Product details
Overview
JANTXV1N4103C-1/TR from Microsemi is a 500 mW, 9.1 V ±2% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability aerospace and defense voltage regulation. It delivers 250 mA test current, 200 Ω dynamic impedance at IZT, 0.5 µA max reverse leakage at 7.3 V, and +0.080 %/°C temperature coefficient.
For engineers reviewing the JANTXV1N4103C-1/TR datasheet, JANTXV1N4103C-1/TR pinout, JANTXV1N4103C-1/TR application, or JANTXV1N4103C-1/TR equivalent, key selection criteria include military-grade reliability qualification, tight 2% Zener voltage tolerance, low noise density (1 µV/√Hz), hermetic glass packaging, and thermal resistance of 250 °C/W junction-to-lead.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 9.1 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient (+0.080 %/°C) that stabilizes output under thermal drift. Its metallurgical bond construction ensures mechanical robustness and long-term parameter stability in harsh environments.
The DO-35 glass package provides hermetic sealing and ESD immunity per MIL-STD-750 Method 1020, while its 500 mW power rating is linearly derated from 500 mW at 25 °C ambient to zero at 175 °C - critical for sustained operation in high-temperature avionics and space-qualified systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.1 V ±2% at 250 mA - enables precise reference generation in analog power supplies and sensor biasing circuits. |
| Power Dissipation | 500 mW at TC = 25 °C - supports stable regulation across industrial temperature range with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 200 Ω at IZT = 250 mA - ensures minimal output voltage variation under load transients in feedback loops. |
| Reverse Leakage IR | ≤0.5 µA at VR = 7.3 V - guarantees low quiescent current in battery-backed or low-power monitoring circuits. |
| Noise Density ND | 1 µV/√Hz - critical for low-noise voltage references in precision instrumentation and ADC reference buffers. |
| Temp Coefficient αVZ | +0.080 %/°C - provides predictable, monotonic voltage drift over temperature for calibration-critical applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same 9.1 V, 2% tolerance, but in surface-mount DO-213AA package; no axial leads. | Used where PCB real estate is constrained and reflow assembly is required instead of through-hole mounting. | Select 1N4103US-1 only when board layout mandates SMT and thermal profile allows DO-213AA lead-free reflow. |
| JANTXV1N4103D-1/TR | Identical electrical specs but 1% Zener voltage tolerance (vs. 2% for JANTXV1N4103C-1/TR); same DO-35 package. | Required in metrology-grade calibration equipment where tighter initial accuracy is mandatory. | Choose JANTXV1N4103D-1/TR only when system-level accuracy budget demands ≤±1% VZ tolerance at 25 °C. |
Compared with JANTXV1N4103C-1/TR, the 1N4103US-1 offers identical regulation performance in a space-saving SMT form factor but sacrifices axial-lead mechanical robustness, while JANTXV1N4103D-1/TR trades 1% tighter tolerance for higher cost and potentially longer lead time - both require explicit validation of thermal and mechanical fit in final design.

FAQ
What is the Zener voltage tolerance of JANTXV1N4103C-1/TR?
JANTXV1N4103C-1/TR has a nominal Zener voltage of 9.1 V with a ±2% tolerance, meaning the actual measured VZ falls between 8.92 V and 9.28 V at 250 mA test current and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2 Rev. 1, and applies specifically to the "C" suffix variant of the JANTXV1N4103 series.
Is JANTXV1N4103C-1/TR RoHS compliant?
No, JANTXV1N4103C-1/TR is not RoHS compliant. Per the nomenclature table on page 2 of Microsemi T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance and is available only on commercial-grade versions; JANTXV-level parts like JANTXV1N4103C-1/TR retain standard tin-lead plating to meet MIL-PRF-19500/435 requirements.
What is the maximum reverse leakage current for JANTXV1N4103C-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4103C-1/TR is 0.5 µA at VR = 7.3 V and 25 °C, as specified in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2 Rev. 1. This value reflects the device's tight leakage control, critical for low-power standby modes in military electronics.
Does JANTXV1N4103C-1/TR have a positive or negative temperature coefficient?
JANTXV1N4103C-1/TR has a positive temperature coefficient of +0.080 %/°C, meaning its Zener voltage increases predictably with rising junction temperature. This value is explicitly listed in the Electrical Characteristics table for part number 1N4103-1 (the base commercial version), and applies identically to the JANTXV1N4103C-1/TR variant per Microsemi's qualification documentation.
What does the "TR" suffix mean in JANTXV1N4103C-1/TR?
Per the Mechanical and Packaging section on page 2 of Microsemi T4-LDS-0245-2 Rev. 1, the "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTXV1N4103C-1/TR is supplied in reel format optimized for high-volume military production lines requiring traceable, moisture-barrier packaging.
