1N4116-1

Single Zener Diodes Overview

The Microchip Technology 1N4116-1 is a 500 mW metallurgically bonded glass Zener diode in an axial-lead DO-35 package. It provides a nominal Zener voltage of 24 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C and features a maximum dynamic impedance of 150 Ω at a test current of 250 µA. Reverse leakage current is limited to 10 nA at 18.3 V, while the maximum regulator current reaches 16 mA.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
• Hermetically sealed glass DO-35 (DO-204AH) package
• Inherently radiation hard

Single Zener Diodes Applications

• High-reliability military applications
• Spacecraft systems requiring JANS qualification
• Voltage regulation over broad current and temperature ranges
• Low-noise reference circuits

Single Zener Diodes Procurement Notes

Verify the specific reliability level required, as the part number suffix indicates the qualification grade. Confirm RoHS compliance status, noting that compliant versions are available only on commercial grades. Ensure the ordering suffix matches the desired tolerance and lead finish specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when high reliability and radiation hardness are critical requirements. The metallurgical bond offers superior performance compared to standard glass passivation. Consider the negative temperature coefficient for voltages below 6.8 V and positive coefficients above 6.8 V when designing temperature-stable references.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener diodes. These devices share the same DO-35 package and metallurgical bond technology but vary in nominal voltage from 1.8 V to 100 V. They serve as JEDEC registered equivalents to the non-bonded 1N4099 through 1N4135 series.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4116 variants with matching voltage and power ratings. Verify that substitute parts meet the same MIL-PRF-19500/435 qualification levels if military or aerospace reliability is required.
