Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details such as reel size or tape specifications. Ensure compliance requirements match project needs, including RoHS 2.0 status and UL 94V-0 flammability ratings. Cross-reference datasheet electrical limits with circuit design parameters before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 47 V reference voltage is required in a compact SMA footprint. Evaluate thermal derating curves for ambient temperatures exceeding 50°C to maintain the 1 W rating. Confirm that the 80 Ω impedance and 0.1 µA leakage meet the precision requirements of the target application environment.

Single Zener Diodes Part Context

This part belongs to the 1SMA4728 through 1SMA4757 series, which provides a range of Zener voltages from 3.3 V to 51 V. All members share identical mechanical dimensions, thermal characteristics, and package styles, differing only in their specific breakdown voltage and associated impedance values defined in the series table.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include parts like 1SMA4755 or 1SMA4757 if voltage adjustments are permissible. Verify that any replacement maintains the DO-214AC package and 1 W power rating to ensure physical compatibility.
