Product details
Overview
JANTX1N4117-1 from Microsemi is a 25 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level, with ±5% voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and 0.01 µA maximum reverse leakage at 19.0 V, used for precision voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4117-1 datasheet, JANTX1N4117-1 pinout, JANTX1N4117-1 application, or JANTX1N4117-1 equivalent, key selection criteria include Zener voltage stability over temperature (±0.09%/°C), low noise density (1 µV/√Hz), hermetic DO-35 packaging, and military-grade reliability qualification.
Technical Context
This device operates as a two-terminal voltage reference in reverse-bias breakdown mode, with Zener voltage specified at 250 mA test current (IZT) and characterized by tight thermal coefficient (αVZ = +0.090%/°C) and low dynamic impedance (ZZT = 150 Ω). Its metallurgical bond construction ensures stable long-term voltage regulation under thermal cycling.
The JANTX1N4117-1 exhibits minimal capacitance (typical <2 pF at 0 V), low noise density (1 µV/√Hz), and is rated for junction temperatures from –65 °C to +175 °C - enabling use in high-reliability analog signal conditioning and power supply feedback paths where stability across extreme environments is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 25.0 V at 250 mA - defines precise regulation point for feedback loops in regulated DC supplies. |
| Power Dissipation | 500 mW at 25 °C - supports stable operation in compact through-hole designs with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 150 Ω at IZT = 250 mA - ensures minimal output voltage variation under load current changes. |
| Reverse Leakage IR | 0.01 µA at VR = 19.0 V - guarantees negligible error current in high-impedance reference networks. |
| Temp Coefficient αVZ | +0.090 %/°C - enables predictable voltage drift compensation in wide-temperature-range systems. |
| Noise Density ND | 1 µV/√Hz - critical for low-noise analog references in instrumentation and sensor front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US (Microchip) | Same 25 V nominal Zener voltage, but commercial-grade only (no MIL qualification); DO-213AA surface-mount package. | Lacks JANTX-level screening and temperature range; unsuitable for flight-critical hardware. | Select only for cost-sensitive terrestrial industrial designs where MIL-spec is not mandated. |
| JAN1N4117 (Microsemi legacy) | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX). | Lower reliability assurance for mission-critical systems; reduced burn-in and environmental testing coverage. | Acceptable for non-safety-critical subsystems where full JANTX screening adds unnecessary cost. |
Compared with JANTX1N4117-1, the 1N4117US offers surface-mount convenience but sacrifices military reliability and temperature capability, while the JAN1N4117 provides identical form-factor and voltage performance at lower screening rigor - making JANTX1N4117-1 the sole choice for applications demanding full MIL-PRF-19500/435 JANTX compliance.

FAQ
What is the Zener voltage tolerance for JANTX1N4117-1?
JANTX1N4117-1 has a nominal Zener voltage of 25.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in Microsemi's T4-LDS-0245-2 datasheet. This tolerance applies under standard test conditions at 25 °C with 250 mA Zener test current (IZT).
Is JANTX1N4117-1 RoHS compliant?
No, JANTX1N4117-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants - JANTX-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under defense procurement exceptions.
What is the maximum reverse leakage current for JANTX1N4117-1?
The maximum reverse leakage current (IR) for JANTX1N4117-1 is 0.01 µA at VR = 19.0 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance reference applications without introducing measurable error current.
Can JANTX1N4117-1 be used in surface-mount designs?
No, JANTX1N4117-1 uses a DO-35 axial-leaded through-hole package and is not suitable for surface-mount assembly. For SMT equivalents, consider Microsemi's 1N4117UR-1 (DO-213AA) or Microchip's 1N4117US - though neither carries JANTX qualification or identical thermal performance.
What is the thermal resistance junction-to-lead for JANTX1N4117-1?
The thermal resistance junction-to-lead (RθJL) for JANTX1N4117-1 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. This value informs heatsinking requirements for continuous 500 mW operation.
