Procurement Notes

Verify the specific suffix _S00Z against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure that the ordering information matches the exact part number required for your bill of materials. Cross-reference the datasheet revision date to guarantee access to the most current technical specifications and reliability data before finalizing procurement.

Selection Notes

Select this component when an 11 V reference is required in a through-hole design. The 1 W power rating allows for robust performance in moderate current applications. Consider the DO-41 package dimensions for PCB layout constraints. Verify that the operating temperature range meets the specific environmental requirements of the target application system.

Part Context

This component belongs to the standard 1N47xxA series of glass-passivated silicon Zener diodes. These devices are widely used for general-purpose voltage regulation and clipping applications. The 1N4741A designation specifically identifies the 11 V variant within this extensive family of discrete semiconductor components manufactured by onsemi.

Replacement Considerations

Compatible substitutes include the 1N4741A from other manufacturers such as Nexperia or Taiwan Semiconductor, provided they meet the same 11 V, 1 W, and DO-41 package specifications. Ensure that any replacement part maintains equivalent electrical parameters and thermal ratings.
