Product details
Overview
JANTXV1N4111C-1/TR from Microsemi is a 500 mW, 17 V Zener voltage regulator diode in DO-35 glass package with ±2% tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTXV qualification for high-reliability aerospace and defense applications.
For engineers reviewing the JANTXV1N4111C-1/TR datasheet, JANTXV1N4111C-1/TR pinout, JANTXV1N4111C-1/TR application, or JANTXV1N4111C-1/TR equivalent, key selection factors include its 17 V nominal Zener voltage at 250 mA test current, 100 Ω dynamic impedance, 13.0 mA maximum Zener current, +0.090 %/°C temperature coefficient, and low 1 µV/√Hz noise density at lower voltages.
Technical Context
This device operates as a precision shunt voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
Designed for operation at 250 mA Zener test current (IZT), it delivers regulated output across wide current ranges (IZK to IZM) and maintains voltage stability over -65 °C to +175 °C junction temperature, supported by linear power derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications

| Nominal Zener Voltage | 17.0 V at 250 mA - defines regulation setpoint for reference and clamp circuits |
| Zener Tolerance | ±2% - tighter than standard 5% parts, enabling higher-accuracy voltage references |
| Power Dissipation | 500 mW @ TC = 25 °C - sets maximum continuous thermal load on PCB layout |
| Dynamic Impedance | 100 Ω @ IZT - determines output voltage variation under load current changes |
| Temperature Coefficient | +0.090 %/°C - quantifies drift rate of Zener voltage per degree Celsius change |
| Noise Density | 1 µV/√Hz - specifies low-frequency noise floor critical for precision analog references |
| Max Reverse Leakage | 0.05 µA @ VR = 13.0 V - ensures minimal quiescent current in standby regulation |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1/TR | Same 17 V Zener voltage and ±2% tolerance, but in surface-mount DO-213AA package; no axial leads | Used where board space is constrained and automated SMT assembly is required | Select 1N4111US-1/TR only if reflow compatibility and footprint reduction outweigh need for axial through-hole mounting |
| JANS1N4111C-1 | Identical electrical specs and DO-35 package, but qualified to JANS level (highest MIL-PRF-19500 reliability tier) | Required for mission-critical space systems where failure probability must be <10⁻⁶ per 1000 hrs | Choose JANS1N4111C-1 only when JANS-level screening, burn-in, and lot traceability are contractually mandated |

FAQ
What is the Zener voltage and tolerance of JANTXV1N4111C-1/TR?
JANTXV1N4111C-1/TR has a nominal Zener voltage of 17.0 V at 250 mA test current with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tighter tolerance supports higher-accuracy voltage references compared to standard ±5% variants like JANTXV1N4111-1/TR.
Is JANTXV1N4111C-1/TR RoHS compliant?
No, JANTXV1N4111C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and ensure reliability under thermal cycling.
What is the maximum power dissipation and derating behavior of JANTXV1N4111C-1/TR?
JANTXV1N4111C-1/TR is rated for 500 mW average power dissipation at 25 °C case temperature. Power must be linearly derated starting at 50 °C lead temperature, reaching zero at 175 °C. On a typical FR4 PCB, derating begins at 25 °C ambient and follows the same linear slope per Microsemi's Figure 2.
Does JANTXV1N4111C-1/TR have radiation hardness properties?
Yes, JANTXV1N4111C-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded junction and hermetic DO-35 package provide resistance to total ionizing dose (TID) and displacement damage, making it suitable for low-earth orbit and tactical defense platforms.
What does the "TR" suffix indicate in JANTXV1N4111C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and requires consultation with the factory for minimum order quantities and reel specifications.
