Procurement Notes
Verify the manufacturer origin, as Fairchild Semiconductor assets were acquired by onsemi. Ensure the specific suffix matches the required tape and reel or cut tape format. Confirm RoHS compliance status and check for any obsolescence notices related to the legacy Fairchild part numbering system before finalizing procurement.
Selection Notes
Select this component when a dual diode solution with high voltage ratings is required in a small footprint. Compare specifications against similar parts like the MMBD1403 or MMBD1404A to ensure compatibility with voltage and current requirements. Verify that the SOT-23-3 package fits the PCB layout constraints and thermal management needs of the target application.
Part Context
This component belongs to the MMBD140x series of small signal switching diodes. These devices are designed for high-speed switching and general-purpose rectification. The series is widely used in consumer electronics and industrial equipment where reliable performance in a miniature package is essential. Fairchild Semiconductor was a primary supplier before its semiconductor division became onsemi.
Replacement Considerations
The MMBD1403 is a direct functional equivalent. The MMBD1404A shares identical electrical specifications but may differ in manufacturing lot or minor parameter tolerances. Verify pinout compatibility and package dimensions when substituting.
