Product details
Overview
JANS1N4116-1/TR from Microsemi is a 500 mW, 24.0 V Zener diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±5% voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4116-1/TR datasheet, JANS1N4116-1/TR pinout, JANS1N4116-1/TR application, or JANS1N4116-1/TR equivalent, this page provides verified electrical specs, thermal derating behavior, noise density (1 µV/√Hz), radiation-hardened performance, and military-grade packaging details critical for precision voltage reference and regulation in harsh-environment systems.
Technical Context
This device functions as a metallurgically bonded, hermetically sealed Zener voltage regulator with cathode band polarity marking. Its internal bond structure ensures stable breakdown characteristics under thermal cycling and radiation exposure, supporting operation up to 175 °C junction temperature.
It exhibits low noise density (1 µV/√Hz at 24 V), minimal capacitance (typical <2 pF), and a positive temperature coefficient of +0.090 %/°C - enabling predictable voltage drift compensation in analog reference circuits and power supply feedback paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same 24 V Zener voltage and JANS qualification, but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; lacks axial leads for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated placement is required |
| JANTXV1N4116-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (lower screening rigor than JANS) | Approved for airborne but not spaceflight or nuclear applications per MIL-PRF-19500/435 Table I | Select for cost-sensitive avionics where full JANS screening is not mandated |
Compared with JANS1N4116-1/TR, the 1N4116US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4116-1 reduces cost and lead time at the expense of radiation hardness and extended life testing - making each suitable for distinct tiers of mission-critical deployment.

FAQ
What is the Zener voltage tolerance for JANS1N4116-1/TR?
JANS1N4116-1/TR has a nominal Zener voltage of 24.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with 250 mA test current.
Does JANS1N4116-1/TR require heatsinking in typical applications?
No, JANS1N4116-1/TR does not require external heatsinking in standard operation. Its 500 mW power rating and 250 °C/W junction-to-lead thermal resistance allow safe dissipation at ambient temperatures ≤50 °C. Derating begins linearly above that point, reaching zero power at 175 °C junction temperature - consistent with its intended use in thermally managed mil-spec enclosures.
Is JANS1N4116-1/TR RoHS compliant?
No, JANS1N4116-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is available only on commercial-grade versions. JANS-level devices like JANS1N4116-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under EU Directive 2011/65/EU Annex III.
What is the maximum reverse leakage current for JANS1N4116-1/TR?
The maximum reverse leakage current (IR) for JANS1N4116-1/TR is 0.01 µA at 18.3 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This ultra-low leakage supports high-impedance bias networks in precision analog circuits without introducing measurable error.
How is polarity marked on JANS1N4116-1/TR?
JANS1N4116-1/TR uses a single black cathode band on the glass body to indicate polarity. During Zener regulation, the banded end (cathode) must be held positive relative to the unmarked end (anode). This marking conforms to JEDEC DO-35 standards and is verified in the Mechanical and Packaging section on page 2 of T4-LDS-0245-2 Rev. 1.
