Product details
Overview
JANTX1N4108C-1/TR from Microsemi is a 14.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTX1N4108C-1/TR datasheet, JANTX1N4108C-1/TR pinout, JANTX1N4108C-1/TR application, or JANTX1N4108C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for radiation-hardened analog design, avionics biasing, and regulated supply monitoring.
Technical Context
This device operates as a two-terminal reverse-biased voltage reference with a nominal Zener voltage of 14.0 V at 250 mA test current (IZT), exhibiting +0.085 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Designed for operation in the Zener breakdown region, it delivers low noise density (1 µV/√Hz typical at lower voltages), minimal capacitance (~2.5 pF at 14 V), and ESD immunity per MIL-STD-750 Method 1020 - enabling use in sensitive analog front-ends and high-stability reference chains where parametric drift must be minimized.

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, 2% spec, but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process and eliminates through-hole mounting flexibility | Select when board space constraints mandate surface-mount and thermal pad layout supports 250 °C solder profile |
| JAN1N4108C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN (not JANTX) level per MIL-PRF-19500/435 | Lacks extended screening for burn-in, life test, and lot acceptance required for JANTX-grade programs | Select only for non-mission-critical commercial-aerospace prototypes where full JANTX documentation is not mandated |
Compared with JANTX1N4108C-1/TR, 1N4108US-1 offers footprint reduction at the cost of assembly compatibility, while JAN1N4108C-1 provides identical performance with reduced reliability assurance - making JANTX1N4108C-1/TR the sole choice for production JANTX-level designs requiring full traceability and screening.

FAQ
What is the Zener voltage tolerance and test current for JANTX1N4108C-1/TR?
JANTX1N4108C-1/TR has a nominal Zener voltage of 14.0 V with ±2% tolerance, measured at a Zener test current (IZT) of 250 mA. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, and the C suffix in the part number explicitly denotes the 2% grade. The device maintains regulation within this band across its rated junction temperature range.
Is JANTX1N4108C-1/TR RoHS compliant?
No, JANTX1N4108C-1/TR is not RoHS compliant. Per the nomenclature table on page 2 of T4-LDS-0245-2 Rev. 1, RoHS compliance (e3 suffix) is available only on commercial-grade versions; JANTX-level parts like JANTX1N4108C-1/TR retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements and avoid lead-free reflow compatibility issues in high-reliability assemblies.
What is the maximum power dissipation and derating behavior of JANTX1N4108C-1/TR?
JANTX1N4108C-1/TR has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at 175 °C. As specified in the Maximum Ratings table (page 1), derating begins at 50 °C for lead temperature (TL) and at 25 °C for ambient (TA) on a typical FR4 board - meaning usable power drops to ~375 mW at 75 °C ambient, ensuring safe operation in high-temperature enclosures without forced cooling.
Does JANTX1N4108C-1/TR have radiation hardness certification?
Yes, JANTX1N4108C-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and silicon die design provide resistance to total ionizing dose (TID), making it suitable for low-earth orbit (LEO) satellite applications and nuclear facility instrumentation where single-event effects and cumulative dose must be mitigated without additional shielding.
What does the "TR" suffix indicate in JANTX1N4108C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. As noted on page 2 of T4-LDS-0245-2 Rev. 1, this option is available for JANTX1N4108C-1/TR and requires consultation with the factory for minimum order quantities. The TR suffix does not affect electrical or reliability specifications - it is purely a packaging designation for manufacturing logistics.
