Product details
Overview
JAN1N4114-1/TR from Microsemi is a 20.0 V, ±5% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded 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 JAN1N4114-1/TR datasheet, JAN1N4114-1/TR pinout, JAN1N4114-1/TR application, or JAN1N4114-1/TR equivalent, key selection criteria include Zener voltage stability over temperature (αVZ = +0.090 %/°C), low reverse leakage (IR ≤ 0.01 µA @ VR = 15.2 V), dynamic impedance (ZZT = 150 Ω @ IZT = 250 mA), and hermetic glass packaging for radiation-hardened operation.
Technical Context
This Zener diode operates in reverse breakdown with cathode band indicating polarity, requiring banded end positive relative to anode for regulation. It delivers stable 20.0 V reference under DC current from 15.2 mA to 40 mA, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length.
Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical at lower voltages) and minimal capacitance (≈2.5 pF at 20 V), while RoHS compliance applies only to commercial-grade variants-not JAN-level parts like JAN1N4114-1/TR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 20.0 V @ IZT = 250 mA - precise regulation point for mid-range reference designs |
| Zener Tolerance | ±5% - standard JEDEC tolerance enabling cost-effective precision without tighter-bin sorting |
| Power Dissipation | 500 mW @ TC = +25 °C - supports robust operation in conduction-limited linear regulators |
| Dynamic Impedance ZZT | 150 Ω @ IZT - determines output voltage variation under load transients |
| Reverse Leakage IR | ≤0.01 µA @ VR = 15.2 V - ensures negligible current draw in standby or sensing circuits |
| Temp. Coefficient αVZ | +0.090 %/°C - enables predictable drift compensation in wide-temperature military systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4114US-1 | Same 20.0 V Zener, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy repair | Select when board space is constrained and automated placement is available |
| JANTXV1N4114-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (enhanced screening) | Higher cost and longer lead time; required only for mission-critical subsystems with burn-in and lot acceptance testing | Select only if program specification mandates JANTXV-level reliability documentation |
Compared with JAN1N4114-1/TR, 1N4114US-1 offers footprint reduction at the expense of manual assembly compatibility, while JANTXV1N4114-1 adds screening rigor without altering regulation performance-making JAN1N4114-1/TR the optimal balance of reliability, cost, and manufacturability for most aerospace-tier applications.

FAQ
What is the Zener voltage and tolerance of JAN1N4114-1/TR?
JAN1N4114-1/TR has a nominal Zener voltage of 20.0 V with ±5% tolerance at IZT = 250 mA, per JEDEC registration and MIL-PRF-19500/435 specification. This tolerance reflects standard binning for JAN-level parts and is verified under thermal equilibrium at +25 °C ambient. The device maintains regulation within this band across its rated current range of 15.2 mA to 40 mA.
Is JAN1N4114-1/TR RoHS compliant?
No, JAN1N4114-1/TR is not RoHS compliant. RoHS compliance (e3 suffix) applies only to commercial-grade versions of this series per the datasheet; JAN-level parts like JAN1N4114-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under defense procurement waivers.
What is the maximum power dissipation and derating behavior of JAN1N4114-1/TR?
JAN1N4114-1/TR is rated for 500 mW average power dissipation at TC = +25 °C. Power must be linearly derated starting at TL = +50 °C, reaching zero at +175 °C. On a typical FR4 board, derating begins at +25 °C ambient, with usable power dropping to ~350 mW at +70 °C ambient due to thermal resistance junction-to-ambient (300 °C/W).
Does JAN1N4114-1/TR have radiation hardness certification?
Yes, JAN1N4114-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic glass package provide proven resilience to total ionizing dose (TID) up to 100 krad(Si) and displacement damage, making it suitable for low-earth orbit and nuclear instrumentation applications without additional shielding.
What is the meaning of the "TR" suffix in JAN1N4114-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4114-1/TR contains the same die, electrical specs, and JAN qualification as JAN1N4114-1, differing only in packaging format-no performance or reliability changes are introduced by the TR variant.
