Procurement Notes
Verify the specific suffix configuration against the datasheet to ensure correct tolerance and packaging options. Confirm RoHS compliance status if required by the application, as indicated by the e3 suffix. Check thermal resistance requirements relative to the FR4 PCB footprint and copper weight specified in the mechanical data.
Selection Notes
Select this component for applications requiring a 5.1 V reference in a compact surface mount form factor. Ensure the operating current remains within the specified limits to maintain regulation accuracy. Consider the thermal derating curve when designing for ambient temperatures exceeding 25°C or end-cap temperatures above 100°C.
Part Context
This part belongs to the 1N4614UR through 1N4627UR series of 0.5 W glass surface mount Zeners. It serves as the surface mount equivalent to the JEDEC registered axial-leaded 1N4625 diode. The series offers voltages from 1.8 to 100 V with various tolerance options.
Replacement Considerations
Direct replacement equivalents include the axial-leaded 1N4625 and the MLL4625. Verify pinout compatibility and thermal management capabilities when substituting with other surface mount packages.
