Product details
Overview
JANTX1N4110C-1 from Microsemi is a 500 mW, 16 V Zener voltage regulator diode in DO-35 (DO-204AH) axial-glass package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and maximum reverse leakage of 0.05 µA at 12.2 V. It serves as a precision reference in military-grade power supply regulation and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4110C-1 datasheet, JANTX1N4110C-1 pinout, JANTX1N4110C-1 application, or JANTX1N4110C-1 equivalent, key selection criteria include its 16 V nominal Zener voltage, ±2% tolerance, 100 Ω dynamic impedance, -65°C to +175°C operating temperature range, and hermetically sealed glass package for high-reliability environments.
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current (250 mA IZT) and temperature (-65°C to +175°C) ranges. Its metallurgically bonded construction ensures low noise density (1 µV/√Hz typical at 16 V), minimal capacitance (~2.5 pF), and inherent radiation hardness per Microsemi MicroNote 050.
The JANTX1N4110C-1 exhibits a positive temperature coefficient of +0.085 %/°C and is rated for 0.5 W average power dissipation, derating linearly to zero at 175°C ambient. Cathode polarity is marked by a band; operation requires cathode-positive biasing relative to anode for Zener regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 16.0 V ±2% at 250 mA - provides precise reference voltage with tight tolerance for calibration-critical circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4110US-1 | Same 16 V ±2% Zener voltage, but in surface-mount DO-213AA package; no axial leads. | Used where PCB real estate is constrained and reflow assembly is required. | Select when transitioning from through-hole to SMT manufacturing; verify thermal pad layout per Microsemi AN-102. |
| JANS1N4110C-1 | Identical electrical specs, but qualified to JANS (highest MIL-PRF-19500/435 level) with extended screening. | Required for mission-critical spaceflight avionics with zero-failure tolerance. | Choose only when JANS-level radiation testing, burn-in, and lot traceability are mandated by program spec. |
Compared with JANTX1N4110C-1, the 1N4110US-1 offers identical regulation performance in a smaller footprint but lacks axial-lead mechanical robustness, while JANS1N4110C-1 adds cost and lead time for ultra-high-reliability screening not needed in most JANTX-tier programs.

FAQ
What is the Zener voltage tolerance of JANTX1N4110C-1?
JANTX1N4110C-1 has a nominal Zener voltage of 16.0 V with a ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25°C ambient, and remains stable across its full operating temperature range of -65°C to +175°C due to its metallurgically bonded construction.
Is JANTX1N4110C-1 suitable for high-reliability aerospace applications?
Yes, JANTX1N4110C-1 is qualified to the JANTX level per MIL-PRF-19500/435, including rigorous screening for vibration, thermal shock, and hermeticity. Its DO-35 glass package, internal metallurgical bond, and radiation-hardened design make it suitable for flight-critical subsystems such as satellite power converters and avionics reference supplies.
What is the maximum reverse leakage current for JANTX1N4110C-1?
The maximum reverse leakage current (IR) for JANTX1N4110C-1 is 0.05 µA measured at 12.2 V (76% of nominal VZ). This ultra-low leakage supports low-power standby modes in battery-operated defense electronics and ensures minimal loading on high-impedance reference nodes in precision analog circuits.
Does JANTX1N4110C-1 have a specified noise density?
Yes, JANTX1N4110C-1 has a typical noise density of 1 µV/√Hz at 25°C, measured using a 1 kHz–3 kHz bandpass filter at 250 mA Zener test current. This value is confirmed in Microsemi's T4-LDS-0245-2 datasheet and is critical for applications requiring low-noise voltage references, such as precision data acquisition front-ends.
What is the thermal resistance junction-to-lead for JANTX1N4110C-1?
JANTX1N4110C-1 has a thermal resistance junction-to-lead (RθJL) of 250°C/W when mounted with 3/8 inch (10 mm) lead length from body, per MIL-STD-750 Test Method 1020. This value enables accurate thermal modeling for power derating in conduction-cooled assemblies where lead heat sinking is the dominant path.
