Single Zener Diodes Procurement Notes

This part number is officially obsolete and discontinued by the manufacturer. Verify availability through secondary distributors or consider alternative sourcing channels. Confirm that any acquired units are genuine and stored correctly to prevent degradation over time.

Single Zener Diodes Selection Notes

Select this component only if legacy compatibility is required. Evaluate surface mount equivalents like the MMSZ52xxB series for modern designs. Ensure thermal management meets the specified junction-to-ambient resistance limits during operation.

Single Zener Diodes Part Context

The 1N5247B belongs to the 1N5221B through 1N5267B series of 500mW Zener diodes. This family provides a wide selection of voltages from 2.4V to 75V in standard DO-35 packages. The 'T' suffix indicates tape and reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Use MMSZ52xxB series components as direct replacements. Verify pinout compatibility and ensure the substitute device meets the original electrical requirements for voltage and power dissipation.
