Product details
Overview
JANTX1N4131C-1 from Microsemi is a 500 mW, 75 V Zener diode with ±2% voltage tolerance, metallurgically bonded glass construction in DO-35 package, rated for -65°C to +175°C operation, and qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace power supplies.
For engineers reviewing the JANTX1N4131C-1 datasheet, JANTX1N4131C-1 pinout, JANTX1N4131C-1 application, or JANTX1N4131C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and MIL-spec thermal derating behavior.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with a nominal Zener voltage of 75 V at 250 mA test current and dynamic impedance of 700 Ω at that point. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
The JANTX1N4131C-1 exhibits a positive temperature coefficient of +0.100 %/°C and maximum reverse leakage of 0.01 µA at 60 V, supporting stable regulation across wide temperature ranges without external compensation circuits.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 75 V ±2% at 250 mA - enables precise reference generation for 72–78 V regulated rails |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in compact axial-leaded layouts with linear derating to zero at 175 °C |
| Dynamic Impedance (ZZT) | 700 Ω at IZT = 250 mA - limits output voltage variation under load transients in feedback-sensing applications |
| Noise Density | 1 µV/√Hz - minimizes broadband noise injection into sensitive analog references or PLL loops |
| Temperature Coefficient | +0.100 %/°C - provides predictable, monotonic VZ drift over -65°C to +175°C for mission-critical thermal environments |
| Reverse Leakage (IR) | 0.01 µA at 60 V - ensures negligible standby current in high-impedance bias networks |
| Junction Temp Range | -65°C to +175°C - validated for extended operation in avionics, downhole, and space-grade electronics |

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 Zener voltage and ±2% tolerance, 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 |
| JANTXV1N4131C-1 | Identical electrical specs but qualified to JANTXV level (enhanced screening, 100% burn-in, tighter parametric limits) | Required for flight-critical subsystems where failure modes demand extended life testing and lot traceability | Select when program requirements mandate JANTXV-level reliability documentation |
Compared with JANTX1N4131C-1, the 1N4131US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-solderability, while JANTXV1N4131C-1 delivers identical functionality with enhanced screening rigor for mission-critical deployments.

FAQ
What is the Zener voltage tolerance of JANTX1N4131C-1?
JANTX1N4131C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its actual breakdown voltage falls within 73.5 V to 76.5 V at 250 mA test current and 25 °C, enabling tighter regulation than standard ±5% variants like JANTX1N4131-1.
Is JANTX1N4131C-1 suitable for high-temperature operation?
Yes, JANTX1N4131C-1 is rated for junction temperatures from -65°C to +175°C and is qualified per MIL-PRF-19500/435. Its metallurgically bonded construction and hermetic DO-35 package maintain stable Zener voltage and low leakage up to 175°C, making it appropriate for downhole, engine-mounted, and avionics applications.
Does JANTX1N4131C-1 have radiation hardness?
Yes, JANTX1N4131C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgical bond and glass package provide resistance to total ionizing dose (TID) and displacement damage, supporting use in space and nuclear environments without additional shielding.
What is the maximum reverse leakage current for JANTX1N4131C-1?
JANTX1N4131C-1 specifies a maximum reverse leakage current (IR) of 0.01 µA at 60 V, measured at 25 °C. This ultra-low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision reference applications.
Can JANTX1N4131C-1 be used in surface-mount designs?
No-JANTX1N4131C-1 uses an axial-leaded DO-35 (DO-204AH) package and is not surface-mount compatible. For SMT equivalents, consider the 1N4131US-1 in DO-213AA or 1PMT4131 in DO-216, both sharing identical 75 V ±2% Zener characteristics but differing in leadform and qualification level.
