Product details
Overview
JAN1N4114C-1/TR from Microsemi is a 20 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4114C-1/TR datasheet, JAN1N4114C-1/TR pinout, JAN1N4114C-1/TR application, or JAN1N4114C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), low noise density (1 µV/√Hz), JANS-qualified thermal stability (–65 °C to +175 °C), and axial-leaded DO-35 mechanical robustness for harsh-environment mounting.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 20.0 V at 250 mA test current, exhibiting a temperature coefficient of +0.090 %/°C and dynamic impedance of 150 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling.
Designed for operation in the reverse-biased breakdown region, it delivers regulated output with minimal capacitance (<1.5 pF typical at 20 V) and low leakage (≤0.01 µA at VR = 16.0 V), supporting stable reference generation in analog signal chains and power supply feedback loops.
Key Specifications

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 voltage but in surface-mount DO-213AA package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap boards. | Select when automated assembly and board space reduction are prioritized over manual repairability. |
| JANTXV1N4114C-1 | Identical electrical specs but qualified to JANTXV level with extended screening and tighter lot traceability. | Required for programs mandating JANTXV compliance (e.g., DoD contracts with MIL-STD-883 Class B). | Select when full JANTXV documentation, burn-in, and radiation test reports are contractually required. |
Compared with JAN1N4114C-1/TR, 1N4114US-1 offers footprint miniaturization at the cost of mechanical serviceability, while JANTXV1N4114C-1 adds screening rigor without altering regulation performance-enabling trade-offs between logistics simplicity and program compliance depth.

FAQ
What is the Zener voltage tolerance of JAN1N4114C-1/TR?
JAN1N4114C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its nominal 20.0 V Zener voltage is guaranteed between 19.6 V and 20.4 V at 250 mA test current and 25 °C ambient, meeting MIL-PRF-19500/435 requirements for high-reliability applications.
Is JAN1N4114C-1/TR RoHS compliant?
JAN1N4114C-1/TR is available in RoHS-compliant versions (designated by "e3" suffix), though the JAN reliability level typically uses tin-lead plating. For RoHS compliance, confirm ordering with "JAN1N4114C-1/TR e3"; standard JAN1N4114C-1/TR uses annealed matte-tin plating per MIL-STD-750 method 2026.
What is the maximum reverse leakage current for JAN1N4114C-1/TR?
JAN1N4114C-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at VR = 16.0 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports low-power standby modes in battery-backed systems.
Can JAN1N4114C-1/TR be used in surface-mount designs?
No-JAN1N4114C-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider 1N4114US-1 in DO-213AA or 1PMT4114 in DO-216; these share identical electrical specs but require different PCB footprints and reflow profiles.
What is the thermal resistance junction-to-lead for JAN1N4114C-1/TR?
JAN1N4114C-1/TR has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured with 3/8″ (10 mm) lead length from body, per the Maximum Ratings table. This value enables accurate junction temperature calculation during derating analysis for high-temperature enclosure designs.
