Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance requirements and packaging details. Ensure that any additional characters appended to the base part number are explicitly supported by the datasheet before procurement. Confirm RoHS status if environmental compliance is required for the application.

Single Zener Diodes Selection Notes

Select this component when a low-voltage Zener regulator with minimal capacitance and inherent radiation hardness is required. The internal metallurgical bond ensures robust performance in demanding environments. Verify that the 1.8 V breakdown voltage aligns with the circuit's reference needs and that the 500 mW power dissipation rating accommodates the thermal conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4614-1 through 1N4627-1 series of 500 mW Zener voltage regulators. These components are JEDEC registered and available in various reliability levels including JAN, JANTX, JANTXV, and JANS. They utilize a hermetically sealed glass DO-35 package and offer voltages ranging from 1.8 V to 100 V with standard 5% tolerance.

Single Zener Diodes Replacement Considerations

Consult the manufacturer's cross-reference data or equivalent product lists for verified substitutes. Ensure any replacement matches the 1.8 V Zener voltage, 500 mW power rating, and DO-35 package dimensions.
