Product details
Overview
JAN1N4117-1/TR from Microsemi is a 25 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JAN reliability level per MIL-PRF-19500/435, with ±5% Zener voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and 0.01 µA maximum reverse leakage at 19.0 V. It serves as a precision voltage reference in military-grade power supply regulation and analog signal conditioning circuits.
For engineers reviewing the JAN1N4117-1/TR datasheet, JAN1N4117-1/TR pinout, JAN1N4117-1/TR application, or JAN1N4117-1/TR equivalent, key selection criteria include its MIL-qualified JAN-level reliability, low noise density (1 µV/√Hz), temperature coefficient of +0.090 %/°C, hermetic glass package, and compatibility with manual or wave soldering per MIL-STD-750.
Technical Context
This device operates in reverse breakdown to maintain stable 25 V regulation across wide current (250 mA test point) and temperature (–65 °C to +175 °C) ranges. Its metallurgically bonded junction ensures low thermal resistance (250 °C/W junction-to-lead) and radiation hardness per Microsemi MicroNote 050.
The diode exhibits minimal capacitance (typical <2 pF at 0 V), low noise density (1 µV/√Hz), and non-ESD-sensitive behavior per MIL-STD-750 Method 1020 - critical for high-reliability analog front-ends and space-qualified instrumentation.

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 electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or repair | Select when automated assembly and board space constraints outweigh lead-forming flexibility |
| JANTXV1N4117-1 | Identical DO-35 package and 25 V rating, but qualified to JANTXV level with tighter screening and extended temp validation | Higher cost and longer lead time; justified only for flight-critical subsystems requiring enhanced burn-in and lot traceability | Select when system-level qualification mandates JANTXV-level screening beyond JAN requirements |
Compared with JAN1N4117-1/TR, the 1N4117US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-soldering ease, while JANTXV1N4117-1 adds screening rigor at higher cost - making JAN1N4117-1/TR the optimal balance of reliability, manufacturability, and cost for ground-based military electronics.

FAQ
What is the Zener voltage tolerance for JAN1N4117-1/TR?
The JAN1N4117-1/TR has a nominal Zener voltage of 25.0 V with a standard tolerance of ±5%, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This tolerance applies under thermal equilibrium conditions at 25 °C and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Is JAN1N4117-1/TR RoHS compliant?
No, JAN1N4117-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4117-1e3); JAN-level parts like JAN1N4117-1/TR use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS restrictions due to their military qualification and reliability requirements.
What is the maximum reverse leakage current for JAN1N4117-1/TR?
The maximum reverse leakage current (IR) for JAN1N4117-1/TR is 0.01 µA at a reverse voltage (VR) of 19.0 V, as confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports stable reference performance in high-impedance analog circuits.
Can JAN1N4117-1/TR be used in surface-mount designs?
No - JAN1N4117-1/TR uses an axial-leaded DO-35 (DO-204AH) glass package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4117US-1 in DO-213AA package, which shares identical electrical specifications but requires reflow-compatible layout and handling.
What is the thermal resistance junction-to-lead for JAN1N4117-1/TR?
The thermal resistance junction-to-lead (RθJL) for JAN1N4117-1/TR is 250 °C/W when measured with 3/8 inch (10 mm) lead length from the body, as stated in the Maximum Ratings table on page 1 of the T4-LDS-0245-2 datasheet - a key parameter for calculating junction temperature rise under 500 mW dissipation.
