Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official documentation before procurement. Confirm that the HE3 designation aligns with RoHS compliance requirements and AEC-Q101 qualification standards. Ensure the ordering code matches the required tolerance level and packaging format specified in the manufacturer's latest datasheet.

Single Zener Diodes Selection Notes

Select this component when a 39 V Zener voltage is required in an SMA package. Consider the 29.7 Ω dynamic resistance and 5 µA reverse current limits for precision applications. Evaluate thermal management needs as power dissipation decreases with increasing terminal temperature above 75 °C.

Single Zener Diodes Part Context

This device belongs to the SML4728 to SML4764A series of surface mount Zener diodes. The series covers a wide range of nominal voltages from 3.3 V to 100 V. All variants share the same DO-214AC mechanical footprint and similar electrical characteristics tailored to their specific voltage ratings.

Single Zener Diodes Replacement Considerations

Cross-reference with other SML4754 variants or equivalent 39 V Zener diodes in the DO-214AC package. Verify matching dynamic resistance and reverse current specifications to ensure circuit compatibility.
