Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' against official ROHM documentation to confirm tape-and-reel packaging configuration. Ensure the part number matches the exact voltage tolerance band required for your circuit design. Cross-reference the AEC-Q101 qualification status if deploying in automotive safety-critical applications. Confirm RoHS compliance details with the latest manufacturer datasheet before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 3.4V is required in a compact SMD footprint. The 500mW power rating allows for higher current handling compared to lower-power variants. Consider the AEC-Q101 qualification if the application involves automotive or harsh industrial environments requiring extended temperature stability and long-term reliability.

Single Zener Diodes Part Context
