Product details
Overview
JANTX1N4105C-1 from Microsemi is a 500 mW, 11.0 V Zener diode in DO-35 glass package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance at 25 °C - used for precision voltage regulation in military-grade power supply references and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4105C-1 datasheet, JANTX1N4105C-1 pinout, JANTX1N4105C-1 application, or JANTX1N4105C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 μV/√Hz), radiation hardness, hermetic glass packaging, and MIL-qualified thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 11.0 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient of +0.080 %/°C and dynamic impedance of 200 Ω measured at 10% rms AC modulation superimposed on IZT. Its metallurgically bonded construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTX1N4105C-1 meets MIL-PRF-19500/435 requirements for JANTX-level screening, including extended temperature operation (–65 to +175 °C), hermetic glass sealing, and ESD immunity per MIL-STD-750 Method 1020 - enabling use in avionics, space-qualified instrumentation, and hardened industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.0 V ±2% at 250 mA - defines precise regulation point for reference design with tight tolerance critical for calibration-grade circuits. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - supports stable operation in conduction-cooled military enclosures without forced airflow. |
| Dynamic Impedance (ZZT) | 200 Ω at 250 mA - limits output voltage variation under load transients, ensuring <±11 mV shift per 2.2 mA current change. |
| Noise Density (ND) | 1 μV/√Hz at 25 °C - enables low-noise analog references in precision ADC front-ends and sensor excitation circuits. |
| Reverse Leakage (IR) | 0.05 µA at 8.5 V - guarantees minimal parasitic current draw in high-impedance bias networks and standby power paths. |
| Temp Coefficient (αVZ) | +0.080 %/°C - predictable drift behavior allows accurate compensation in temperature-stable reference designs. |
| Junction Temp Range | –65 to +175 °C - validated for operation in extreme environments including missile guidance electronics and downhole drilling tools. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where PCB space constraints prohibit through-hole mounting; lacks JANTX screening. | Select for commercial SMT designs needing identical VZ but not requiring MIL qualification. |
| JANTXV1N4105C-1 | Identical VZ, tolerance, and package; qualified to higher JANTXV screening level with additional environmental tests. | Required for programs specifying JANTXV-level reliability (e.g., DoD prime contracts). | Choose when system-level qualification mandates enhanced screening beyond JANTX. |
Compared with JANTX1N4105C-1, the 1N4105US-1 offers footprint compatibility for SMT assembly but forfeits military screening, while JANTXV1N4105C-1 delivers identical performance with stricter reliability validation - making the original optimal for cost-sensitive JANTX-tier programs.

FAQ
What is the Zener voltage tolerance of JANTX1N4105C-1?
JANTX1N4105C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its nominal 11.0 V Zener voltage falls within 10.78 V to 11.22 V at 250 mA test current and 25 °C ambient - critical for applications demanding tighter regulation than standard ±5% devices.
Does JANTX1N4105C-1 meet MIL-PRF-19500/435 requirements?
Yes, JANTX1N4105C-1 is fully qualified to MIL-PRF-19500/435 at the JANTX reliability level, including screening for thermal shock, vibration, and burn-in. Documentation confirms compliance with all applicable tests in the specification, making it suitable for use in Department of Defense and NASA programs requiring certified high-reliability components.
What is the maximum operating temperature for JANTX1N4105C-1?
JANTX1N4105C-1 supports a junction temperature range of –65 to +175 °C. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C, enabling reliable operation in extreme environments such as engine-mounted avionics or downhole oilfield tools - provided thermal management maintains junction temperature within this limit.
Is JANTX1N4105C-1 RoHS compliant?
No, JANTX1N4105C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N4105C-1e3), not for JAN/JANTX/JANTXV/JANS military-qualified parts, which retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What package type does JANTX1N4105C-1 use?
JANTX1N4105C-1 uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. It features a banded cathode end, tin-lead terminal plating, and mechanical dimensions conforming to JEDEC standards - with body diameter 1.42–2.29 mm and lead length 25.4–38.1 mm.
