Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details such as tape and reel or cut tape configurations. Confirm RoHS compliance status and ensure the component meets all relevant environmental regulations required for your specific manufacturing process before finalizing procurement orders.

Selection Notes

Select this component when a precise 4.7 V reference is needed in through-hole designs. Ensure the circuit design accommodates the specified differential resistance and test current requirements. Verify that the thermal management strategy aligns with the 1 W power dissipation limit under expected ambient conditions.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes produced by Nexperia. The series offers various nominal working voltages ranging from 3.3 V to 24 V, all utilizing the same SOD66 axial leaded package format. This standardization simplifies inventory management for designs requiring multiple voltage levels.

Replacement Considerations

Direct replacements include other manufacturers' 1N4732A variants. Verify pinout compatibility and electrical parameter equivalence, specifically the Zener voltage tolerance and power rating, before substituting.
