Product details
Overview
JAN1N4114D-1 from Microsemi is a 500 mW, 20 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial 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 datasheet, JAN1N4114D-1 pinout, JAN1N4114D-1 application, or JAN1N4114D-1 equivalent, key selection factors include its 20 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA max reverse leakage at 15.2 V, and radiation-hardened hermetic construction suitable for harsh-environment analog reference and overvoltage protection circuits.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 20.0 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.090 %/°C and low noise density (1 µV/√Hz typical). Its metallurgical bond ensures stable breakdown characteristics across wide temperature ranges.
The JAN1N4114D-1 is rated for 500 mW average power dissipation with linear derating from 25 °C ambient, junction-to-lead thermal resistance of 250 °C/W, and maximum junction temperature of +175 °C - enabling reliable operation in conduction-cooled military chassis and space-grade power conditioning modules.

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 electrical specs but in surface-mount DO-213AA package; no axial leads | Requires SMT assembly; unsuitable for through-hole prototyping or repair | Select when board space is constrained and automated placement is available |
| JANTXV1N4114D | Identical Zener parameters and DO-35 package; JANTXV reliability level instead of JANS | Limited to non-spaceflight defense programs; lower screening cost than JANS | Select for ground-based radar or comms systems where full JANS is not mandated |
Compared with JAN1N4114D-1, 1N4114US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-solderability, while JANTXV1N4114D provides near-equivalent reliability at lower cost for terrestrial high-reliability applications.

FAQ
What is the Zener voltage tolerance of JAN1N4114D-1?
JAN1N4114D-1 has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tight tolerance applies to its nominal 20.0 V Zener voltage measured at 250 mA test current and 25 °C ambient, making it suitable for precision reference applications where post-manufacturing calibration is impractical.
Is JAN1N4114D-1 suitable for space applications?
Yes, JAN1N4114D-1 is qualified to JANS level per MIL-PRF-19500/435, the highest reliability grade for spaceflight use. Its hermetic DO-35 package, radiation hardness documented in Microsemi MicroNote 050, and guaranteed operation from -65 to +175 °C confirm suitability for satellite power systems and onboard instrumentation where single-event effects and thermal cycling are critical concerns.
What is the maximum reverse leakage current for JAN1N4114D-1?
The maximum reverse leakage current (IR) for JAN1N4114D-1 is 0.01 µA at VR = 15.2 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports battery-powered reference designs and minimizes error in high-impedance bias networks.
Does JAN1N4114D-1 have RoHS compliance?
No, JAN1N4114D-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4114D-1e3); military-grade JAN/JANTX/JANTXV/JANS variants like JAN1N4114D-1 retain tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements to ensure solderability and reliability in high-reliability assemblies.
What is the thermal resistance specification for JAN1N4114D-1?
JAN1N4114D-1 has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, and junction-to-ambient resistance (RθJA) of 300 °C/W on FR4 board with specified copper pad geometry. These values govern safe power derating - for example, power must be linearly reduced above 50 °C lead temperature to prevent exceeding 175 °C maximum junction temperature.
