1N4116UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4116UR-1 is a 500 mW metallurgically bonded glass surface mount Zener diode in the DO-213AA package. It provides a nominal Zener voltage of 24 V with a standard tolerance of ±5%. The device operates within a junction and storage temperature range of -65 °C to +175 °C. Key electrical parameters include a maximum dynamic impedance (ZZT) of 0.01 Ohms, a maximum reverse current (IR) of 18.3 µA at 21.3 V, and a maximum noise density of 40 µV/√Hz.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Hermetically sealed glass DO-213AA surface mount package
• Qualified per MIL-PRF-19500/435 up to JANS level

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific qualification level required for your application, as this part number series supports JAN, JANTX, JANTXV, and JANS levels under MIL-PRF-19500/435. Confirm that the ordering suffix matches the desired screening grade. Ensure compatibility with the specified DO-213AA footprint and polarity markings during integration.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener regulator is needed for harsh environments. The internal metallurgical bond offers superior stability compared to standard packages. Consider the thermal derating curve if operating near the upper temperature limit of 175 °C.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of 0.5 W glass surface mount Zener diodes. These parts serve as the surface mount equivalent to the JEDEC registered axial-leaded 1N4099 through 1N4135 series, providing a direct pin-compatible alternative for designs transitioning from through-hole to surface mount technologies.

Single Zener Diodes Replacement Considerations

Direct equivalents include the CDLL4116-1 designation. Other variants within the same family are available with different voltage ratings or tighter tolerances using suffixes such as 'C' for 2% or 'D' for 1%.
