compatible with industrial and consumer electronics manufacturing processes.

Replacement Considerations
