Product details
Overview
JANTXV1N4117D-1 from Microsemi is a 25 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4117D-1 datasheet, JANTXV1N4117D-1 pinout, JANTXV1N4117D-1 application, or JANTXV1N4117D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, and military-grade thermal derating behavior up to +175 °C junction temperature.
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, exhibiting a dynamic impedance of 150 Ω and temperature coefficient of +0.090 %/°C. Its metallurgical bond construction ensures stable regulation across wide current (1–40 mA) and temperature (−65 to +175 °C) ranges.
Designed for high-reliability analog reference and biasing circuits, it delivers minimal capacitance (<10 pF), non-ESD-sensitive operation per MIL-STD-750 Method 1020, and inherent radiation hardness validated per Microsemi MicroNote 050 - critical for space-qualified power conditioning and avionics subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 25.0 V ±1% at IZT = 250 mA - enables precise reference generation with tight tolerance for feedback loops in regulated DC-DC converters. |
| Power Rating | 500 mW at TL = 25 °C, linearly derated to zero at 175 °C - supports sustained operation in high-temperature military enclosures without forced cooling. |
| Dynamic Impedance ZZT | 150 Ω at IZT = 250 mA - ensures low output impedance for stable regulation under varying load currents in analog sensor bias networks. |
| Noise Density | 1 µV/√Hz - provides ultra-low noise voltage reference for precision instrumentation amplifiers and ADC reference buffers. |
| Temp Coefficient αVZ | +0.090 %/°C - predictable positive drift allows compensation in temperature-critical voltage references used in inertial navigation systems. |
| Reverse Leakage IR | ≤0.01 µA at VR = 19.0 V - guarantees negligible standby current draw in battery-backed backup regulators and low-power telemetry circuits. |
| Junction Temp Range | −65 to +175 °C - meets extended environmental requirements for airborne radar power supplies and missile guidance electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package with cathode indicated by band; operated with banded end positive for Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference Ground Node | Connected to system ground or common return path; serves as the reference potential for Zener regulation. |
| Cathode | Regulated Output Terminal | Delivers stable 25 V output when reverse-biased; must be held at higher potential than anode to maintain breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Guarantees screening, testing, and traceability per U.S. military reliability standards - required for DoD procurement and flight-critical hardware. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling and mechanical shock - essential for launch-vibration environments. |
| 1% Zener voltage tolerance (D suffix) | Reduces calibration overhead in precision analog circuits; avoids post-manufacture trimming in avionics voltage references. |
| Inherent radiation hardness | Validated per Microsemi MicroNote 050 - enables use in low-earth orbit (LEO) satellite power management without additional shielding or mitigation. |
| Non-ESD-sensitive per MIL-STD-750 Method 1020 | Allows safe handling in standard assembly lines without special ESD controls - reduces manufacturing cost and process complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4117US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or repair. | Select when board space is constrained and reflow compatibility is mandatory. |
| 1N4117UR-1 | Commercial-grade (non-military) version; same 25 V/1% specs but only JAN/JANTX qualified, not JANTXV. | Lacks JANTXV screening and radiation hardness validation; limited to non-flight or ground-test use. | Select for lab evaluation or non-critical subsystems where full military qualification is unnecessary. |
Compared with JANTXV1N4117D-1, JANTXV1N4117US-1 offers identical regulation performance in a compact SMT form factor, while 1N4117UR-1 provides cost-effective evaluation capability without military screening - enabling staged qualification paths from prototype to flight hardware.
