Product details
Overview
JANTX1N4105D-1/TR from Microsemi is a 1% tolerance, 11.0 V Zener voltage regulator diode in DO-35 glass axial package, rated for 500 mW power dissipation, with 200 Ω dynamic impedance at 250 mA test current and +0.080 %/°C temperature coefficient - used for precision voltage reference and regulation in military-grade power supply feedback loops.
For engineers reviewing the JANTX1N4105D-1/TR datasheet, JANTX1N4105D-1/TR pinout, JANTX1N4105D-1/TR application, or JANTX1N4105D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), MIL-PRF-19500/435 JANTX qualification level, DO-35 thermal resistance (250 °C/W junction-to-lead), noise density (≤1 µV/√Hz), and radiation-hardened construction for aerospace and defense systems.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded junction, delivering stable 11.0 V regulation across 5–100 mA operating current range and -65 °C to +175 °C junction temperature. Its low 200 Ω dynamic impedance ensures minimal voltage deviation under load transients.
The JANTX1N4105D-1/TR exhibits +0.080 %/°C temperature coefficient and ≤0.05 µA reverse leakage at 8.5 V, enabling predictable drift compensation in analog circuits. Hermetic glass DO-35 packaging supports high-reliability operation without moisture-induced parameter shift.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1 | Same 11.0 V, 1% tolerance, but in DO-213AA surface-mount package; RθJL = 300 °C/W vs. 250 °C/W for DO-35 | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mounting | Select when automated assembly and board space constraints outweigh thermal performance needs |
| JAN1N4105D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Lacks JANTX-level burn-in and life test data; not approved for Class H or Class K military programs | Select only for cost-sensitive commercial-aerospace derivatives where full JANTX screening is not mandated |
Compared with JANTX1N4105D-1/TR, the 1N4105US-1 trades thermal performance for SMT compatibility, while JAN1N4105D-1 reduces qualification rigor to lower cost - neither offers drop-in replacement without verifying screening compliance or thermal derating margins.

FAQ
What is the Zener voltage and tolerance of JANTX1N4105D-1/TR?
JANTX1N4105D-1/TR has a nominal Zener voltage of 11.0 V with ±1% tolerance at 250 mA test current. This tight tolerance is achieved via post-process binning and verified during JANTX-level screening. The 1% spec ensures minimal unit-to-unit variation in critical feedback paths where resistor trimming is impractical.
Is JANTX1N4105D-1/TR RoHS compliant?
No, JANTX1N4105D-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS-compliant versions, which are only available for commercial-grade parts (blank reliability level). JANTX-level devices retain leaded terminations per MIL-STD-750 Method 2026 to ensure solder joint integrity under thermal cycling and mechanical shock.
What is the maximum operating temperature for JANTX1N4105D-1/TR?
JANTX1N4105D-1/TR supports junction temperatures from -65 °C to +175 °C. Derating begins linearly at +50 °C ambient (or +50 °C lead temperature), reducing power dissipation from 500 mW to zero at +175 °C. This wide range enables deployment in engine-mounted avionics and downhole oilfield electronics.
How does the temperature coefficient affect JANTX1N4105D-1/TR performance?
JANTX1N4105D-1/TR has a +0.080 %/°C temperature coefficient, meaning its Zener voltage increases by approximately 8.8 mV per °C rise. This predictable positive drift allows designers to compensate using complementary NTC networks or select adjacent Zener voltages to achieve near-zero net TC in multi-diode references.
What packaging and marking does JANTX1N4105D-1/TR use?
JANTX1N4105D-1/TR uses a hermetically sealed DO-35 (DO-204AH) glass axial package with cathode indicated by a single black band. The part is marked "1N4105D-1" and supplied in tape-and-reel format with "TR" suffix per EIA-296 standard, supporting automated placement while maintaining MIL-spec handling integrity.
