Single Zener Diodes Procurement Notes

Verify that the ordering suffix '-G' corresponds to RoHS compliance as indicated by the datasheet title. Confirm the manufacturer is Comchip Technology CO., LTD. Ensure the component matches the DO-35 axial leaded glass package specifications before integration into designs.

Single Zener Diodes Selection Notes

Select this component when a standard 16 V Zener reference is required in an axial through-hole configuration. The positive temperature coefficient makes it suitable for applications where voltage increases with temperature. Verify that the 500 mW power dissipation rating meets the thermal requirements of the target circuit environment.

Single Zener Diodes Part Context

This part belongs to the 1N5221B-G through 1N5267B-G series of axial-leaded glass Zener diodes manufactured by Comchip Technology. The series covers a wide range of nominal voltages from 2.4 V to 75 V, all sharing the same 500 mW power dissipation capability and DO-35 package form factor.

Single Zener Diodes Replacement Considerations
