Product details
Overview
JAN1N4131-1 from Microsemi is a 500 mW, 75 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4131-1 datasheet, JAN1N4131-1 pinout, JAN1N4131-1 application, or JAN1N4131-1 equivalent, key selection criteria include its 75 V nominal Zener voltage at 250 mA test current, 700 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 60 V, +0.100 %/°C temperature coefficient, and radiation-hardened hermetic construction.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK and stable regulation over wide current (250 mA IZT) and temperature (-65 °C to +175 °C) ranges. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at lower voltages) and minimal capacitance.
The JAN1N4131-1 exhibits a positive temperature coefficient (+0.100 %/°C), indicating increasing Zener voltage with rising junction temperature - critical for thermal stability analysis in regulated power rails. It is rated for 500 mW average power dissipation with linear derating above 50 °C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 75 V at 250 mA test current - defines precise regulation point for reference and clamp circuits. |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous DC power handling before thermal derating begins. |
| Zener Impedance ZZT | 700 Ω max at 250 mA - determines regulation stiffness and output voltage variation under load changes. |
| Reverse Leakage IR | 0.01 µA max at 60 V - ensures minimal parasitic current in high-impedance bias networks. |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift per degree, essential for temperature-compensated designs. |
| Noise Density ND | 1 µV/√Hz typical - enables low-noise voltage references in analog signal chains and precision instrumentation. |
| Junction Temp Range | -65 °C to +175 °C - supports operation in extreme environments including space and military avionics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by color band; leads are tin-lead plated and solderable per MIL-STD-750 method 2026. Body diameter 1.42–2.29 mm, overall length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node during Zener operation; used for forward-bias testing or protection clamping. |
| Cathode (banded end) | Zener regulation terminal | Connected to higher-potential node; reverse-biased to maintain 75 V reference across load in shunt configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bonding | Enables hermetic sealing and eliminates interfacial delamination under thermal cycling and radiation exposure. |
| MIL-PRF-19500/435 qualification | Validated reliability for JAN-level screening including burn-in, temperature cycling, and life testing per military standards. |
| Radiation hardness | Inherently resistant to total ionizing dose (TID) per Microsemi MicroNote 050 - suitable for space-grade applications. |
| Low noise density | 1 µV/√Hz typical at 75 V - reduces RMS noise contribution in precision voltage references and sensor excitation circuits. |
| ESD immunity | Non-sensitive per MIL-STD-750 method 1020 - eliminates need for external ESD protection in board-level assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4131-1 | Higher screening level (JANTXV) with extended temperature testing and tighter parametric limits. | Required for mission-critical subsystems where failure modes must be statistically bounded beyond JAN requirements. | Select when full JANTXV qualification documentation and lot traceability are mandated by system-level specs. |
| 1N4131US | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Suitable only for automated SMT assembly; incompatible with through-hole PCB layouts or manual prototyping. | Choose for volume production where board space and reflow compatibility outweigh legacy mounting flexibility. |
Compared with JAN1N4131-1, JANTXV1N4131-1 offers enhanced screening rigor for safety-critical functions, while 1N4131US trades axial-leaded serviceability for SMT manufacturability - neither is pin-compatible due to differing packages and qualification scopes.

FAQ
What is the Zener voltage tolerance for JAN1N4131-1?
JAN1N4131-1 has a nominal Zener voltage of 75 V with a standard tolerance of ±5%, as specified in the JEDEC-registered electrical characteristics table. This tolerance applies under thermal equilibrium conditions at 25 °C ambient temperature with 250 mA test current, and is consistent across all JAN-level units per MIL-PRF-19500/435 screening requirements.
Is JAN1N4131-1 RoHS compliant?
No, JAN1N4131-1 is not RoHS compliant. The "e3" RoHS designation is available only on commercial-grade versions (e.g., 1N4131-1e3); JAN-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum reverse leakage current for JAN1N4131-1?
JAN1N4131-1 specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 60 V, measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and precision reference circuits where parasitic current paths must be minimized.
Can JAN1N4131-1 be used in surface-mount designs?
No, JAN1N4131-1 uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4131US in DO-213AA package - however, it lacks JAN qualification and differs in mechanical form factor and screening level.
What is the thermal resistance junction-to-lead for JAN1N4131-1?
JAN1N4131-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, per MIL-PRF-19500/435 test conditions. This value is critical for calculating junction temperature rise under actual operating power dissipation in leaded mounting configurations.
