For engineers reviewing the JANTX1N4117C-1/TR datasheet, JANTX1N4117C-1/TR pinout, JANTX1N4117C-1/TR application, or JANTX1N4117C-1/TR equivalent, key selection factors include its 25 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA max reverse leakage at 19 V, and radiation-hardened hermetic DO-35 construction.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 25.0 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.090 %/°C and noise density of 1 µV/√Hz. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and mechanical stress.
The JANTX1N4117C-1/TR is rated for 500 mW average power dissipation at TL = 25 °C, with linear derating to zero at 175 °C junction temperature and a thermal resistance of 250 °C/W (junction-to-lead) when mounted with 10 mm lead length. It maintains ≤0.01 µA reverse current at VR = 19.0 V.

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 Zener voltage and ±2% tolerance, but in surface-mount DO-213AA package | Requires PCB re-layout for SMT assembly; lacks axial-lead mounting flexibility | Select when automated assembly and board space constraints outweigh need for through-hole serviceability |
| JAN1N4117C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN (not JANTX) reliability level | Not approved for programs requiring MIL-PRF-19500/435 JANTX screening (e.g., DoD contracts) | Select only for non-military commercial applications where full JANTX testing is not mandated |
Compared with JANTX1N4117C-1/TR, the 1N4117US-1 offers identical regulation performance in a compact SMT form factor, while the JAN1N4117C-1 provides cost savings where JANTX-level screening is unnecessary - both require verification of thermal management and layout compatibility.

FAQ
What is the Zener voltage tolerance for JANTX1N4117C-1/TR?
The JANTX1N4117C-1/TR has a nominal Zener voltage of 25.0 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient temperature, and applies across the full military temperature range when derated per the power curve.
Is JANTX1N4117C-1/TR RoHS compliant?
No, JANTX1N4117C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4117C-1e3); the JANTX prefix denotes a military-qualified part with tin-lead plating per MIL-STD-750, which is exempt from RoHS requirements under EU Directive 2011/65/EU Annex III.
What does the "TR" suffix mean in JANTX1N4117C-1/TR?
The "TR" suffix in JANTX1N4117C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This version contains the same electrical and reliability specifications as the bulk-packaged JANTX1N4117C-1, with no functional or performance differences.
How is the cathode identified on JANTX1N4117C-1/TR?
The cathode of JANTX1N4117C-1/TR is marked by a distinct color band on the glass body of the DO-35 package. For proper Zener operation, the banded end must be connected to the higher-potential node (e.g., unregulated input), while the unbanded end (anode) connects to ground or the regulated reference point.
What is the maximum reverse leakage current for JANTX1N4117C-1/TR?
JANTX1N4117C-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at VR = 19.0 V, as specified in Microsemi's T4-LDS-0245-2 datasheet. This ultra-low leakage supports low-quiescent-current designs and ensures minimal loading on high-impedance reference nodes.
