Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as tape and reel quantities or cut tape availability. Confirm RoHS compliance status and REACH registration requirements prior to procurement. Ensure the selected variant matches the required hermetic sealing specifications for the intended environmental conditions.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 4.3 V is required in circuits utilizing axial leaded packages. Consider the thermal resistance from junction to tie-point and the maximum power dissipation limits when designing heat management strategies. Verify that the operating current remains within the specified working current range to maintain accurate voltage regulation performance.

Single Zener Diodes Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series provides nominal working voltages ranging from 3.3 V to 24 V. All devices in this family share the same SOD66 (DO-41) hermetically sealed glass package format and general structural characteristics.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the 1N4731A specification, such as those from Micro Commercial Components (e.g., 1N4731A-TP). Verify pinout compatibility and electrical parameter alignment before substitution.
