Single Zener Diodes Procurement Notes

Verify the specific suffix BE3 indicates RoHS compliance and lead-free termination when sourcing. Confirm the package type matches DO-7 or DO-204AA specifications for PCB footprint compatibility. Ensure the supplier provides documentation confirming hermetic sealing if required for mission-critical applications. Check for any military screening prefixes if higher reliability levels are needed beyond standard commercial grade.

Single Zener Diodes Selection Notes

Select this component when a 150V Zener voltage is required with tight 5% tolerance. The DO-7 glass package offers superior hermeticity compared to plastic alternatives, making it suitable for demanding environments. Consider the 417mW power rating to ensure adequate thermal management. Verify that the 175°C maximum junction temperature meets the operational requirements of the target system.

Single Zener Diodes Part Context

This part belongs to the 1N5221 thru 1N5281 series of 0.5 watt Zener Voltage Regulators produced by Microsemi/Microchip. The series provides a wide selection of voltages from 2.4V to 200V in standard DO-7 glass axial-lead packages. These components are widely used in applications requiring reliable voltage regulation and protection.

Single Zener Diodes Replacement Considerations

Direct equivalents include 1N5276B and 1N5276B-1E3. Verify that substitute parts maintain the same DO-7 package and hermetic sealing requirements. Ensure replacement components meet the 150V Zener voltage and 5% tolerance specifications.
