Product details
Overview
JANTX1N4104-1/TR from Microsemi is a 10.0 V, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level, with ±5% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and 0.5 µA maximum reverse leakage at 7.6 V. It serves as a precision voltage reference in military-grade power regulation and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4104-1/TR datasheet, JANTX1N4104-1/TR pinout, JANTX1N4104-1/TR application, or JANTX1N4104-1/TR equivalent, key selection criteria include its MIL-qualified reliability, low noise density (≤1 µV/√Hz below 6.8 V), thermal resistance of 250 °C/W (junction-to-lead), and compatibility with leaded through-hole assembly in high-reliability avionics and defense systems.
Technical Context
This Zener diode operates in reverse breakdown mode with cathode band indicating polarity, requiring banded end to be held positive relative to anode for regulation. Its metallurgical bond ensures stable junction characteristics across -65 °C to +175 °C operating range and radiation hardness per MicroNote 050.
It delivers regulated output at 10.0 V ±5% with 250 mA test current (IZT), exhibits 200 Ω dynamic impedance (ZZT), and maintains ≤0.5 µA reverse leakage (IR) at VR = 7.6 V - enabling stable reference performance under varying load and temperature conditions in analog feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.0 V ±5% at IZT = 250 mA - defines nominal regulation point with tight tolerance for precision reference use. |
| Power Dissipation | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - sets maximum continuous thermal load on PCB layout. |
| Dynamic Impedance | 200 Ω at IZT = 250 mA - determines output voltage variation under changing load current (ΔVZ ≈ ΔIZ × 200 Ω). |
| Reverse Leakage | ≤0.5 µA at VR = 7.6 V - ensures minimal error current in high-impedance reference networks. |
| Noise Density | ≤1 µV/√Hz (typical, <6.8 V range) - critical for low-noise analog front-ends and precision ADC references. |
| Temp Coefficient | +0.080 %/°C - quantifies drift rate; enables compensation design in wide-temperature environments. |
| Junction Temp Range | -65 °C to +175 °C - supports operation in extreme aerospace and downhole applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4104US | Same 10.0 V, ±5%, DO-213AA surface-mount package; no axial leads; RθJA = 400 °C/W vs. 250 °C/W (JANTX1N4104-1/TR). | Used where PCB space is constrained and reflow assembly required; unsuitable for through-hole prototyping or high-power dissipation without heatsinking. | Select 1N4104US only when surface-mount layout and thermal management allow higher junction rise. |
| JANTXV1N4104-1 | Identical electrical specs but qualified to JANTXV level (enhanced screening, tighter parametric limits, extended temperature testing). | Required for mission-critical flight hardware where failure modes demand stricter lot acceptance testing and burn-in. | Choose JANTXV1N4104-1 when program specifications mandate JANTXV-level reliability beyond standard JANTX. |
Compared with 1N4104US and JANTXV1N4104-1, JANTX1N4104-1/TR offers optimal balance of proven military reliability, axial-leaded ease-of-use, and thermal performance (RθJL = 250 °C/W) for through-hole power regulation in field-deployable systems.

FAQ
What is the Zener voltage tolerance and test condition for JANTX1N4104-1/TR?
JANTX1N4104-1/TR has a nominal Zener voltage of 10.0 V with ±5% tolerance, measured at IZT = 250 mA and TJ = 25 °C. This tolerance reflects the standard JEDEC specification for the 1N4104-1 series and applies to all JANTX-level variants unless otherwise screened. The device maintains regulation within this band across its full operating temperature range (-65 °C to +175 °C), with drift compensated by its +0.080 %/°C temperature coefficient.
Is JANTX1N4104-1/TR RoHS compliant?
No, JANTX1N4104-1/TR is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0245-2, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices. JANTX1N4104-1/TR uses traditional tin-lead plating per MIL-STD-750, method 2026, and retains lead content necessary for military soldering processes and reliability validation.
What is the maximum reverse leakage current for JANTX1N4104-1/TR and at what voltage is it specified?
JANTX1N4104-1/TR has a maximum reverse leakage current (IR) of 0.5 µA, specified at VR = 7.6 V - which is 76% of its nominal Zener voltage. This low leakage ensures minimal error current in high-impedance reference divider networks and supports accurate voltage sensing in low-power monitoring circuits across its full temperature range.
Can JANTX1N4104-1/TR be used in surface-mount applications?
No, JANTX1N4104-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is designed exclusively for through-hole mounting. For surface-mount equivalents, consider the 1N4104US in DO-213AA package - but note that it lacks JANTX qualification and has higher thermal resistance (RθJA = 400 °C/W). JANTX1N4104-1/TR requires axial insertion and wave or hand soldering.
What does the "TR" suffix indicate in JANTX1N4104-1/TR?
"TR" stands for Tape & Reel packaging per EIA-296 standard. JANTX1N4104-1/TR is supplied in industry-standard carrier tape and reel format for automated pick-and-place assembly. The base part number JANTX1N4104-1 remains electrically and mechanically identical; only the packaging differs. Quantity and reel size must be confirmed with factory prior to ordering.
