Procurement Notes
Verify the End-of-Life status before design finalization. The manufacturer has issued discontinuation notices. Ensure compatibility with existing inventory or plan for redesign. Check RoHS compliance details through official datasheets. Confirm availability through authorized distributors as standard stock may be limited.
Selection Notes
Select this component when a 4.7 V Zener voltage is required in a small SMD package. Consider the 200 mW power rating for thermal management. Verify that the 80 Ohm impedance meets circuit requirements. Compare against similar Panasonic series like DZ4J068K0R for alternative voltages.
Part Context
This part belongs to the Panasonic DZ4J series of surface mount Zener diodes. These components are designed for high-density PCB layouts. The series offers various voltage options in standardized packages. They are commonly used in automotive and industrial control systems requiring reliable voltage regulation.
Replacement Considerations
Check Panasonic's official replacement list for direct substitutes. Evaluate equivalent parts from other manufacturers based on voltage, package, and power ratings. Ensure pinout compatibility if swapping brands.
