Product details
Overview
JANTXV1N4117C-1 from Microsemi is a 25 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JANTXV1N4117C-1 datasheet, JANTXV1N4117C-1 pinout, JANTXV1N4117C-1 application, or JANTXV1N4117C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass packaging, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 25.0 V at 250 mA test current, exhibiting a dynamic impedance of 150 Ω and a temperature coefficient of +0.090 %/°C. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in reverse-biased mode with cathode band positive, it delivers regulated voltage across wide current ranges (IZK to IZM = 19.0 mA to 40 mA) while maintaining ≤0.01 µA reverse leakage at VR = 18.3 V and supporting noise-sensitive analog references via sub-1 µV/√Hz noise density.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117UR-1 | Same electrical specs, DO-213AA surface-mount package instead of DO-35 | Requires PCB rework for SMT assembly; no axial through-hole mounting option | Select when automated assembly and board space constraints outweigh manual repair needs |
| JANS1N4117C-1 | Identical electrical and mechanical specs, but qualified to JANS (highest MIL-PRF-19500 reliability level) | Required for mission-critical systems where burn-in, lot acceptance testing, and radiation assurance are mandated | Select only when JANS certification documentation and extended screening are contractually required |
Compared with JANTXV1N4117C-1, the 1N4117UR-1 offers identical regulation performance in a surface-mount form factor ideal for compact layouts, while JANS1N4117C-1 provides enhanced reliability screening for life-critical avionics-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance for JANTXV1N4117C-1?
JANTXV1N4117C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 25.0 V Zener voltage is guaranteed between 24.5 V and 25.5 V at IZT = 250 mA and TA = 25 °C. This tighter tolerance supports precision reference applications without external trimming.
Is JANTXV1N4117C-1 suitable for high-temperature operation?
Yes, JANTXV1N4117C-1 is rated for junction temperatures from –65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgically bonded glass construction and hermetic DO-35 package ensure parametric stability in extended-temperature aerospace and downhole applications.
Does JANTXV1N4117C-1 meet RoHS requirements?
No, JANTXV1N4117C-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4117C-1e3); military-grade variants like JANTXV1N4117C-1 retain tin-lead plating per MIL-STD-750 to ensure solderability and reliability in high-reliability assemblies.
What is the maximum reverse leakage current for JANTXV1N4117C-1?
JANTXV1N4117C-1 has a maximum reverse leakage current (IR) of 0.01 µA at VR = 18.3 V and TA = 25 °C. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision reference circuits where input currents must remain below 100 pA.
How does the noise performance of JANTXV1N4117C-1 compare to standard Zeners?
JANTXV1N4117C-1 delivers 1 µV/√Hz noise density at IZT = 250 mA - significantly lower than typical commercial Zeners (often >10 µV/√Hz). This low-noise characteristic stems from its metallurgical bond construction and is confirmed in Microsemi MicroNote 050, making JANTXV1N4117C-1 suitable for high-fidelity analog references.
