Single Zener Diodes Procurement Notes

This component is officially obsolete and discontinued by the manufacturer. Verify availability through authorized distributors or secondary markets. Confirm that replacement components meet all original electrical specifications and mechanical requirements before integration into existing designs.

Single Zener Diodes Selection Notes

Select this part only if legacy compatibility is required. For new designs, consider surface mount equivalents such as MMSZ52xxB series. Ensure thermal derating is applied if operating above 75°C ambient temperature to maintain reliability within specified limits.

Single Zener Diodes Part Context

Part of the 1N5221B-1N5267B series offering voltages from 2.4V to 200V. Manufactured using epitaxial technology for improved stability compared to standard junctions. The DO-35 package is a standard axial leaded form factor widely used in through-hole applications.

Single Zener Diodes Replacement Considerations

Manufacturer recommends using MMSZ52xxB series as direct replacements. Verify pinout compatibility and power dissipation ratings when substituting with surface mount variants.
