Product details
Overview
JANTX1N4106D-1/TR from Microsemi is a 12 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4106D-1/TR datasheet, JANTX1N4106D-1/TR pinout, JANTX1N4106D-1/TR application, or JANTX1N4106D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision biasing, reference, and overvoltage protection design.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 12.0 V at 250 mA test current (IZT), exhibiting +0.080 %/°C temperature coefficient and 200 Ω maximum dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling.
Designed for hermetic axial-leaded mounting, JANTX1N4106D-1/TR maintains ≤0.05 µA reverse leakage (IR) at 9.2 V (VR), supports 9.2 mA maximum Zener current (IZM), and delivers low noise density (ND) of 1 µV/√Hz - optimized for analog reference and low-noise instrumentation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.0 V ±1% at 250 mA - enables precise voltage reference within tight tolerance for calibration-critical systems. |
| Power Dissipation | 500 mW at 25 °C - supports stable regulation in compact through-hole designs without forced cooling. |
| Dynamic Impedance | 200 Ω max at IZT - ensures minimal output voltage variation under load current changes. |
| Temp. Coefficient | +0.080 %/°C - provides predictable, monotonic VZ drift across -65 to +175 °C operating range. |
| Noise Density | 1 µV/√Hz - suitable for low-noise analog references where spectral purity affects measurement accuracy. |
| Reverse Leakage | ≤0.05 µA at 9.2 V - guarantees negligible current draw in standby or high-impedance bias networks. |
| Junction Temp. | -65 to +175 °C - validated for extreme-environment operation in avionics and space-grade electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; operated with banded end positive for Zener regulation. Hermetically sealed, tin-lead plated leads, ~0.2 g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point in regulation loop; defines return path for Zener current. |
| Cathode | Regulated output node | Banded end; supplies stable 12 V reference when reverse-biased; must be held at higher potential than anode. |
Key Features

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% Zener voltage but in DO-213AA surface-mount package; no JANTX qualification. | Used in space-constrained PCBs where axial leads are impractical; lacks military screening and extended temperature validation. | Select when board area is critical and MIL-spec is not required. |
| JANTXV1N4106D-1 | Identical electrical specs but qualified to JANTXV level (enhanced screening, tighter parametric limits, 100% lot testing). | Required for Class H/V avionics where failure modes demand higher confidence in early-life reliability. | Select when program mandates JANTXV-level assurance beyond JANTX baseline. |
Compared with JANTX1N4106D-1/TR, 1N4106US-1 trades military qualification for SMT compatibility, while JANTXV1N4106D-1 adds process controls and test coverage for mission-critical deployment - enabling selection based on reliability tier and form factor requirements.

FAQ
What is the Zener voltage tolerance of JANTX1N4106D-1/TR?
JANTX1N4106D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where VZ = 12.0 V at IZT = 250 mA with 1% tolerance specified for the 1N4106-1 series.
Is JANTX1N4106D-1/TR RoHS compliant?
No, JANTX1N4106D-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e3 suffix) are available only for commercial-grade parts; JANTX-level devices use traditional tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS restrictions.
What is the maximum Zener current (IZM) for JANTX1N4106D-1/TR?
The maximum Zener current (IZM) for JANTX1N4106D-1/TR is 9.2 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 under the "MAXIMUM ZENER CURRENT IZM" column for the 1N4106-1 entry.
Does JANTX1N4106D-1/TR have radiation hardness certification?
Yes, JANTX1N4106D-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. The metallurgically bonded glass construction and DO-35 package provide natural resistance to total ionizing dose (TID) effects, supporting use in low-earth orbit and tactical radiation environments.
What is the thermal resistance junction-to-lead (RθJL) for JANTX1N4106D-1/TR?
The thermal resistance junction-to-lead (RθJL) for JANTX1N4106D-1/TR is 250 °C/W, measured at 3/8 inch (10 mm) lead length from body, per the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1.
