Product details
Overview
JAN1N4114-1 from Microsemi is a 500 mW, 20.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 150 Ω dynamic impedance, low 0.01 µA reverse leakage at 15.2 V, and +0.090 %/°C temperature coefficient-used in precision reference and power supply feedback circuits for aerospace avionics.
For engineers reviewing the JAN1N4114-1 datasheet, JAN1N4114-1 pinout, JAN1N4114-1 application, or JAN1N4114-1 equivalent, key selection criteria include Zener voltage tolerance, junction temperature range (–65 °C to +175 °C), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and MIL-qualified reliability level.
Technical Context
This device operates as a two-terminal voltage reference in reverse-bias breakdown mode, with regulation established at IZT = 250 mA. Its internal metallurgical bond ensures mechanical robustness and long-term stability under thermal cycling and radiation exposure.
The Zener voltage exhibits a positive temperature coefficient of +0.090 %/°C above 20 V, enabling predictable drift compensation in high-reliability analog circuits. Dynamic impedance is specified at 150 Ω under 10% rms AC modulation superimposed on IZT, confirming low AC impedance for ripple suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 20.0 V ±5% at 250 mA - defines nominal regulation point with tight tolerance for reference accuracy |
| Power Dissipation | 500 mW at TC = 25 °C - supports continuous operation in compact axial-mount designs with linear derating to zero at 175 °C |
| Dynamic Impedance ZZT | 150 Ω at 250 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage IR | 0.01 µA at VR = 15.2 V - guarantees negligible current draw in standby or high-impedance bias networks |
| Temp Coefficient αVZ | +0.090 %/°C - enables predictable voltage drift compensation in wide-temperature environments |
| Noise Density ND | 1 µV/√Hz at 250 mA - provides ultra-low broadband noise for precision analog references |
| Junction Temp Range | –65 °C to +175 °C - meets extended environmental requirements for military and space-grade systems |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode indicated by band; leads are tin-lead plated and solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse-biased operation requires cathode at higher potential |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated voltage node; polarity must be observed to avoid forward conduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4114US | Same 20 V Zener voltage but in surface-mount DO-213AA package; 400 mW rating; no MIL qualification | Lacks JAN-level screening and extended temperature validation; unsuitable for flight-critical hardware | Select when board space is constrained and commercial-grade reliability suffices |
| JANTXV1N4114 | Identical electrical specs and DO-35 package; qualified to JANTXV level per MIL-PRF-19500/435 with enhanced screening | Higher burn-in, temperature cycling, and lot acceptance testing vs. JAN grade | Select for mission-critical subsystems requiring extended life validation and zero-defect history |
Compared with JAN1N4114-1, 1N4114US trades MIL reliability for SMT compatibility and lower cost, while JANTXV1N4114 adds process rigor without altering regulation performance-enabling tiered qualification matching program risk profiles.

FAQ
What is the Zener voltage tolerance for JAN1N4114-1?
JAN1N4114-1 has a nominal Zener voltage of 20.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with IZT = 250 mA.
Is JAN1N4114-1 RoHS compliant?
No, JAN1N4114-1 is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions-not JAN-level parts. JAN1N4114-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum reverse leakage current for JAN1N4114-1?
The maximum reverse leakage current (IR) for JAN1N4114-1 is 0.01 µA at VR = 15.2 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value is measured at 25 °C and reflects the device's ultra-low leakage essential for high-impedance reference nodes.
Does JAN1N4114-1 require heatsinking in typical applications?
No, JAN1N4114-1 does not require external heatsinking in typical applications. With RθJL = 250 °C/W and PM(AV) = 500 mW at TC = 25 °C, it can dissipate full rated power using standard 3/8″ lead length per MIL-PRF-19500/435 mounting-verified in thermal derating curve Figure 2.
What packaging options are available for JAN1N4114-1?
JAN1N4114-1 is supplied in the axial-leaded DO-35 (DO-204AH) glass package only. Alternate packages like DO-213AA (1N4114UR-1) or DO-216 (1PMT4114) exist for commercial variants, but JAN1N4114-1 is exclusively offered in DO-35 per the manufacturer's qualification scope.
