Product details
Overview
JANTX1N4117C-1 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 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4117C-1 datasheet, JANTX1N4117C-1 pinout, JANTX1N4117C-1 application, or JANTX1N4117C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (150 Ω at 250 mA), temperature coefficient (+0.090 %/°C), noise density (1 µV/√Hz), and JANTX-level qualification for extended temperature operation.
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. Its metallurgical bond construction ensures stable breakdown characteristics and low long-term drift under thermal cycling.
It exhibits a positive temperature coefficient of +0.090 %/°C, low dynamic impedance (150 Ω), minimal reverse leakage (≤10 nA at 19.0 V), and ultra-low noise density (1 µV/√Hz), making it suitable for reference-grade analog circuits requiring stable DC biasing.
Key Specifications

| Dynamic Impedance ZZT | 150 Ω at IZT = 250 mA - ensures tight voltage regulation under varying load current |
| Temperature 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 and precision instrumentation front-ends |
| Reverse Leakage IR | ≤10 nA at 19.0 V - minimizes error current in high-impedance bias networks |
| Junction Temp Range | –65 °C to +175 °C - supports operation in harsh military and space environments |

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 surface-mount DO-213AA package; no axial leads | Used where board space is constrained and reflow assembly is required | Select when transitioning from through-hole to SMT manufacturing or when lead inductance must be minimized |
| JAN1N4117C-1 | Identical electrical and mechanical specs but qualified only to JAN level (less stringent screening than JANTX) | Acceptable for less critical subsystems where full JANTX burn-in and life test not mandated | Select when cost sensitivity outweighs requirement for extended reliability screening and lot traceability |
Compared with JANTX1N4117C-1, the 1N4117US-1 offers identical regulation performance in a smaller footprint but requires PCB redesign, while JAN1N4117C-1 reduces procurement cost and lead time at the expense of reduced reliability assurance for mission-critical functions.

FAQ
What is the Zener voltage tolerance for JANTX1N4117C-1?
JANTX1N4117C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a nominal 25.0 V Zener voltage ranging from 24.5 V to 25.5 V at 250 mA test current and 25 °C ambient, verified per MIL-PRF-19500/435 screening.
Is JANTX1N4117C-1 RoHS compliant?
No, JANTX1N4117C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JANTX-qualified parts. The JANTX1N4117C-1 uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum Zener current IZM for JANTX1N4117C-1?
The maximum Zener current IZM for JANTX1N4117C-1 is 40 mA, derived from its 500 mW power rating and 25 V nominal Zener voltage (P = V × I → I = 0.5 W / 25 V = 20 mA), with derating applied per Figure 2 in the datasheet. At 25 °C, IZM is 40 mA, decreasing linearly to zero at 175 °C junction temperature.
How does the temperature coefficient of JANTX1N4117C-1 affect its regulation accuracy?
JANTX1N4117C-1 has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 22.5 mV per 10 °C rise above 25 °C. This predictable positive drift allows system designers to compensate in feedback networks or select complementary components, unlike lower-voltage Zeners with negative coefficients.
Can JANTX1N4117C-1 be used in surface-mount designs?
No, JANTX1N4117C-1 is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT equivalents, Microsemi offers the 1N4117US-1 in DO-213AA package - same electrical specs but with solderable surface-mount terminals instead of axial leads.
