Product details
Overview
JANTX1N4106C-1/TR from Microsemi is a 12 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4106C-1/TR datasheet, JANTX1N4106C-1/TR pinout, JANTX1N4106C-1/TR application, or JANTX1N4106C-1/TR equivalent, key selection criteria include Zener voltage (12.0 V), test current (250 mA), dynamic impedance (200 Ω), temperature coefficient (+0.080 %/°C), and hermetic DO-35 packaging for stable operation across -65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 12.0 V at 250 mA test current, exhibiting a tight ±2% tolerance (denoted by "C" suffix) and low dynamic impedance of 200 Ω at IZT. Its metallurgical bond construction ensures stable regulation under thermal stress and radiation exposure.
The JANTX1N4106C-1/TR delivers low noise density (1 µV/√Hz typical at lower voltages) and minimal capacitance (≈2.5 pF per Figure 3), making it suitable for reference and biasing circuits where signal integrity and low parasitic effects are critical in analog and mixed-signal systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4106US-1 | Same electrical specs, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or repair | Select when automated placement and board space savings outweigh manual soldering needs |
| JANS1N4106C-1 | Identical electrical and mechanical specs, but qualified to JANS (highest MIL-PRF-19500 level) with full lot traceability | Required for nuclear-hardened systems and manned spacecraft where failure probability must be <1E-9/hour | Select only when JANS-level documentation, screening, and radiation testing are contractually mandated |
Compared with 1N4106US-1 and JANS1N4106C-1, the JANTX1N4106C-1/TR offers optimal balance of proven reliability, axial-lead serviceability, and cost-effective JANTX qualification for most defense electronics programs not requiring full JANS or SMT conversion.

FAQ
What is the Zener voltage and tolerance of JANTX1N4106C-1/TR?
JANTX1N4106C-1/TR has a nominal Zener voltage of 12.0 V at 250 mA test current with a ±2% tolerance, as confirmed by the "C" suffix in its nomenclature and verified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This tolerance ensures regulation within 11.76–12.24 V under specified conditions, critical for precision analog references in defense electronics where JANTX1N4106C-1/TR is deployed.
Is JANTX1N4106C-1/TR RoHS compliant?
No, JANTX1N4106C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTX-level devices like JANTX1N4106C-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and maintain legacy qualification integrity. This applies directly to JANTX1N4106C-1/TR's use in existing military platforms.
What is the maximum power dissipation and derating behavior of JANTX1N4106C-1/TR?
JANTX1N4106C-1/TR has a rated average power dissipation of 500 mW at 25 °C, linearly derating to zero at 175 °C per Figure 2. At lead temperature TL = 50 °C, derating begins, yielding ~430 mW usable power. This thermal profile is validated for JANTX1N4106C-1/TR in DO-35 package with 3/8″ lead length, supporting sustained operation in convection-cooled avionics enclosures where JANTX1N4106C-1/TR serves as primary voltage reference.
Does JANTX1N4106C-1/TR have radiation hardness?
Yes, JANTX1N4106C-1/TR exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide tolerance to total ionizing dose (TID) and single-event effects without additional shielding-making JANTX1N4106C-1/TR suitable for satellite telemetry and unmanned aerial vehicle (UAV) navigation systems where radiation-induced parameter shift must be avoided.
What does the "TR" suffix indicate in JANTX1N4106C-1/TR?
Per the Mechanical and Packaging section, the "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4106C-1/TR is supplied in this format for high-volume production of defense electronics, with reel quantities defined by factory specification-not a functional variant. All electrical and reliability characteristics remain identical to the bulk version of JANTX1N4106C-1/TR.
