1N5267

Single Zener Diodes Overview

The SMC Diode Solutions 1N5267 is a silicon planar Zener diode housed in the DO-35 glass axial leaded package. It provides a nominal Zener voltage of 75 V with a maximum DC power dissipation of 0.5 W at 25°C ambient temperature. The device utilizes a glass passivated junction chip for reliability and operates within a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix (e.g., B for ±5%, A for ±10%) required for your design, as standard availability varies by manufacturer lot. Confirm RoHS compliance status if restricted substances are prohibited in your assembly process. Ensure the DO-35 footprint matches your PCB layout constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 75 V reference is needed in an axial package. Verify that the 0.5 W power rating accommodates the expected thermal environment without excessive derating. Check if tighter tolerances or surface mount alternatives like the 1N5267BUR-1 are necessary for automated assembly or space-constrained designs.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5267 series of small signal Zener diodes. The series covers voltages from 2.4 V to 75 V, sharing identical physical packages and general electrical characteristics while differing primarily in breakdown voltage specifications.

Single Zener Diodes Replacement Considerations

Cross-reference with 1N5267B or 1N5267D-BP for equivalent DO-35 performance. Surface mount equivalents include the 1N5267BUR-1. Verify pinout compatibility and thermal resistance differences when substituting manufacturers.
