Single Zener Diodes Procurement Notes

Verify the specific suffixes against official documentation to confirm exact specifications. The 'H' suffix indicates AEC-Q101 qualification, while 'G' denotes the use of green halogen-free compound. Confirm the packing code matches the required reel size and quantity before procurement.

Single Zener Diodes Selection Notes

Select this component for high-power surface mount applications requiring 3W dissipation in an SMB package. Ensure the circuit design accommodates the specified thermal resistance values and maximum junction temperature limits. Verify that the 47V nominal voltage aligns with the system's regulation requirements.

Single Zener Diodes Part Context

This part belongs to the 1PGSMB5926 through 1PGSMB5956 series from Taiwan Semiconductor. The series covers a wide voltage range from 11V to 200V, all sharing the same 3W power rating and DO-214AA package form factor for consistent board layout across different voltage designs.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include 1PGSMB5940 or 1PGSMB5942 if voltage tolerance allows. For identical specifications, verify availability of other manufacturers' 3W SMB Zener diodes with matching 47V nominal ratings and AEC-Q101 qualifications.
