Procurement Notes

Verify the specific suffix designation when ordering, as it determines the exact tolerance grade and manufacturing lot. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant matches the required voltage tolerance and package style for the intended design implementation.

Selection Notes

Select this component based on its 6.2 V nominal rating and 500 mW power dissipation capability. Evaluate the thermal environment to ensure the junction temperature remains within the specified operating range. Consider the 30 Ohm impedance value for dynamic regulation performance in the target application circuit.

Part Context

This part belongs to the standard 1N5525 series of low-voltage avalanche Zener diodes manufactured by Microchip Technology. The series offers various voltage options within a consistent DO-35 axial leaded form factor. These components are widely utilized in general-purpose electronics for reliable voltage stabilization tasks.

Replacement Considerations

Equivalent parts from other manufacturers may be considered if they match the 6.2 V Zener voltage, 500 mW power rating, and DO-35 package dimensions. Verify that substitute devices meet the same electrical specifications for leakage current and impedance.
