Product details
Overview
JANTX1N4105C-1/TR from Microsemi is a 500 mW, 11.0 V ±2% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTX1N4105C-1/TR datasheet, JANTX1N4105C-1/TR pinout, JANTX1N4105C-1/TR application, or JANTX1N4105C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for radiation-hardened, low-noise, and thermally stable analog designs.
Technical Context
This device operates as a reverse-biased Zener regulator with nominal VZ = 11.0 V at IZT = 250 mA, exhibiting αVZ = +0.080 %/°C and ZZT = 200 Ω. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for hermetic axial-leaded mounting, it delivers low noise density (1 µV/√Hz typical at lower voltages), minimal capacitance (~40 pF), and ESD insensitivity per MIL-STD-750 Method 1020 - enabling use in analog front-ends and reference stages where signal integrity and long-term stability are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 11.0 V ±2% at 250 mA - enables precise mid-range voltage reference with tight initial tolerance. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports operation in high-temp avionics enclosures. |
| Dynamic Impedance ZZT | 200 Ω at 250 mA - ensures stable regulation under varying load current in feedback loops. |
| Temp. Coefficient αVZ | +0.080 %/°C - predictable positive drift allows compensation in multi-diode references. |
| Noise Density ND | 1 µV/√Hz (typical, <6.8 V range) - suitable for low-noise analog sensing and metrology references. |
| Reverse Leakage IR | 0.05 µA at 9.1 V - guarantees negligible current draw in standby bias networks. |
| Junction Temp. Range | -65 to +175 °C - validated for extended-range operation in space-grade and engine-control systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1/TR | Same VZ, same tolerance, but in surface-mount DO-213AA package; no axial leads. | Requires PCB redesign for SMT placement; eliminates through-hole assembly but sacrifices manual repairability. | Select when automated assembly and board space constraints outweigh field-serviceability needs. |
| JANTXV1N4105C-1/TR | Identical electrical specs, but qualified to higher JANTXV level with extended screening (e.g., burn-in, life test). | Required for mission-critical subsystems where failure probability must be <10−6/hour per MIL-HDBK-217F. | Select when program specification mandates JANTXV screening - not a drop-in replacement due to different qualification documentation. |
Compared with JANTX1N4105C-1/TR, the 1N4105US-1/TR offers footprint reduction at the cost of mechanical serviceability, while JANTXV1N4105C-1/TR provides statistically verified reliability for life-critical functions - neither is pin-compatible, and both require explicit design validation per application environment.

FAQ
What is the Zener voltage and tolerance of JANTX1N4105C-1/TR?
JANTX1N4105C-1/TR has a nominal Zener voltage of 11.0 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where "C" in the part number explicitly denotes 2% Zener voltage tolerance per the nomenclature guide.
Is JANTX1N4105C-1/TR RoHS compliant?
No, JANTX1N4105C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTX-level devices like JANTX1N4105C-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under defense procurement exceptions.
What is the maximum power dissipation and derating behavior of JANTX1N4105C-1/TR?
JANTX1N4105C-1/TR has a rated average power dissipation of 0.5 W at 25 °C, linearly derated to zero at 175 °C. Derating begins at 50 °C lead temperature per Note 2 on page 1; on a standard FR4 board, it starts at 25 °C ambient and follows the curve in Figure 2, ensuring safe operation up to 175 °C junction temperature.
Does JANTX1N4105C-1/TR have radiation hardness certification?
Yes, JANTX1N4105C-1/TR is inherently radiation hard as described in Microsemi MicroNote 050. While not individually tested per MIL-STD-883, its metallurgically bonded DO-35 construction and process heritage provide proven resistance to total ionizing dose (TID) and displacement damage - a key reason for its selection in satellite and nuclear instrumentation applications.
What is the noise performance of JANTX1N4105C-1/TR?
JANTX1N4105C-1/TR exhibits ≤1 µV/√Hz noise density at Zener voltages below 6.8 V, per the "Max Noise Density ND @ IZT" column on page 3 of the datasheet. At 11.0 V, noise increases slightly but remains among the lowest in the 1N41xx series, making it suitable for low-noise analog references where post-regulation filtering must be minimized.
