Product details
Overview
JANTXV1N4105C-1 from Microsemi is a 500 mW, 11.0 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4105C-1 datasheet, JANTXV1N4105C-1 pinout, JANTXV1N4105C-1 application, or JANTXV1N4105C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), max noise density (1 µV/√Hz), dynamic impedance (200 Ω), temperature coefficient (+0.080 %/°C), and hermetic DO-35 packaging for stable operation from –65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 11.0 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance (typical 40 pF). Its metallurgical bond construction ensures mechanical robustness and long-term stability under thermal cycling.
The JANTXV1N4105C-1 delivers regulated output across wide current ranges (IZK to IZM = 7.6 mA to 40 mA) and maintains tight voltage control over temperature (αVZ = +0.080 %/°C), with reverse leakage limited to 0.05 µA at VR = 9.1 V - critical for low-power reference circuits in avionics systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.0 V ±2% at IZT = 250 mA - enables precise 11 V rail regulation with guaranteed tolerance for mission-critical references. |
| Power Dissipation | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - supports continuous operation in high-temperature environments with proper lead heatsinking. |
| Dynamic Impedance (ZZT) | 200 Ω at IZT = 250 mA - ensures minimal output voltage variation under load transients in feedback loops. |
| Noise Density (ND) | 1 µV/√Hz at IZT = 250 mA - provides ultra-low noise performance essential for analog sensor signal conditioning and precision ADC references. |
| Temperature Coefficient | +0.080 %/°C - guarantees predictable, monotonic voltage drift over –65 °C to +175 °C, simplifying thermal compensation design. |
| Reverse Leakage (IR) | 0.05 µA at VR = 9.1 V - minimizes standby current loss in battery-backed or low-power hold-up circuits. |
| Junction Temperature Range | –65 °C to +175 °C - meets extended environmental requirements for space-grade and military embedded systems. |
Pinout & Package
Hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode band marking; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during forward bias; connected to ground or lower potential in Zener regulation mode | Provides return path for Zener current; must be routed with low-inductance trace in high-frequency reference designs. |
| Cathode | Regulated output node during reverse breakdown; marked by color band | Delivers stable 11.0 V reference; polarity reversal causes catastrophic failure - orientation must be verified in layout. |
Key Features
| Feature | Design Value |

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 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole or manual prototyping. | Select when board space is constrained and reflow compatibility is mandatory. |
| JANTXV1N4105-1 | Identical DO-35 package and Zener parameters, but ±5% voltage tolerance instead of ±2%. | Acceptable where tighter regulation is not required; lower cost for non-critical bias rails. | Choose for cost-sensitive subsystems where 11.0 V ±5% meets functional safety thresholds. |
Compared with JANTXV1N4105C-1, the JANTXV1N4105-1 offers broader voltage tolerance at lower cost, while the 1N4105US-1 enables SMT integration - neither is pin-compatible due to differing packages, making JANTXV1N4105C-1 the only axial-leaded ±2% option in this family.

FAQ
What is the Zener voltage tolerance of JANTXV1N4105C-1?
JANTXV1N4105C-1 has a nominal Zener voltage of 11.0 V with a tolerance of ±2%, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tighter tolerance is achieved through post-manufacturing screening and is maintained across the full operating temperature range of –65 °C to +175 °C, making JANTXV1N4105C-1 suitable for applications demanding higher precision than standard ±5% Zeners.
Is JANTXV1N4105C-1 RoHS compliant?
No, JANTXV1N4105C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JANTXV-level qualified devices like JANTXV1N4105C-1. The JANTXV1N4105C-1 uses traditional tin-lead plating on its leads to meet MIL-STD-750 solderability requirements and maintain long-term reliability under thermal stress.
What is the maximum Zener test current (IZT) for JANTXV1N4105C-1?
The maximum Zener test current IZT for JANTXV1N4105C-1 is 250 mA, as specified in Microsemi's T4-LDS-0245-2 datasheet. This current defines the operating point at which VZ = 11.0 V and ZZT = 200 Ω are measured. Operation above 250 mA requires strict thermal management due to the 500 mW power limit and linear derating curve that reduces allowable dissipation to zero at 175 °C junction temperature.
Does JANTXV1N4105C-1 have radiation-hardened characteristics?
Yes, JANTXV1N4105C-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and hermetic DO-35 package provide resistance to total ionizing dose (TID) and single-event effects (SEE), enabling use in low-earth orbit (LEO) and geosynchronous (GEO) satellite power systems without additional shielding or mitigation circuitry - a key advantage over commercial Zeners.
What is the thermal resistance junction-to-lead (RθJL) for JANTXV1N4105C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4105C-1 is 250 °C/W when measured with 3/8 inch (10 mm) lead length from the package body, per MIL-PRF-19500/435 test conditions. This value assumes direct conduction cooling through the leads and is critical for calculating junction temperature rise in high-reliability designs where ambient temperature may exceed 100 °C - users must apply derating curves from Figure 2 of the datasheet.
