1N5069

Single Zener Diodes Overview

The Microchip Technology 1N5069 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device is constructed from silicon and utilizes a hermetic, non-cavity glass package, specifically the MELF (O-LELF-R2) form factor with two terminals. It is rated for a power dissipation of 5 W and operates within a temperature range of -65 °C to +175 °C. The component is metallurgically bonded and manufactured in accordance with MIL-PRF-19500/356 standards.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the specific order includes the required military screening per MIL-PRF-19500/356. Confirm the package orientation and terminal finish match the design requirements. Ensure the supplier provides traceability documentation for the hermetic seal integrity. Check for any specific handling instructions related to the glass MELF package during assembly.

Single Zener Diodes Selection Notes

Select this component when high reliability and hermetic sealing are mandatory. The 5 W power rating supports significant current handling in compact packages. The wide temperature range suits extreme environments. Verify that the 7.5 V nominal voltage aligns with the circuit's reference needs. Consider the mechanical constraints of the O-LELF-R2 package footprint.

Single Zener Diodes Part Context

This part belongs to the 1N5069 series of 5 W Zener diodes. It is often associated with manufacturers like Sensitron under similar specifications. The series covers various voltage ratings within the same hermetic glass package family. These components are standard replacements for older military-grade Zener diodes requiring robust construction.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 5 W hermetic Zener diodes meeting MIL-PRF-19500/356. Verify voltage tolerance and package dimensions before substitution. Cross-reference with Sensitron SS4954/US series equivalents if available.
