Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation as SMC Diode Solutions may utilize different part numbering conventions than standard JEDEC codes. Confirm RoHS compliance status and packaging options directly with authorized distributors. Ensure the DO-204AH package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a 36 V regulation point is required in a through-hole design. The 500 mW power rating suits low-current stabilization tasks. Consider the wide temperature range for industrial environments. Verify that the axial lead configuration fits the assembly process compared to surface-mount alternatives like the MMSZ series.

Single Zener Diodes Part Context

This device belongs to the standard 1N52xx series of Zener diodes, widely used for general-purpose voltage regulation. The 'B' suffix typically denotes a 5% voltage tolerance band. It serves as a fundamental discrete semiconductor component for basic circuit protection and biasing functions in analog electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes include Vishay 1N5258B-T and Microchip Technology 1N5258B. Surface-mount equivalents such as Diodes Incorporated MMSZ5258B-7-F offer similar electrical characteristics but require SMD assembly processes. Verify pinout compatibility and thermal derating curves when cross-referencing.
