Product details
Overview
JANTXV1N4111D-1/TR from Microsemi is a 17.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supply circuits.
For engineers reviewing the JANTXV1N4111D-1/TR datasheet, JANTXV1N4111D-1/TR pinout, JANTXV1N4111D-1/TR application, or JANTXV1N4111D-1/TR equivalent, key selection criteria include its 17.0 V nominal Zener voltage at 250 mA test current, 100 Ω maximum dynamic impedance, 0.05 µA maximum reverse leakage at 13.0 V, and radiation-hardened hermetic construction suitable for harsh-environment analog reference and overvoltage protection designs.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 17.0 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.090 %/°C and noise density of 1 µV/√Hz - optimized for low-noise analog references. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The JANTXV1N4111D-1/TR is rated for 500 mW average power dissipation at TL = 25 °C, derating linearly to zero at 175 °C, with junction-to-lead thermal resistance of 250 °C/W and junction-to-ambient of 300 °C/W on standard FR4 board layout - enabling reliable operation in conduction-cooled avionics subsystems.
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 |
|---|---|---|---|
| 1N4111US-1 | Same 17.0 V/1% spec but in surface-mount DO-213AA package; no axial leads. | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or wire-wrap. | Select when automated assembly, board space constraints, or vibration resistance are prioritized over manual serviceability. |
| JANTXV1N4111C-1/TR | Identical 17.0 V rating and DO-35 package, but ±2% tolerance instead of ±1%. | Acceptable for non-critical biasing where tighter regulation is not required; lower cost. | Choose when system-level calibration compensates for tolerance, or when budget limits drive part selection without sacrificing reliability grade. |
Compared with JANTXV1N4111D-1/TR, the 1N4111US-1 offers identical electrical specs in a smaller footprint but eliminates field-replaceability, while JANTXV1N4111C-1/TR trades 1% precision for cost savings - making the D-grade optimal for uncalibrated, high-stability analog references.

FAQ
What is the Zener voltage tolerance of JANTXV1N4111D-1/TR?
JANTXV1N4111D-1/TR has a ±1% Zener voltage tolerance at 25 °C, meaning its actual breakdown voltage falls within 16.83 V to 17.17 V when tested at 250 mA. This tight tolerance is achieved through post-process binning and is maintained across the full -65 °C to +175 °C operating junction temperature range per MIL-PRF-19500/435 requirements. The 'D' suffix in the part number explicitly denotes this 1% grade.
Is JANTXV1N4111D-1/TR suitable for space applications?
Yes, JANTXV1N4111D-1/TR is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to JANTXV level under MIL-PRF-19500/435, which includes total ionizing dose (TID) testing up to 100 krad(Si). Its hermetic DO-35 glass package prevents moisture ingress and outgassing in vacuum, making it suitable for LEO satellite power regulation and reference functions - though full radiation lot acceptance testing must be confirmed per purchase order.
What is the maximum reverse leakage current for JANTXV1N4111D-1/TR?
The maximum reverse leakage current for JANTXV1N4111D-1/TR is 0.05 µA measured at VR = 13.0 V and 25 °C, as specified in the Electrical Characteristics table. This ultra-low leakage ensures minimal loading on high-impedance reference nodes and preserves accuracy in precision analog circuits such as instrumentation amplifiers and ADC voltage references where even nanoamp-level errors degrade performance.
Does JANTXV1N4111D-1/TR require derating at elevated temperatures?
Yes, JANTXV1N4111D-1/TR must be derated linearly from 500 mW starting at TL = 50 °C, reaching zero power at 175 °C, per Figure 2 in the datasheet. On a typical FR4 PCB, derating begins at 25 °C ambient due to thermal resistance limitations (RθJA = 300 °C/W), requiring careful thermal design - especially in enclosed avionics enclosures where ambient may exceed 70 °C and power dissipation must be limited to ~350 mW.
What does the 'TR' suffix indicate in JANTXV1N4111D-1/TR?
The 'TR' suffix in JANTXV1N4111D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. It does not affect electrical or reliability specifications. The part remains fully compliant with MIL-PRF-19500/435 JANTXV requirements and retains the same 1% Zener tolerance, 17.0 V rating, and DO-35 package dimensions as the bulk version - only the packaging format differs for manufacturing efficiency.
