1N4616-1

Single Zener Diodes Overview

The Microchip Technology 1N4616-1 is a 500 mW Zener voltage regulator diode housed in an axial-lead glass DO-35 package. It provides a nominal Zener voltage of 2.2 V with a standard tolerance of ±5%. The device operates at a test current of 250 µA and features a maximum dynamic impedance of 1300 Ohms. It exhibits a maximum reverse leakage current of 1.0 µA and maintains a temperature coefficient of -0.075 %/°C. Qualified per MIL-PRF-19500/435, it supports reliability levels including JAN, JANTX, JANTXV, and JANS.

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as these are distinct qualification tiers within the same part family. Confirm RoHS compliance status if environmental regulations apply, noting that compliant versions may carry different suffixes. Ensure the ordering nomenclature matches the desired voltage tolerance and metallurgical bonding specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a low-voltage Zener reference near 2.2 V is needed with high stability and radiation hardness. The negative temperature coefficient makes it suitable for compensation purposes. Consider the DO-35 package constraints for through-hole mounting. Evaluate the 500 mW power dissipation limit against thermal derating curves for ambient operating conditions above 25 °C.

Single Zener Diodes Part Context

This device belongs to the 1N4614-1 through 1N4627-1 series of 500 mW metallurgically bonded glass Zener diodes. The series covers voltages from 1.8 V to 100 V. The 1N4616-1 specifically addresses the lower end of this range, offering tight noise density and stable regulation for precision analog circuits requiring robust performance in harsh environments.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' JEDEC registered 1N4616 variants meeting MIL-PRF-19500/435 standards. Verify pinout compatibility and package dimensions (DO-35) to ensure mechanical fit. Cross-reference electrical parameters such as Zener impedance and leakage current to confirm functional equivalence in the target circuit.
