Product details
Overview
JANS1N4117-1/TR from Microsemi is a 25 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435, with ±1% voltage tolerance, 150 Ω dynamic impedance at 250 mA, and 0.01 µA reverse leakage at 19.0 V. It serves as a precision voltage reference in radiation-hardened military power regulation circuits.
For engineers reviewing the JANS1N4117-1/TR datasheet, JANS1N4117-1/TR pinout, JANS1N4117-1/TR application, or JANS1N4117-1/TR equivalent, key selection criteria include its JANS-level qualification, 25 V nominal Zener voltage with 1% tolerance, low noise density (1 µV/√Hz), radiation hardness, and DO-35 axial-leaded hermetic packaging for high-reliability analog reference design.
Technical Context
This device operates in reverse breakdown with cathode-banded polarity, requiring biasing with the banded end positive relative to the anode. Its metallurgical bond ensures stable Zener voltage under thermal cycling and mechanical stress, critical for aerospace and defense systems where long-term parametric drift must be minimized.
The JANS1N4117-1/TR exhibits a +0.090 %/°C temperature coefficient and maintains ≤150 Ω dynamic impedance across its rated 250 mA test current, enabling predictable regulation over wide current and temperature ranges without external compensation circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4117-1 | Same 25 V, 1% tolerance, DO-35 package, but qualified only to JANTXV level (not JANS); higher allowable failure rate per MIL-PRF-19500/435 | Lacks full JANS screening for radiation hardness and extended life testing; unsuitable for spaceflight or nuclear environments | Select when cost sensitivity outweighs requirement for full JANS assurance in ground-based military systems |
| 1N4117US-1 | Same electrical specs, but in surface-mount DO-213AA package; no axial leads; RoHS-compliant only | Requires PCB rework for SMT assembly; not interchangeable in through-hole designs; lacks JANS qualification entirely | Select only for new SMT designs where board space is constrained and JANS is not mandated |

FAQ
What is the Zener voltage tolerance of JANS1N4117-1/TR?
The JANS1N4117-1/TR has a nominal Zener voltage of 25.0 V with a ±1% tolerance, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tight tolerance is achieved via post-process binning and is guaranteed under MIL-PRF-19500/435 JANS-level screening. The JANS1N4117-1/TR maintains this specification across its full operating temperature range of –65 to +175 °C.
Is JANS1N4117-1/TR radiation hardened?
Yes, the JANS1N4117-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 packaging provide immunity to total ionizing dose (TID) effects up to levels required for low-earth orbit satellite missions. This radiation hardness is a core design feature of the JANS1N4117-1/TR and is validated as part of its JANS qualification.
What is the maximum reverse leakage current for JANS1N4117-1/TR?
The maximum reverse leakage current (IR) for JANS1N4117-1/TR is 0.01 µA at 19.0 V, per the Electrical Characteristics table on page 3. This ultra-low leakage supports low-power reference designs and ensures minimal current draw in standby modes. The JANS1N4117-1/TR achieves this performance due to its high-purity silicon and controlled metallurgical bonding process.
Does JANS1N4117-1/TR have RoHS compliance?
No, the JANS1N4117-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANS1N4117-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements and ensure long-term reliability in harsh environments.
What package type does JANS1N4117-1/TR use?
The JANS1N4117-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Its dimensions are defined in the Package Dimensions table on page 5, with body diameter 1.42–2.29 mm and overall length 3.56–5.08 mm. The "TR" suffix indicates tape-and-reel packaging per EIA-296, confirming the JANS1N4117-1/TR is supplied in automated assembly-ready format.
