Single Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct packaging and electrical tolerances. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the assembly process. Cross-reference the ordering part number with authorized distributors to validate authenticity and traceability.

Single Diodes Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage, high-efficiency rectification. The SOD-123 package suits space-constrained designs. Ensure the operating voltage remains below the 40 V rating and thermal management supports the 125°C junction limit. Compare forward voltage characteristics against alternative packages for optimal circuit performance.

Single Diodes Part Context

This device belongs to the MBR HW series of Schottky rectifiers from SMC Diode Solutions. The series provides various voltage ratings and current capacities in small outline packages. The MBR140HW specifically addresses applications needing 40 V blocking capability in a compact form factor suitable for automated surface-mount assembly processes.

Single Diodes Replacement Considerations

Direct substitutes include other 40 V, 1 A Schottky diodes in the SOD-123 package. Verify pinout compatibility and thermal resistance values before substitution. Alternative manufacturers may offer similar specifications but require validation of forward voltage and leakage current parameters.
