Product details
Overview
JANTX1N4114C-1 from Microsemi is a 500 mW, 20 V ±2% 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, reference circuits, and overvoltage protection.
For engineers reviewing the JANTX1N4114C-1 datasheet, JANTX1N4114C-1 pinout, JANTX1N4114C-1 application, or JANTX1N4114C-1 equivalent, key selection criteria include its 20 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA maximum reverse leakage at 15.2 V, and radiation-hardened hermetic glass construction.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee (IZK) and stable regulation across wide current (250 mA IZT, up to 40 mA IZM) and temperature (–65 °C to +175 °C) ranges. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at 20 V) and minimal capacitance per Figure 3.
The JANTX reliability grade mandates screening per MIL-PRF-19500/435, including burn-in, thermal shock, and life testing. The DO-35 axial-leaded package supports through-hole mounting with cathode band polarity marking and tin-lead plating compliant with MIL-STD-750 Method 2026.
Key Specifications

|---|---|
| Nominal Zener Voltage | 20.0 V ±2% at 250 mA - defines precise regulation point for reference and clamp applications |
| Power Dissipation | 500 mW @ TC = 25 °C - sets maximum continuous thermal load before derating begins at 50 °C |
| Zener Impedance | 150 Ω max at 250 mA - determines output voltage stability under varying load current |
| Reverse Leakage | 0.01 µA max at 15.2 V - ensures minimal standby current in high-impedance bias networks |
| Temp Coefficient | +0.090 %/°C - quantifies voltage drift with ambient temperature change in precision references |
| Noise Density | 1 µV/√Hz typical - enables low-noise performance in analog reference and sensing circuits |
| Junction Temp Range | –65 °C to +175 °C - supports operation in extreme environmental conditions without derating |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with hermetically sealed body, 0.2 g mass, and cathode indicated by colored band. Leads are tin-lead plated and solderable per MIL-STD-750 Method 2026.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4114US-1 | Same 20 V ±2% Zener, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy designs | Select when board space is constrained and automated placement is available |
| JANTXV1N4114C-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening (e.g., 100% lot acceptance testing) | Required for programs demanding extended reliability validation beyond JANTX, such as missile guidance subsystems | Select when program specification explicitly requires JANTXV or higher qualification level |
Compared with JANTX1N4114C-1, the 1N4114US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4114C-1 provides stricter process controls and test coverage-both serve distinct mechanical and assurance requirements without altering core Zener functionality.

FAQ
What is the Zener voltage tolerance of JANTX1N4114C-1?
JANTX1N4114C-1 has a nominal Zener voltage of 20.0 V with a tolerance of ±2%, denoted by the "C" suffix in the part number. This tighter tolerance reduces calibration effort in precision reference circuits compared to standard ±5% variants like JANTX1N4114-1.
Is JANTX1N4114C-1 suitable for high-temperature operation?
Yes, JANTX1N4114C-1 is rated for junction temperatures from –65 °C to +175 °C and is fully characterized across this range. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C, making it suitable for engine bay or downhole electronics where ambient extremes occur.
Does JANTX1N4114C-1 meet RoHS requirements?
No, JANTX1N4114C-1 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 qualified devices like JANTX1N4114C-1.
What is the maximum Zener current for JANTX1N4114C-1?
The maximum Zener current (IZM) for JANTX1N4114C-1 is 40 mA, specified at 25 °C lead temperature. This value reflects the highest continuous DC current the device can sustain while remaining within its 500 mW power limit and thermal resistance constraints.
How is polarity marked on JANTX1N4114C-1?
JANTX1N4114C-1 uses a cathode band marking on the glass body to indicate polarity. During Zener regulation, the banded (cathode) end must be held at a higher potential than the anode end-i.e., the cathode connects to the unregulated input rail and the anode to the regulated output/reference node.
