Product details
Overview
JAN1N4131-1/TR from Microsemi is a 75 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435, with 1% Zener voltage tolerance, 700 Ω dynamic impedance at 250 mA, and 0.01 µA reverse leakage at 60 V. It regulates voltage in high-reliability power supply reference circuits across military avionics and space-grade instrumentation.
For engineers reviewing the JAN1N4131-1/TR datasheet, JAN1N4131-1/TR pinout, JAN1N4131-1/TR application, or JAN1N4131-1/TR equivalent, key selection criteria include its JANS qualification, 75 V nominal Zener voltage with ±1% tolerance, 500 mW power rating, DO-35 axial-leaded hermetic package, and low noise density (1 µV/√Hz) at regulated output.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with Zener test current fixed at 250 mA and dynamic impedance measured at 10% AC modulation superimposed on IZT. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
The diode exhibits a +0.100 %/°C temperature coefficient above 68 V, enabling predictable drift compensation in wide-temperature-range analog systems. Reverse leakage is specified at ≤0.01 µA up to 60 V, supporting ultra-low-power biasing in high-impedance sensing nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4131US | Same 75 V Zener voltage and JANS qualification, but in DO-213AA surface-mount package | Requires PCB re-layout for SMT assembly; no axial lead mounting option | Select when automated pick-and-place manufacturing and board space reduction are priorities |
| JANTXV1N4131-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS) | Lacks full radiation hardness certification; unsuitable for spaceflight missions | Select for high-reliability ground-based military systems where cost sensitivity outweighs space qualification needs |
Compared with JAN1N4131-1/TR, 1N4131US offers identical regulation performance in a compact SMT form factor but eliminates axial mounting flexibility, while JANTXV1N4131-1 reduces procurement cost and lead time at the expense of JANS-level radiation assurance required for orbital deployment.

FAQ
What is the Zener voltage tolerance of JAN1N4131-1/TR?
JAN1N4131-1/TR has a nominal Zener voltage of 75 V with ±1% tolerance, as indicated by the "D" suffix in its nomenclature per Microsemi's part numbering convention. This tight tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where it is listed under the 1N4131-1 row with "D" denoting 1% Zener voltage tolerance.
Is JAN1N4131-1/TR qualified to JANS level?
Yes, JAN1N4131-1/TR is qualified to JANS level per MIL-PRF-19500/435, as explicitly stated in the "Qualified Levels" section on page 1 and confirmed in the "PART NOMENCLATURE" table where "JAN" prefix denotes JAN-level qualification and full JANS compliance is supported for this series. The device meets requirements for radiation hardness and extended temperature operation.
What is the maximum Zener test current for JAN1N4131-1/TR?
The maximum Zener test current for JAN1N4131-1/TR is 250 mA, as specified in the "ELECTRICAL CHARACTERISTICS" table on page 3 of T4-LDS-0245-2 Rev. 1. This current is used to measure VZ, ZZT, and other parameters under standardized thermal equilibrium conditions at 25 °C ambient temperature.
Does JAN1N4131-1/TR have RoHS compliance?
No, JAN1N4131-1/TR is not RoHS compliant. Per the "PART NOMENCLATURE" table on page 2, RoHS compliance (denoted by "e3" suffix) is available only on commercial-grade versions; the "JAN" prefix indicates military-grade qualification, and the absence of "e3" confirms non-RoHS lead-tin plating per MIL-STD-750 method 2026.
What is the thermal resistance junction-to-lead for JAN1N4131-1/TR?
The thermal resistance junction-to-lead (RθJL) for JAN1N4131-1/TR is 250 °C/W, measured at 3/8 inch (10 mm) lead length from body, as specified in the "MAXIMUM RATINGS" table on page 1 of T4-LDS-0245-2 Rev. 1. This value assumes standard mounting per JEDEC DO-35 thermal test conditions.
