Product details
Overview
JANTXV1N4131C-1/TR from Microsemi is a 75 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTXV1N4131C-1/TR datasheet, JANTXV1N4131C-1/TR pinout, JANTXV1N4131C-1/TR application, or JANTXV1N4131C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), temperature coefficient (+0.100 %/°C), and JANTXV-level qualification for extended temperature operation (-65 °C to +175 °C).
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 75 V at 250 mA test current, dynamic impedance of 700 Ω at IZT, and maximum reverse leakage current of 0.01 µA at VR = 60 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling.
Designed for high-reliability environments, it features hermetically sealed DO-35 packaging, RoHS-compliant matte-tin plating (commercial grade only), and radiation-hardened behavior per Microsemi MicroNote 050 - all validated under MIL-STD-750 test methods including ESD immunity (Method 1020) and solderability (Method 2026).
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 |
|---|---|---|---|
| JANTXV1N4131US-1/TR | Same electrical specs but in DO-213AA surface-mount package instead of DO-35 axial lead | Required for automated SMT assembly; lacks axial mounting flexibility and manual prototyping ease | Select when board space constraints or reflow-only production mandate SMT packaging |
| JANS1N4131C-1/TR | Identical electrical and mechanical specs, but qualified to JANS (highest MIL-PRF-19500/435 level) with additional radiation and lot traceability requirements | Necessary for nuclear-hardened systems and manned spacecraft where JANS certification is mandated | Select when mission-critical radiation tolerance and full lot traceability are required beyond JANTXV |
Compared with JANTXV1N4131C-1/TR, the DO-213AA variant enables higher-density layouts but sacrifices hand-soldering capability, while the JANS version adds radiation assurance and documentation rigor at higher cost and longer lead time - both retain identical 75 V ±2% regulation and 1 µV/√Hz noise performance.

FAQ
What is the Zener voltage tolerance of JANTXV1N4131C-1/TR?
JANTXV1N4131C-1/TR has a nominal Zener voltage of 75 V with a tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range (-65 °C to +175 °C) and validated during JANTXV-level qualification testing per MIL-PRF-19500/435.
Is JANTXV1N4131C-1/TR RoHS compliant?
JANTXV1N4131C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (marked with "e3") are available only on commercial-grade parts, not on JANTXV-qualified devices. The JANTXV1N4131C-1/TR uses traditional tin-lead plating on its leads to meet MIL-STD-750 solderability requirements for high-reliability applications.
What is the maximum reverse leakage current for JANTXV1N4131C-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4131C-1/TR is 0.01 µA at VR = 60 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance bias networks and long-hold-time sample-and-hold circuits without significant drift.
Does JANTXV1N4131C-1/TR require heatsinking in standard operation?
JANTXV1N4131C-1/TR does not require external heatsinking at 500 mW dissipation below 50 °C lead temperature. Its thermal resistance junction-to-lead is 250 °C/W with 10 mm lead length, and power must be linearly derated above 50 °C - reaching zero at 175 °C. PCB copper area alone suffices for most avionics applications within spec.
How is polarity marked on JANTXV1N4131C-1/TR?
JANTXV1N4131C-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for Zener regulation. This marking follows JEDEC DO-35 standards and is visible on the glass body; incorrect orientation results in forward conduction (~1.1 V drop) rather than regulation.
