Product details
Overview
JANTX1N4106D-1 from Microsemi is a 12 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX reliability level per MIL-PRF-19500/435, used for precision voltage regulation in military and aerospace power supply reference circuits.
For engineers reviewing the JANTX1N4106D-1 datasheet, JANTX1N4106D-1 pinout, JANTX1N4106D-1 application, or JANTX1N4106D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), dynamic impedance (200 Ω @ 250 mA), temperature coefficient (+0.080 %/°C), noise density (1 µV/√Hz), and hermetic DO-35 packaging for high-reliability environments.
Technical Context
This device operates as a two-terminal shunt voltage regulator with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. It maintains stable 12.0 V regulation across 250 mA test current and supports full-rated power up to +50 °C before linear derating to zero at +175 °C.
Its metallurgical bond construction ensures low leakage (≤0.05 µA @ 10.0 V), minimal capacitance (~4 pF typical), and inherent radiation hardness per Microsemi MicroNote 050 - critical for space-grade analog references and hardened instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.0 V ±1% @ 250 mA - enables precise 12 V reference generation with tight tolerance for calibration-critical systems. |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous regulation in compact axial-leaded layouts without forced cooling. |
| Dynamic Impedance ZZT | 200 Ω @ 250 mA - limits output voltage variation under load transients, improving regulation stability. |
| Temp Coefficient αVZ | +0.080 %/°C - predictable positive drift allows accurate thermal compensation in wide-temperature-range designs. |
| Noise Density ND | 1 µV/√Hz @ 250 mA - ultra-low broadband noise suitable for low-noise analog references and sensor excitation. |
| Reverse Leakage IR | ≤0.05 µA @ 10.0 V - ensures minimal standby current in battery-backed or low-power monitoring circuits. |
| Junction Temp Range | –65 °C to +175 °C - validated for extreme-environment operation in avionics, downhole tools, and missile guidance. |
Pinout & Package

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 12 V, 1% spec but in surface-mount DO-213AA package; no axial leads. | Used where PCB real estate is constrained and reflow assembly required. | Select when transitioning from through-hole to SMT while retaining identical electrical behavior. |
| JANTXV1N4106D-1 | Identical electrical specs but qualified to higher JANTXV level (enhanced screening, extended temp testing). | Required for Class S or Class H spaceflight hardware per NASA EEE-INST-002. | Select when program-level reliability requirements exceed JANTX baseline, especially for launch-critical subsystems. |
Compared with JANTX1N4106D-1, the 1N4106US-1 offers identical regulation performance in a smaller footprint but requires SMT process adaptation, while JANTXV1N4106D-1 delivers verified operation under more severe environmental stress without changing circuit design or layout.

FAQ
What is the Zener voltage and tolerance of JANTX1N4106D-1?
JANTX1N4106D-1 has a nominal Zener voltage of 12.0 V with ±1% tolerance, measured at 250 mA test current and 25 °C ambient. This tight tolerance is achieved via post-process binning and is guaranteed under MIL-PRF-19500/435 JANTX screening, making JANTX1N4106D-1 suitable for calibration-grade references where absolute accuracy matters.
What does the "D" suffix mean in JANTX1N4106D-1?
The "D" suffix in JANTX1N4106D-1 indicates 1% Zener voltage tolerance per the Microsemi part nomenclature guide. In the full designation, "JAN"/"JANTX" denotes reliability level, "1N4106" is the base JEDEC type, "D" specifies tolerance, and "-1" confirms metallurgically bonded construction - all confirmed in T4-LDS-0245-2 Rev. 1.
Is JANTX1N4106D-1 RoHS compliant?
No, JANTX1N4106D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants. JANTX1N4106D-1 retains traditional tin-lead plating to meet MIL-STD-750 solderability requirements and ensure compatibility with legacy defense manufacturing processes.
What is the maximum operating temperature for JANTX1N4106D-1?
JANTX1N4106D-1 is rated for junction and storage temperatures from –65 °C to +175 °C. Its power dissipation linearly derates from 500 mW at +25 °C to zero at +175 °C, and it remains fully functional at +175 °C junction temperature - a key specification validated for downhole and propulsion-system applications.
How is polarity marked on JANTX1N4106D-1?
JANTX1N4106D-1 uses a single black band to mark the cathode terminal, located at the banded end of the DO-35 glass body. The diode must be reverse-biased - i.e., the banded (cathode) end held positive relative to the unbanded (anode) end - to operate in Zener breakdown and deliver 12.0 V regulation. This marking is consistent across all 1N4099–1N4135-1 series devices.
