Procurement Notes

Verify the specific suffix R1 against official manufacturer documentation to confirm reel packaging specifications and tape dimensions. Confirm AEC-Q101 qualification status directly with the supplier or original datasheet before integration into automotive designs. Ensure the DO-41 package dimensions match the target PCB footprint requirements. Cross-reference the part number with the latest production change notices to verify material compliance and manufacturing origin details.

Selection Notes

Select this component when a 160 V regulation point is required in high-reliability environments. The 1 W power rating supports moderate current loads in axial packages. Verify that the 1.1 kΩ impedance meets the noise sensitivity requirements of the circuit. Compare thermal performance against alternative packages if space constraints exist. Ensure the operating temperature range aligns with the specific environmental conditions of the end application.

Part Context

This part belongs to the 1MxxxZH series of Zener diodes from Taiwan Semiconductor. The series utilizes a DO-41 axial glass encapsulation suitable for automated assembly processes. These devices are engineered for robust performance in demanding industrial and automotive sectors. The family offers various voltage options while maintaining consistent mechanical and electrical characteristics across the range.

Replacement Considerations

Direct substitutes must match the 160 V Zener voltage, 1 W power rating, and DO-41 package. Verify equivalent AEC-Q101 qualification for automotive replacements. Check for identical impedance and leakage current specifications to ensure circuit compatibility.
