Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as multiple vendors produce this JEDEC part number. Confirm RoHS compliance status and check for any recent product change notices or obsolescence announcements from the supplier. Ensure the package matches the required DO-35 axial lead dimensions for your PCB layout.

Single Zener Diodes Selection Notes

Select this component when a 36 V regulation point is required in an axial through-hole design. Consider the 70 Ω dynamic impedance for noise sensitivity requirements. Evaluate the thermal resistance characteristics if operating near the maximum power dissipation limit in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the 1N5221B-G through 1N5267B-G series of 0.5 W Zener diodes manufactured by Comchip Technology. The series covers a wide voltage range from 2.4 V to 75 V, offering standardized options for various low-power regulation needs in a consistent DO-35 form factor.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5258B parts for equivalent electrical specifications. Verify that substitute components meet the same DO-35 mechanical dimensions and thermal ratings.
