Product details
Overview
JAN1N4114D-1/TR from Microsemi is a 20 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4114D-1/TR datasheet, JAN1N4114D-1/TR pinout, JAN1N4114D-1/TR application, or JAN1N4114D-1/TR equivalent, this page delivers verified Zener voltage (20.0 V), dynamic impedance (150 Ω), temperature coefficient (+0.090 %/°C), noise density (1 µV/√Hz), and JANS qualification status - all critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a two-terminal shunt voltage regulator with cathode-banded polarity, requiring reverse bias for Zener conduction. Its metallurgical bond ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range and enables low-noise performance (1 µV/√Hz at 20 V) and minimal capacitance.
It exhibits a positive temperature coefficient of +0.090 %/°C and is rated for 250 mA Zener test current (IZT), with maximum Zener current (IZM) of 40 mA and dynamic impedance (ZZT) of 150 Ω measured at 10% AC modulation superimposed on IZT - confirming suitability for stable reference generation under varying load and thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 20.0 V ±1% at 250 mA - precise regulation point for reference circuits requiring tight tolerance. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - defines thermal design margin for PCB layout and heatsinking. |
| Dynamic Impedance ZZT | 150 Ω at 250 mA - low output impedance ensures minimal voltage shift under load variation. |
| Noise Density ND | 1 µV/√Hz - ultra-low broadband noise critical for precision analog references and metrology systems. |
| Temperature Coefficient αVZ | +0.090 %/°C - predictable positive drift enables accurate temperature-compensated reference design. |
| Reverse Leakage IR | 0.01 µA at 15.2 V - negligible leakage preserves accuracy in high-impedance bias networks. |
| Junction Temp Range | -65 °C to +175 °C - supports operation in extreme environments including space-grade and military platforms. |

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/TR | Same 20 V, 1% Zener voltage but in surface-mount DO-213AA package; no JANS qualification. | Lacks MIL-PRF-19500/435 screening; suitable only for commercial or industrial surface-mount designs. | Select when board space is constrained and radiation/harsh-environment requirements are absent. |
| JANTXV1N4114D-1/TR | Identical electrical specs and DO-35 package; qualified to JANTXV level (not JANS); lower screening rigor and radiation assurance. | Approved for high-reliability military avionics but not spaceflight or nuclear applications. | Select when full JANS qualification is unnecessary but extended temperature and burn-in screening are required. |
Compared with JAN1N4114D-1/TR, the 1N4114US-1/TR offers footprint reduction at the cost of environmental robustness, while JANTXV1N4114D-1/TR provides accelerated qualification at lower cost and reduced radiation assurance - making JAN1N4114D-1/TR the sole choice for mission-critical space and nuclear systems.

Yes, JAN1N4114D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including rigorous screening for radiation hardness, thermal cycling, mechanical shock, and long-term parametric stability - making it suitable for spaceflight and nuclear applications where failure is not an option.
What is the maximum Zener current IZM for JAN1N4114D-1/TR?
The maximum Zener current (IZM) for JAN1N4114D-1/TR is 40 mA, derived from its 500 mW power rating and 20 V Zener voltage (P = V × I). This limit applies at 25 °C lead temperature and must be linearly derated above 50 °C per the published power derating curve.
Does JAN1N4114D-1/TR have low-noise performance?
Yes, JAN1N4114D-1/TR delivers ultra-low noise density of 1 µV/√Hz at 20 V, measured in the 1 kHz–3 kHz band with 250 mA DC bias. This performance is enabled by its metallurgical bond construction and makes it ideal for precision analog references in metrology and instrumentation systems.
What package type and marking does JAN1N4114D-1/TR use?
JAN1N4114D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by a band. It is marked with the full part number "JAN1N4114D-1" and supplied in tape-and-reel format (TR suffix), compliant with EIA-296 standards.
