Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required termination finish (TIN/LEAD) and packaging style (BK). Confirm RoHS compliance status as leaded variants may differ from standard environmental directives. Ensure the DO-35 package dimensions align with the target PCB footprint before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 3.3 V reference is required in a through-hole assembly. The high maximum operating temperature of 200 °C allows for use in harsh thermal environments where standard silicon limits are exceeded. Verify that the 250 mW power rating suffices for the expected load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4620 series of low-power Zener diodes produced by Central Semiconductor. These components are typically utilized in general-purpose electronic designs requiring reliable voltage clamping or referencing. The DO-35 package offers a compact form factor suitable for dense board layouts.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4620 specifications. Ensure substitute parts maintain the 3.3 V Zener voltage, 250 mW power rating, and DO-35 package compatibility.
