Single Zener Diodes Procurement Notes

Verify the specific suffix _S00Z against official onsemi documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets RoHS compliance requirements if applicable to your design constraints. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Single Zener Diodes Selection Notes

Select this component when a standard 18 V reference with moderate precision is required. The DO-35 package offers a compact footprint for general-purpose boards. Consider the thermal derating curve for high-temperature environments to ensure the 500 mW limit is not exceeded. Verify that the 21 Ω dynamic impedance aligns with the noise and stability requirements of the target application circuit.

Single Zener Diodes Part Context

This component belongs to the widely recognized 1N52xx series of Zener diodes, which are industry-standard devices for low-power voltage regulation. The 'B' suffix typically denotes a 5% voltage tolerance, distinguishing it from tighter or looser tolerance variants within the same family. These diodes are commonly used in consumer electronics, industrial controls, and automotive systems where reliable voltage clamping is necessary.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N5248B, Microchip 1N5248B, and Panasonic 1N5248B. Ensure replacement parts match the DO-35 package and 18 V / 500 mW specifications. Verify that alternative manufacturers offer equivalent dynamic impedance and leakage current characteristics.
