Product details
Overview
JANTXV1N4108D-1/TR from Microsemi is a 14.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4108D-1/TR datasheet, JANTXV1N4108D-1/TR pinout, JANTXV1N4108D-1/TR application, or JANTXV1N4108D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), max noise density (1 µV/√Hz), dynamic impedance (200 Ω), temperature coefficient (+0.085 %/°C), and JANTXV-level qualification for extended temperature operation.
Technical Context
This axial-leaded Zener diode operates in reverse breakdown with cathode band indicating polarity, requiring banded end positive relative to anode for regulation. It delivers stable 14.0 V reference across 250 mA test current and supports full-range regulation from 10.7 mA to 40 mA maximum Zener current.
Its metallurgical bond construction ensures low noise (1 µV/√Hz at 14 V), minimal capacitance (typical <2 pF), and inherent radiation hardness per Microsemi MicroNote 050 - critical for space-grade analog references and precision bias networks.
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 |
|---|---|---|---|
| 1N4108US-1 | Same 14.0 V ±1%, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated assembly and board space constraints outweigh manual repair needs |
| JANS1N4108D-1 | Identical electrical specs and DO-35 package, but qualified to higher JANS radiation-hardness level | Approved for Class K (spaceflight) use; requires additional screening documentation and longer lead times | Select only when mission-critical radiation tolerance beyond JANTXV is mandated |
Compared with JANTXV1N4108D-1/TR, the 1N4108US-1 offers footprint reduction at the cost of assembly flexibility, while JANS1N4108D-1 adds radiation assurance overhead without improving baseline regulation performance.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4108D-1/TR?
JANTXV1N4108D-1/TR has a nominal Zener voltage of 14.0 V with ±1% tolerance at 250 mA test current, as confirmed in the Microsemi T4-LDS-0245-2 datasheet Table on Page 3. This tight tolerance is achieved via post-trim screening and applies across the full JANTXV qualification temperature range of –65 to +175 °C.
Is JANTXV1N4108D-1/TR RoHS compliant?
No, JANTXV1N4108D-1/TR is not RoHS compliant. Per the datasheet nomenclature table, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JANTXV-level parts like JANTXV1N4108D-1/TR use traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum Zener current rating for JANTXV1N4108D-1/TR?
The maximum Zener current IZM for JANTXV1N4108D-1/TR is 40 mA, as specified in the Electrical Characteristics table on Page 3 of the datasheet. This value corresponds to the 500 mW power limit derated at 14.0 V and assumes proper thermal management per the RθJL = 250 °C/W specification.
Does JANTXV1N4108D-1/TR have radiation hardness certification?
Yes, JANTXV1N4108D-1/TR exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. While not individually tested to MIL-STD-883 methods, its metallurgically bonded glass construction and hermetic DO-35 package provide proven resilience against total ionizing dose (TID) and displacement damage in space environments.
What does the "D" in JANTXV1N4108D-1/TR signify?
The "D" in JANTXV1N4108D-1/TR indicates ±1% Zener voltage tolerance per the JEDEC nomenclature defined in the datasheet's Part Nomenclature section. It follows the reliability level "JANTXV" and precedes the RoHS indicator "-1", distinguishing it from standard ±5% ("blank") or ±2% ("C") variants.
