Product details
Overview
JANTXV1N4131D-1 from Microsemi is a 75 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4131D-1 datasheet, JANTXV1N4131D-1 pinout, JANTXV1N4131D-1 application, or JANTXV1N4131D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 75 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 700 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current (1–40 mA) and temperature (–65 to +175 °C) ranges.
Designed for high-reliability analog references, it delivers low reverse leakage (≤0.01 µA at 60 V), minimal capacitance (~5.1 pF), and inherent radiation hardness per Microsemi MicroNote 050 - critical for space-qualified power conditioning and sensor biasing circuits where long-term parametric stability is mandatory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4131US-1 | Same 75 V, 1% spec, but in surface-mount DO-213AA package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap. | Select when board space is constrained and automated placement is available. |
| JANS1N4131D-1 | Identical electrical specs and DO-35 package, but qualified to higher JANS reliability level with additional screening. | Required for Class S (spaceflight) programs; adds cost and lead time vs. JANTXV. | Select only when JANS-level documentation and lot traceability are mandated by program requirements. |
Compared with JANTXV1N4131D-1, the 1N4131US-1 offers identical regulation performance in a compact SMT form factor, while JANS1N4131D-1 provides enhanced reliability assurance for mission-critical deployments - both require no circuit redesign but differ in mechanical integration and qualification scope.

Manufacturer
Microsemi Corporation (now part of Microchip Technology) is a U.S.-based semiconductor company specializing in high-reliability analog and mixed-signal components for aerospace, defense, and industrial markets.
The 1N4099–1N4135 series was designed specifically to meet MIL-PRF-19500/435 requirements for ruggedized, low-noise Zener regulation in harsh-environment electronics where long-term parametric stability and radiation tolerance are non-negotiable.
FAQ
What is the Zener voltage tolerance of JANTXV1N4131D-1?
JANTXV1N4131D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where VZ = 75 V at IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration overhead in precision reference designs compared to standard 5% variants like JANTXV1N4131-1.
Is JANTXV1N4131D-1 suitable for space applications?
Yes, JANTXV1N4131D-1 is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to MIL-PRF-19500/435 JANTXV level, making it suitable for low-earth orbit missions. While not Class S (JANS), its metallurgical bond construction and hermetic DO-35 package provide proven TID resilience - JANTXV1N4131D-1 has been deployed in multiple CubeSat power systems requiring stable 75 V bias under radiation exposure.
What is the maximum reverse leakage current for JANTXV1N4131D-1?
The maximum reverse leakage current (IR) for JANTXV1N4131D-1 is 0.01 µA at VR = 60 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This ultra-low leakage supports high-impedance bias networks in precision instrumentation, ensuring minimal current diversion from sensitive analog nodes in systems using JANTXV1N4131D-1 as a reference source.
Does JANTXV1N4131D-1 have a defined noise density specification?
Yes, JANTXV1N4131D-1 has a noise density of 1 µV/√Hz, consistent with all 1N4128–1N4135 devices per the Electrical Characteristics table. This value is measured at 1 kHz–3 kHz bandwidth with IZT = 250 mA and 25 °C ambient, and is critical for low-noise analog front-ends - JANTXV1N4131D-1's 1 µV/√Hz performance directly enables high-resolution sensor signal conditioning without added filtering.
What is the thermal derating behavior of JANTXV1N4131D-1?
JANTXV1N4131D-1 linearly derates from 500 mW at 25 °C to zero at 175 °C junction temperature, as shown in Figure 2 of T4-LDS-0245-2. Derating begins at TL = 50 °C for lead-temperature conditions, but for typical PCB mounting, full 500 mW is usable up to 25 °C ambient, then decreases by ~3.33 mW/°C thereafter - this behavior is fully characterized and validated for JANTXV1N4131D-1 across its qualified temperature range.
