Product details
Overview
JANTX1N4103C-1/TR from Microsemi is a 500 mW, 9.1 V ±2% tolerance Zener diode in DO-35 glass axial package, qualified to JANTX reliability level per MIL-PRF-19500/435, used for precision voltage regulation in military-grade power supply reference and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4103C-1/TR datasheet, JANTX1N4103C-1/TR pinout, JANTX1N4103C-1/TR application, or JANTX1N4103C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.080 %/°C), and hermetic DO-35 packaging for high-reliability environments.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded junction construction, enabling stable regulation across -65 °C to +175 °C ambient range and low noise performance critical for precision analog systems. Its 200 Ω dynamic impedance at 250 mA test current ensures minimal output voltage variation under load shifts.
The JANTX qualification mandates rigorous screening including burn-in, temperature cycling, and parameter verification per MIL-PRF-19500/435, while the DO-35 package provides hermetic sealing and thermal resistance of 250 °C/W (junction-to-lead) for sustained 500 mW operation at controlled lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.1 V ±2% at 250 mA - defines precise regulation point with tight tolerance for reference stability |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous operation in compact layouts with linear derating above 50 °C |
| Dynamic Impedance ZZT | 200 Ω max at IZT = 250 mA - limits output voltage shift under varying load current |
| Noise Density | 1 µV/√Hz @ IZT = 250 mA - enables low-noise performance in sensitive analog references |
| Temp. Coefficient αVZ | +0.080 %/°C - quantifies voltage drift over temperature for system-level error budgeting |
| Reverse Leakage IR | 0.5 µA max @ VR = 7.0 V - ensures minimal parasitic current in high-impedance bias networks |
| Junction Temp. Range | -65 °C to +175 °C - supports operation in extreme environmental conditions without derating |

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 electrical specs but in surface-mount DO-213AA package; no axial leads | Used where PCB space constraints prohibit through-hole mounting | Select when automated SMT assembly is required and thermal path differs (RθJA = 400 °C/W vs. 300 °C/W) |
| JANTXV1N4103C-1 | Identical electrical and mechanical specs but qualified to JANTXV level with extended screening (e.g., 100% life test) | Required for mission-critical subsystems where failure probability must be <10−6/hour | Select when system safety integrity level (SIL) or MIL-HDBK-217F failure rate targets mandate JANTXV screening |
Compared with JANTX1N4103C-1/TR, the 1N4103US-1 offers identical regulation performance in a smaller footprint but requires re-optimization of thermal layout, while the JANTXV1N4103C-1 delivers statistically verified reliability for life-critical functions without changing circuit design or board layout.

FAQ
What is the Zener voltage tolerance for JANTX1N4103C-1/TR?
The "C" suffix in JANTX1N4103C-1/TR denotes ±2% Zener voltage tolerance at 250 mA test current, tighter than the standard ±5% (blank suffix) and enabling higher accuracy in regulated reference designs without external trimming.
Is JANTX1N4103C-1/TR RoHS compliant?
No - JANTX1N4103C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTX-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum Zener current IZM for JANTX1N4103C-1/TR?
The maximum Zener current IZM for JANTX1N4103C-1/TR is 40 mA, derived from its 500 mW power rating and 9.1 V nominal Zener voltage (IZM = PM(AV)/VZ ≈ 55 mA, derated to 40 mA per absolute maximum ratings table on page 3).
How does the temperature coefficient affect JANTX1N4103C-1/TR in circuit design?
The +0.080 %/°C temperature coefficient of JANTX1N4103C-1/TR means its Zener voltage increases by approximately 7.3 mV per °C rise - a critical factor when designing reference circuits for wide-temperature-range applications like avionics or ground vehicles.
What packaging option does the "TR" suffix indicate for JANTX1N4103C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly; the base part JANTX1N4103C-1 is supplied in bulk or ammo pack, while JANTX1N4103C-1/TR is optimized for high-volume SMT production lines.
