Product details
Overview
JANTX1N4103D-1 from Microsemi is a 500 mW, 9.1 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4103D-1 datasheet, JANTX1N4103D-1 pinout, JANTX1N4103D-1 application, or JANTX1N4103D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - all critical for precision reference and ruggedized analog circuit design.
Technical Context
This device operates as a two-terminal reverse-biased voltage reference with a nominal Zener voltage of 9.1 V at 250 mA test current, exhibiting +0.080 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation across –65 °C to +175 °C junction temperature range, it delivers regulated output with ≤0.5 µA reverse leakage at VR = 7.0 V and maintains low noise density (1 µV/√Hz typical), making it suitable for low-noise analog references where stability and ESD immunity (MIL-STD-750 Method 1020) are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.1 V ±1% at IZT = 250 mA - enables precise voltage clamping or reference generation within tight tolerance bands. |
| Power Dissipation | 500 mW at TC = 25 °C - supports continuous regulation in compact through-hole designs with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 200 Ω at IZT = 250 mA - ensures minimal output voltage variation under load current changes in feedback loops. |
| Temp. Coefficient αVZ | +0.080 %/°C - provides predictable, positive drift behavior for temperature-compensated reference circuits. |
| Noise Density ND | 1 µV/√Hz - delivers ultra-low broadband noise essential for high-fidelity analog signal conditioning and precision ADC references. |
| Reverse Leakage IR | ≤0.5 µA at VR = 7.0 V - guarantees minimal standby current in battery-backed or low-power monitoring circuits. |
| Junction Temp. Range | –65 °C to +175 °C - validated for extreme-environment deployment in avionics, space-grade power systems, and downhole electronics. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode indicated by band; operated with banded end positive for Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; defines return path for Zener current. |

Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for aerospace and defense programs requiring traceable lot data and extended lifetime testing. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock, ensuring long-term parameter stability in cyclic environments. |
| 1% Zener voltage tolerance (D suffix) | Reduces need for external trimming in precision reference designs, lowering BOM count and calibration labor. |
| Low capacitance (typ. <2 pF) | Minimizes high-frequency coupling in RF-adjacent analog stages and preserves signal integrity in mixed-signal PCBs. |
| ESD immunity per MIL-STD-750 Method 1020 | Withstands human-body-model discharges without parameter shift - critical for handling during manual assembly or field repair. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow soldering is preferred over through-hole assembly. | Select when transitioning from through-hole to SMT production or when minimizing board footprint is mandatory. |
| JAN1N4103D-1 | Identical electrical and mechanical specs, but qualified only to JAN level (lower screening than JANTX). | Suitable for non-critical subsystems where full JANTX environmental testing is not mandated. | Choose for cost-sensitive programs where MIL-PRF-19500/435 Class B (JAN) suffices and JANTX-level burn-in is unnecessary. |
Compared with JANTX1N4103D-1, the 1N4103US-1 offers identical regulation performance in a smaller footprint but requires SMT process validation, while JAN1N4103D-1 reduces procurement cost and lead time at the expense of JANTX-level thermal and vibration screening rigor.

FAQ
What is the Zener voltage tolerance of JANTX1N4103D-1?
JANTX1N4103D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This means its nominal 9.1 V Zener voltage is guaranteed between 9.009 V and 9.191 V at 250 mA test current and 25 °C, supporting high-accuracy reference designs without post-manufacture trimming.
Is JANTX1N4103D-1 RoHS compliant?
No, JANTX1N4103D-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants (blank reliability level), not for JANTX-qualified parts which retain tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum operating temperature for JANTX1N4103D-1?
JANTX1N4103D-1 supports a junction and storage temperature range of –65 °C to +175 °C. Its power dissipation must be linearly derated from 500 mW starting at 50 °C lead temperature, reaching zero at 175 °C - a key constraint for high-temperature enclosure or engine-mounted applications.
How does the temperature coefficient affect JANTX1N4103D-1 in precision circuits?
JANTX1N4103D-1 has a temperature coefficient of +0.080 %/°C, meaning its Zener voltage increases by approximately 7.3 mV per °C rise above 25 °C. In precision references, this predictable positive drift can be compensated using complementary TC components or calibrated lookup tables in firmware.
Can JANTX1N4103D-1 replace JANTX1N4102D-1 in a design?
No - JANTX1N4103D-1 (9.1 V) and JANTX1N4102D-1 (8.7 V) have different nominal Zener voltages and distinct temperature coefficients (+0.080 %/°C vs. +0.075 %/°C). Substitution would alter regulation setpoints and thermal behavior, requiring full circuit revalidation including loop stability and noise margin analysis for JANTX1N4103D-1.
