1N5269

Single Zener Diodes Overview

The Microchip Technology 1N5269 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 87 V with a tolerance of ±10%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to 175°C. Key electrical characteristics include a maximum Zener impedance of 370 Ohms and a reverse leakage current of 100 nA at 68 V. The forward voltage is specified as 1.5 V at a forward current of 200 mA. The component is housed in an axial-lead DO-204AH (DO-35) package, suitable for through-hole mounting.

Single Zener Diodes Feature Summary

• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 1N5269A or 1N5269B may exist with different tolerances or testing criteria. Confirm RoHS compliance status, as standard versions may not meet current environmental directives. Ensure the required package type matches the PCB footprint design. Cross-reference datasheet specifications against application requirements to confirm suitability for the intended thermal and electrical loads.

Single Zener Diodes Selection Notes

Select this component when a fixed 87 V reference point is required in a through-hole design. Consider the ±10% tolerance for budgeting circuit accuracy. Evaluate the 370 Ohm impedance for dynamic load regulation needs. Compare against lower voltage alternatives if the system requires different reference points. Ensure the 500 mW power rating exceeds the expected operating dissipation under worst-case conditions.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of Zener diodes manufactured by Microchip Technology. The series offers a broad spectrum of voltage ratings from low to high values, all sharing similar physical dimensions and power capabilities. These components are widely used in discrete semiconductor designs where reliable voltage clamping or referencing is essential. The DO-35 package remains a standard form factor for general-purpose electronics assembly.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent substitutes include the base model 1N5269 and the variant 1N5269B. Verify that any replacement maintains the same 87 V nominal voltage and 500 mW power rating. Check that the substitute's impedance and leakage characteristics fall within acceptable limits for the specific application.
