Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration when sourcing. Confirm the DO-213AA-2 package dimensions match your PCB footprint requirements. Ensure the ±5% voltage tolerance aligns with your circuit design specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a fixed 5.1 V reference is required in space-constrained designs. The low leakage current makes it suitable for precision applications. Consider the thermal rating if the device will operate in environments exceeding standard industrial temperatures.

Single Zener Diodes Part Context

This part belongs to the CDLL52xx series of hermetic Zener diodes from Microchip. These components are commonly used in military and aerospace-grade electronics due to their robust construction and wide temperature stability. The series offers various voltage options within the same physical package form factor.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-213AA-2 packaged Zener diodes rated at 5.1 V ±5%. Verify that substitute parts meet the same 175°C maximum junction temperature and leakage current specifications to ensure functional compatibility.
