Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required plating type, as tin/lead variants differ from lead-free options. Confirm the axial lead form factor aligns with the target PCB footprint. Ensure the 1.5 W power rating meets the thermal requirements of the intended application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 15 V Zener reference is required in an axial package. The DO-41 housing supports standard through-hole assembly processes. Consider the 1.5 W dissipation limit to ensure adequate heat sinking if operating near maximum ratings. Verify compatibility with existing circuit impedance and current limits.

Single Zener Diodes Part Context

This part belongs to the broader category of glass and silicon Zener diodes used for voltage control. Similar devices include the JAN1N4469US and other 1N4469 variants from manufacturers like Microsemi and Central Semiconductor. These components share common electrical specifications but may vary in physical packaging or regulatory compliance status.

Single Zener Diodes Replacement Considerations

Direct substitutes include the JAN1N4469US and generic 1N4469 parts from other vendors. Verify pinout compatibility and thermal resistance values. Ensure replacement units meet the same 15 V nominal voltage and 1.5 W power dissipation standards.
