Product details
Overview
JANTX1N4117-1/TR from Microsemi is a 25 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level, with 1% Zener voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and 0.01 µA maximum reverse leakage at 19.0 V. It regulates voltage in precision reference and power supply feedback circuits across military avionics and space-grade instrumentation.
For engineers reviewing the JANTX1N4117-1/TR datasheet, JANTX1N4117-1/TR pinout, JANTX1N4117-1/TR application, or JANTX1N4117-1/TR equivalent, key selection criteria include its MIL-qualified reliability, low noise density (1 µV/√Hz), tight 1% voltage tolerance, and thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable Zener voltage under thermal cycling and radiation exposure, meeting JANTX-level screening for high-reliability systems.
It delivers 25 V regulation at 250 mA test current with ±1% tolerance, exhibits +0.090 %/°C temperature coefficient, and maintains ≤150 Ω dynamic impedance (ZZT) - critical for low-output-impedance references in closed-loop feedback paths.

| Dynamic Impedance ZZT | 150 Ω max at IZT = 250 mA - ensures low output impedance for ripple rejection in regulator feedback networks |
| Reverse Leakage IR | 0.01 µA max at VR = 19.0 V - guarantees negligible error current in high-impedance reference divider legs |
| Noise Density ND | 1 µV/√Hz typical - critical for low-noise analog references in precision ADC/DAC biasing |
| Temp Coefficient αVZ | +0.090 %/°C - allows predictable voltage shift over -65 to +175 °C operating range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Used where board space is constrained and reflow assembly is required | Select when automated SMT placement is mandatory and thermal mass constraints allow lower derated power |

FAQ
What is the Zener voltage tolerance of JANTX1N4117-1/TR?
JANTX1N4117-1/TR has a nominal Zener voltage of 25.0 V with ±1% tolerance, verified per MIL-PRF-19500/435 screening. This tight tolerance eliminates post-assembly calibration in many precision reference applications and ensures consistent performance across production lots without trimming components.
Does JANTX1N4117-1/TR meet military reliability standards?
Yes, JANTX1N4117-1/TR is fully qualified to MIL-PRF-19500/435 at the JANTX reliability level, including environmental stress screening, parametric testing, and lot acceptance procedures. Its metallurgical bond construction and hermetic DO-35 package support operation from -65 to +175 °C junction temperature in mission-critical systems.
What is the maximum reverse leakage current for JANTX1N4117-1/TR?
JANTX1N4117-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 19.0 V. This ultra-low leakage ensures minimal error contribution in high-impedance voltage divider networks and preserves accuracy in battery-powered or low-power sensor interface circuits.
How does the noise performance of JANTX1N4117-1/TR compare to standard Zeners?
JANTX1N4117-1/TR delivers 1 µV/√Hz typical noise density - significantly lower than generic commercial Zeners (often >10 µV/√Hz). This low-noise characteristic is achieved through optimized metallurgical bonding and process control, making JANTX1N4117-1/TR suitable for precision analog signal chains where reference noise directly impacts system resolution.
Is JANTX1N4117-1/TR RoHS compliant?
No, JANTX1N4117-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N4117-1e3), not for MIL-qualified JANTX-level parts. The JANTX1N4117-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
