Product details
Overview
JANTXV1N4117C-1/TR 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/TR datasheet, JANTXV1N4117C-1/TR pinout, JANTXV1N4117C-1/TR application, or JANTXV1N4117C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), low noise density (1 µV/√Hz), JANTXV qualification, thermal resistance (250 °C/W junction-to-lead), and DO-35 axial-leaded hermetic packaging.
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 temperature coefficient of +0.090 %/°C and dynamic impedance of 150 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current (1–40 mA) and temperature (−65 to +175 °C) ranges.
Designed for high-reliability mil-spec applications, JANTXV1N4117C-1/TR maintains ≤0.01 µA reverse leakage at 19.0 V and delivers minimal capacitance (<2 pF typical) per Figure 3, supporting low-noise analog references and stable feedback paths in regulated DC-DC converters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US-1 | Same 25 V ±2% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated pick-and-place and board space savings are prioritized over manual assembly flexibility |
| JAN1N4117C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening vs. JANTXV) | Lacks extended life test and burn-in required for mission-critical flight hardware | Select for cost-sensitive ground-test or non-flight subsystems where full JANTXV screening is not mandated |
Compared with JANTXV1N4117C-1/TR, 1N4117US-1 trades axial-leaded serviceability for SMT compatibility, while JAN1N4117C-1 reduces qualification rigor to lower cost-neither offers pin-compatible replacement without verifying system-level reliability requirements.

FAQ
What is the Zener voltage tolerance of JANTXV1N4117C-1/TR?
JANTXV1N4117C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual breakdown voltage falls within 24.5 V to 25.5 V when measured at the specified 250 mA test current and 25 °C ambient temperature, enabling tighter regulation than standard ±5% variants.
Is JANTXV1N4117C-1/TR suitable for high-temperature operation?
Yes, JANTXV1N4117C-1/TR is rated for junction temperatures from −65 to +175 °C and features a linear power derating curve that maintains 500 mW dissipation up to 50 °C lead temperature. Its metallurgical bond construction and hermetic DO-35 package ensure stable performance in extended thermal environments typical of avionics and downhole equipment.
Does JANTXV1N4117C-1/TR meet RoHS requirements?
No, JANTXV1N4117C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What does the "TR" suffix indicate in JANTXV1N4117C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. JANTXV1N4117C-1/TR is supplied in reels for SMT or axial insertion equipment, with quantities and reel specifications available upon request from Aetrix Electronics or Microchip/Microsemi factory.
How does JANTXV1N4117C-1/TR compare to commercial-grade 1N4117 diodes?
JANTXV1N4117C-1/TR undergoes rigorous MIL-PRF-19500/435 screening-including extended life testing, burn-in, and lot traceability-unlike commercial 1N4117 variants. It also features tighter tolerances (±2% vs. ±5%), guaranteed low noise (1 µV/√Hz), and higher temperature capability (−65 to +175 °C), making it suitable for mission-critical systems where failure is not an option.
