Product details
Overview
JANTXV1N4131C-1 from Microsemi is a 500 mW, 75 V Zener diode with ±2% voltage tolerance, metallurgically bonded glass DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability aerospace and defense power regulation applications.
For engineers reviewing the JANTXV1N4131C-1 datasheet, JANTXV1N4131C-1 pinout, JANTXV1N4131C-1 application, or JANTXV1N4131C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass sealing, and military-grade thermal derating performance up to +175 °C junction temperature.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, delivering stable 75 V regulation across 250 mA test current and wide temperature range (–65 °C to +175 °C). Its metallurgical bond ensures low thermal resistance (RθJL = 250 °C/W) and minimal parameter drift under thermal cycling.
Designed for high-reliability analog circuits, it exhibits ultra-low leakage (IR ≤ 0.01 µA at VR = 60 V), dynamic impedance of 700 Ω at IZT, and a positive temperature coefficient (+0.100 %/°C) optimized for series-reference stability in regulated power supplies and sensor bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 75 V ±2% at 250 mA - enables precise mid-range voltage reference in 72–78 V systems without external trimming. |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous regulation in compact through-hole designs with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 700 Ω max at 250 mA - ensures minimal output voltage shift under load transients in feedback-sensing applications. |
| Noise Density | 1 µV/√Hz - critical for low-noise analog references in instrumentation, ADC biasing, and precision comparators. |
| Reverse Leakage IR | ≤ 0.01 µA @ 60 V - guarantees negligible current draw in standby or high-impedance sensing nodes. |
| Temp Coefficient αVZ | +0.100 %/°C - provides predictable, monotonic VZ drift for temperature-compensated reference chains. |
| Junction Temp Range | –65 °C to +175 °C - validated for operation in extreme environments including space-grade and downhole electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used as Zener regulator (cathode connected to higher potential).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Reference ground node | Connected to system ground or lower-potential rail; defines regulation reference point for VZ drop. |
| Cathode (unbanded end) | Regulated output node | Delivers stable 75 V relative to anode; must be biased positive w.r.t. anode to maintain Zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and long-term burn-in, ensuring parameter stability over 20+ year lifetimes. |
| MIL-PRF-19500/435 JANTXV qualification | Validated screening includes lot acceptance tests, burn-in, thermal cycling, and life testing per military reliability standards. |
| Hermetic glass DO-35 package | Prevents moisture ingress and ion contamination, enabling operation in humid, corrosive, or vacuum environments without conformal coating. |
| Radiation hardness | Inherently tolerant to total ionizing dose (TID) per Microsemi MicroNote 050 - suitable for low-earth orbit and nuclear instrumentation. |
| Low capacitance | Typical <1.5 pF - preserves high-frequency signal integrity in RF detector biasing and fast-switching protection circuits. |

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 ±2% spec, but in DO-213AA surface-mount package; RθJA = 400 °C/W vs. 300 °C/W for DO-35. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-power dissipation where lead conduction dominates. | Select when board space is constrained and thermal management uses copper pour rather than lead length. |
| JAN1N4131C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTXV). | Not approved for mission-critical avionics or spaceflight; acceptable for ground-test equipment and non-flight hardware. | Select for cost-sensitive development platforms where full JANTXV screening is unnecessary. |
Compared with JANTXV1N4131C-1, the 1N4131US-1 trades axial-lead mechanical robustness and superior thermal conduction for miniaturization, while JAN1N4131C-1 reduces qualification cost and lead time at the expense of radiation tolerance and extended life testing.

FAQ
What is the Zener voltage tolerance and test current for JANTXV1N4131C-1?
JANTXV1N4131C-1 has a nominal Zener voltage of 75 V with ±2% tolerance, measured at a Zener test current (IZT) of 250 mA. This tight tolerance ensures accurate voltage setting in high-reliability reference circuits without post-manufacture calibration. The device maintains this specification across its qualified temperature range and lifetime screening.
Is JANTXV1N4131C-1 RoHS compliant?
No, JANTXV1N4131C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants (e.g., 1N4131C-1e3), not for JANTXV-level qualified parts. JANTXV1N4131C-1 retains traditional tin-lead plating to meet MIL-STD-750 solderability requirements and thermal cycling performance.
What is the maximum junction temperature and thermal derating behavior of JANTXV1N4131C-1?
JANTXV1N4131C-1 has a rated junction temperature range of –65 °C to +175 °C. Its 500 mW average power dissipation linearly derates from full rating at 25 °C ambient to zero at 175 °C, with a defined slope of –3.33 mW/°C above 50 °C lead temperature. This derating curve is validated per MIL-PRF-19500/435 test methods.
How does the metallurgical bond in JANTXV1N4131C-1 improve reliability compared to standard epoxy-bonded Zeners?
The internal metallurgical bond in JANTXV1N4131C-1 eliminates organic adhesives that degrade under thermal stress or radiation exposure. This construction prevents interfacial delamination during thermal cycling, maintains consistent Zener voltage over 20+ years, and supports operation in vacuum or high-humidity environments where epoxy outgassing or moisture absorption would compromise performance.
Can JANTXV1N4131C-1 be used as a replacement for commercial 1N4131C-1 in existing designs?
JANTXV1N4131C-1 shares identical electrical parameters and DO-35 package with commercial 1N4131C-1, but adds JANTXV-level screening, extended temperature validation, and radiation hardness. It is a direct functional and mechanical replacement; however, design requalification may be required for flight or safety-critical use due to differences in screening documentation and traceability protocols.
