Product details
Overview
JANTXV1N4131D-1/TR from Microsemi is a 75 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4131D-1/TR datasheet, JANTXV1N4131D-1/TR pinout, JANTXV1N4131D-1/TR application, or JANTXV1N4131D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (≤1 µV/√Hz), temperature coefficient (+0.100 %/°C), and military-grade qualification level.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-bias 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 construction ensures stable regulation across wide current and temperature ranges.
It exhibits low noise density (≤1 µV/√Hz), minimal capacitance (typ. <1.5 pF), and radiation hardness per Microsemi MicroNote 050. The cathode band marking defines polarity, and operation requires the banded end to be positive relative to the anode for regulation.

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 Zener voltage and tolerance, but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; lacks axial-leaded mechanical robustness | Select when board space is constrained and automated placement is required |
| JANS1N4131D-1 | Identical electrical specs, but qualified to JANS (highest MIL-PRF-19500 level) with extended screening | Used only in Class-S spaceflight hardware; higher cost and longer lead time | Select when full JANS qualification and lot traceability are mandated by program requirements |
Compared with JANS1N4131D-1, the JANTXV1N4131D-1/TR offers identical regulation performance at lower cost and shorter lead time, while 1N4131US-1 trades axial-mount ruggedness for SMT compatibility-neither is pin-compatible due to differing packages.

FAQ
What is the Zener voltage tolerance of JANTXV1N4131D-1/TR?
JANTXV1N4131D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where 1N4131-1 lists VZ = 75 V at IZT = 250 mA with D = 1% tolerance. The JANTXV1N4131D-1/TR inherits this specification as a qualified variant of the base 1N4131-1 part.
Is JANTXV1N4131D-1/TR RoHS compliant?
No, JANTXV1N4131D-1/TR is not RoHS compliant. Per the nomenclature table on page 2 of T4-LDS-0245-2, RoHS compliance (e3 suffix) is available only on commercial-grade versions. JANTXV-level parts like JANTXV1N4131D-1/TR use tin-lead plating and are exempt from RoHS per MIL-PRF-19500 requirements. The "TR" suffix indicates tape-and-reel packaging, not RoHS status.
What is the maximum Zener test current for JANTXV1N4131D-1/TR?
The maximum Zener test current for JANTXV1N4131D-1/TR is 250 mA, as specified in the Electrical Characteristics table for 1N4131-1. This value is consistent across all variants in the 1N4099–1N4135-1 family, including JANTXV1N4131D-1/TR. The device is rated for 500 mW dissipation at 25 °C lead temperature, supporting operation at this current level within thermal limits.
Does JANTXV1N4131D-1/TR have radiation hardness?
Yes, JANTXV1N4131D-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050 referenced in the Applications/Benefits section. Its metallurgically bonded glass construction and DO-35 hermetic package provide tolerance to total ionizing dose (TID) environments without parameter shift-making it suitable for space and nuclear applications without additional shielding.
What does the "TR" suffix mean in JANTXV1N4131D-1/TR?
The "TR" suffix in JANTXV1N4131D-1/TR indicates tape-and-reel packaging per EIA-296 standard, as stated in the Mechanical and Packaging section on page 2 of T4-LDS-0245-2. It does not denote RoHS compliance or any electrical change. The "TR" version is functionally identical to JANTXV1N4131D-1 but supplied in automated assembly-ready format for high-volume manufacturing.
