Product details
Overview
JANTXV1N4130C-1/TR from Microsemi is a 500 mW, 68 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability aerospace and defense systems requiring stable voltage regulation under wide temperature and current variation.
For engineers reviewing the JANTXV1N4130C-1/TR datasheet, JANTXV1N4130C-1/TR pinout, JANTXV1N4130C-1/TR application, or JANTXV1N4130C-1/TR equivalent, this page delivers verified Zener voltage, dynamic impedance, noise density, temperature coefficient, and military qualification status - all critical for precision reference, overvoltage protection, and regulated biasing in harsh-environment electronics.
Technical Context
This device operates as a two-terminal voltage reference in reverse breakdown, with a nominal Zener voltage of 68 V at 250 mA test current (IZT), dynamic impedance of 700 Ω at IZT, and low noise density of 1 µV/√Hz - optimized for low-noise analog references and stable biasing in RF and instrumentation circuits.
Its metallurgical bond construction ensures mechanical robustness and long-term stability under thermal cycling and radiation exposure, while the ±2% voltage tolerance (denoted by "C" suffix) and JANTXV qualification confirm compliance with stringent military screening including extended temperature range (–65 °C to +175 °C) and hermeticity requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the Zener voltage tolerance of JANTXV1N4130C-1/TR?
The "C" suffix in JANTXV1N4130C-1/TR denotes a ±2% Zener voltage tolerance at 25 °C, measured at the 250 mA test current (IZT). This tighter tolerance reduces calibration effort in precision reference designs compared to standard ±5% variants like JANTXV1N4130-1/TR.
Is JANTXV1N4130C-1/TR RoHS compliant?
No - JANTXV1N4130C-1/TR uses traditional tin-lead plating and is not RoHS compliant. RoHS-compliant versions (e.g., with "e3" suffix) are available only on commercial-grade parts per the datasheet; military-grade JANTXV devices retain leaded finishes for solderability and reliability per MIL-STD-750.
What is the maximum reverse leakage current for JANTXV1N4130C-1/TR?
JANTXV1N4130C-1/TR has a maximum reverse leakage current (IR) of 10 nA at VR = 54.4 V (80% of nominal VZ), per the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This ultra-low leakage supports high-impedance bias networks without loading error.
Does JANTXV1N4130C-1/TR require heatsinking in typical applications?
No - JANTXV1N4130C-1/TR is rated for 500 mW at 25 °C ambient with no heatsink, using standard 3/8″ lead length. Its RθJL = 250 °C/W allows direct mounting on FR4 PCBs with minimal copper area; derating begins linearly at 50 °C lead temperature, reaching zero dissipation at 175 °C.
How does the noise performance of JANTXV1N4130C-1/TR compare to lower-voltage Zeners?
JANTXV1N4130C-1/TR exhibits 1 µV/√Hz noise density at 250 mA - consistent with the datasheet trend showing noise falling rapidly below 6.8 V. While lower-voltage Zeners (e.g., 5.1 V) reach ~0.5 µV/√Hz, JANTXV1N4130C-1/TR's 1 µV/√Hz remains among the lowest available for 68 V references, supporting sensitive analog measurement systems.
