Procurement Notes

Verify component authenticity and datasheet revisions directly with Taiwan Semiconductor Corporation before integration. Confirm that the specific manufacturing lot meets required quality standards for your application environment. Ensure proper handling procedures are followed during assembly to maintain device integrity and performance specifications.

Selection Notes

Select this component when a robust, high-voltage Zener reference is needed in a standard axial package. The 1W power rating allows for effective heat dissipation in moderate current scenarios. Verify that the 200V breakdown voltage aligns precisely with circuit requirements and that the DO-41 footprint fits the design constraints.

Part Context

This part belongs to the 1M series of Zener diodes from Taiwan Semiconductor, which focuses on general-purpose voltage regulation components. The series offers various voltage options within the DO-41 package, providing designers with standardized solutions for discrete voltage control tasks across diverse electronic equipment categories.

Replacement Considerations

Cross-reference with other manufacturers' DO-41 packaged Zener diodes rated for 200V, 1W, and ±5% tolerance. Ensure equivalent electrical parameters such as Zener impedance and leakage current are compatible. Verify mechanical dimensions match the existing PCB layout for seamless substitution.
