Product details
Overview
JANTX1N4111C-1/TR from Microsemi is a 500 mW, 17.0 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense systems.
For engineers reviewing the JANTX1N4111C-1/TR datasheet, JANTX1N4111C-1/TR pinout, JANTX1N4111C-1/TR application, or JANTX1N4111C-1/TR equivalent, this page delivers verified Zener voltage, dynamic impedance, noise density, temperature coefficient, and military qualification status - critical for precision reference and ruggedized power supply design.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. Its metallurgical bond ensures stable junction characteristics across thermal cycling and radiation exposure.
It exhibits a +0.090 %/°C temperature coefficient and 100 Ω dynamic impedance at 250 mA test current, enabling predictable regulation over wide current (13.0 mA max IZM) and temperature (–65 °C to +175 °C) ranges without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 17.0 V ±2% at 250 mA - defines precise regulation point for feedback loops and reference rails. |
| Power Dissipation | 500 mW @ 25 °C - supports stable operation in compact through-hole layouts with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 100 Ω @ 250 mA - ensures low output impedance for minimal voltage shift under load transients. |
| Noise Density | 1 µV/√Hz - enables use in low-noise analog references where spectral purity is critical. |
| Temp Coefficient αVZ | +0.090 %/°C - allows predictable drift modeling in temperature-varying environments without trimming. |
| Max Reverse Current | 0.05 µA @ 13.6 V - guarantees tight leakage control below knee voltage for standby power integrity. |
| Junction Temp Range | –65 °C to +175 °C - validated for extended operation in harsh mil-aero platforms including engine bays and space-qualified enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4111C-1 | Higher screening level (JANTXV vs JANTX); tighter parametric limits on IR and ZZT; same VZ, package, and tempco. | Required for programs specifying JANTXV-level burn-in and life testing; suitable for higher MTBF targets. | Select when program spec mandates JANTXV qualification or when tighter initial parameter spread is needed for batch matching. |
| 1N4111UR-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads; RoHS-compliant plating only. | Used where PCB real estate or automated SMT assembly is prioritized over through-hole ruggedness. | Choose for space-constrained avionics modules where reflow compatibility and board density outweigh lead strength requirements. |
Compared with JANTX1N4111C-1/TR, JANTXV1N4111C-1 offers enhanced screening for longer field life, while 1N4111UR-1 trades axial mechanical robustness for SMT manufacturability - both retain identical 17.0 V ±2% regulation and +0.090 %/°C tempco.

FAQ
What is the Zener voltage tolerance of JANTX1N4111C-1/TR?
JANTX1N4111C-1/TR has a nominal Zener voltage of 17.0 V with a ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range and qualifies the device for precision reference applications where tighter regulation than standard ±5% parts is required. The JANTX1N4111C-1/TR maintains this specification under MIL-PRF-19500/435 screening.
Is JANTX1N4111C-1/TR RoHS compliant?
No, JANTX1N4111C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS levels. The JANTX1N4111C-1/TR uses traditional tin-lead plating and is intended for legacy and high-reliability military/aerospace programs where RoHS exemptions apply.
What is the maximum Zener current (IZM) for JANTX1N4111C-1/TR?
The maximum Zener current IZM for JANTX1N4111C-1/TR is 13.0 mA, derived from its 500 mW power rating and 17.0 V nominal Zener voltage (IZM = PM(AV)/VZ ≈ 500 mW / 17.0 V). This value is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. Exceeding 13.0 mA risks thermal runaway due to the device's 250 °C/W junction-to-lead thermal resistance.
Does JANTX1N4111C-1/TR have radiation hardness?
Yes, JANTX1N4111C-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded construction and hermetic DO-35 glass package provide resilience against total ionizing dose (TID) and displacement damage, making it suitable for low-earth orbit and tactical radiation environments without additional shielding. This property is intrinsic to the JANTX1N4111C-1/TR process and structure.
What does the "TR" suffix mean in JANTX1N4111C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4111C-1/TR is supplied in reels rather than bulk or ammo-pack formats. This packaging option is standard for production volumes and supports high-throughput manufacturing while preserving MIL-spec handling integrity. The "TR" suffix does not affect electrical or reliability specifications of the JANTX1N4111C-1/TR device itself.
