Product details
Overview
JANTX1N4131D-1 from Microsemi is a 500 mW, 75 V Zener diode with 1% voltage tolerance, metallurgically bonded glass DO-35 package, qualified to JANTX level per MIL-PRF-19500/435, used for precision voltage regulation in military and aerospace power supply reference circuits.
For engineers reviewing the JANTX1N4131D-1 datasheet, JANTX1N4131D-1 pinout, JANTX1N4131D-1 application, or JANTX1N4131D-1 equivalent, key selection criteria include Zener voltage (75 V), tolerance (±1%), dynamic impedance (700 Ω at 250 mA), noise density (1 µV/√Hz), and JANTX-level reliability qualification for high-reliability embedded systems.
Technical Context
This device operates as a reverse-biased voltage reference diode with a nominal Zener voltage of 75 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and temperature coefficient (+0.100 %/°C). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling.
It is rated for 500 mW average power dissipation with linear derating from 25 °C to zero at 175 °C, and features hermetically sealed DO-35 glass packaging with cathode band polarity marking - optimized for stable DC reference generation in analog signal chains and regulated power rails.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4131D-1 | JANS qualification (higher screening level than JANTX); identical electrical specs and DO-35 package. | Required for Class S spaceflight hardware; not needed for airborne or ground-based military systems. | Select JANS1N4131D-1 only if full JANS screening per MIL-PRF-19500/435 is mandated by program requirements. |
| 1N4131UR-1 | DO-213AA surface-mount package; same 75 V/1% spec but no JANTX qualification; RoHS compliant. | Suitable for commercial or industrial PCBs where automated assembly and smaller footprint are prioritized over military reliability. | Choose 1N4131UR-1 for volume production on FR4 boards with reflow compatibility and lower cost, excluding high-reliability programs. |
Compared with JANTX1N4131D-1, JANS1N4131D-1 adds full radiation and burn-in screening for space use, while 1N4131UR-1 trades qualification for SMT manufacturability - enabling selection based on reliability tier and assembly process rather than electrical performance.

FAQ
What is the Zener voltage tolerance of JANTX1N4131D-1?
JANTX1N4131D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This corresponds to a 75 V nominal Zener voltage ranging from 74.25 V to 75.75 V at 250 mA test current and 25 °C ambient, verified per MIL-PRF-19500/435 screening.
Is JANTX1N4131D-1 qualified to JANTX reliability level?
Yes, JANTX1N4131D-1 is fully qualified to the JANTX level per MIL-PRF-19500/435, including extended temperature testing, life testing, and lot acceptance procedures. This qualification ensures suitability for high-reliability military and aerospace applications where failure modes must be rigorously controlled.
What is the maximum Zener current IZM for JANTX1N4131D-1?
The maximum Zener current IZM for JANTX1N4131D-1 is 57.0 mA, calculated from its 500 mW power rating and 75 V Zener voltage (P = V × I). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, and assumes operation at 25 °C lead temperature with appropriate derating above that point.
Does JANTX1N4131D-1 have radiation hardness properties?
Yes, JANTX1N4131D-1 exhibits inherent radiation hardness due to its metallurgically bonded glass construction and silicon die design, as documented in Microsemi MicroNote 050. It is suitable for low-to-moderate total ionizing dose (TID) environments typical in LEO spacecraft and avionics, though full radiation test reports require direct request from Microchip.
What package type does JANTX1N4131D-1 use?
JANTX1N4131D-1 uses the DO-35 (also designated DO-204AH) axial-leaded hermetically sealed glass package, with overall length between 25.4 mm and 38.1 mm and body diameter between 1.42 mm and 2.29 mm, per the Package Dimensions drawing on page 5 of T4-LDS-0245-2 Rev. 1.
