Product details
Overview
1N4116-1 from Microsemi is a 500 mW, 24.0 V metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANS level per MIL-PRF-19500/435, with ±5% voltage tolerance, 150 Ω dynamic impedance at 250 mA, and +0.090 %/°C temperature coefficient. It regulates voltage across wide current and temperature ranges in high-reliability power supply reference circuits.
For engineers reviewing the 1N4116-1 datasheet, 1N4116-1 pinout, 1N4116-1 application, or 1N4116-1 equivalent, this page delivers verified electrical specs, military-grade qualification status, thermal derating behavior, noise density (1 µV/√Hz), and axial-leaded mechanical mounting details critical for aerospace, defense, and industrial analog design.
Technical Context
The 1N4116-1 operates as a precision voltage reference in reverse-biased breakdown mode, with regulation established at IZT = 250 mA. Its internal metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure, supporting JANS-level reliability requirements.
It exhibits low noise density (1 µV/√Hz), minimal capacitance (~16 pF), and a positive temperature coefficient (+0.090 %/°C), enabling stable reference performance in analog feedback loops and voltage-monitoring circuits where drift compensation is required.

FAQ
What is the Zener voltage tolerance for the 1N4116-1?
The 1N4116-1 has a nominal Zener voltage of 24.0 V with a standard tolerance of ±5%, as defined in the JEDEC registration and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with IZT = 250 mA.
Is the 1N4116-1 suitable for space applications?
Yes, the 1N4116-1 is qualified to JANS level per MIL-PRF-19500/435 and features inherent radiation hardness documented in Microsemi MicroNote 050. Its metallurgically bonded structure, hermetic DO-35 package, and operation up to +175 °C make it suitable for spacecraft voltage reference use when procured to JANS specification.
What is the maximum reverse leakage current for the 1N4116-1?
The maximum reverse leakage current (IR) for the 1N4116-1 is 0.01 µA measured at VR = 19.2 V (80% of VZ), as specified in the Electrical Characteristics table. This ultra-low leakage supports high-impedance bias networks and precision reference divider designs.
Does the 1N4116-1 have RoHS-compliant variants?
Yes - RoHS-compliant versions of the 1N4116-1 are available with the "e3" suffix (e.g., 1N4116-1e3), but only in commercial-grade configurations. MIL-qualified versions (JAN/JANTX/JANTXV/JANS) retain tin-lead plating per military specifications and are not RoHS compliant.
How does thermal derating apply to the 1N4116-1?
The 1N4116-1 linearly derates from 500 mW starting at 25 °C ambient, reaching zero dissipation at 175 °C, per Figure 2 in T4-LDS-0245-2. On a typical FR4 board with 1 oz copper, power must be reduced by 3.33 mW/°C above 25 °C to maintain safe junction temperature.
