Product details
Overview
JANTX1N4616-1/TR from Microsemi is a 500 mW, 2.2 V Zener diode in DO-35 glass package, qualified to JANTX reliability level per MIL-PRF-19500/435. It delivers 2.2 V regulation at 250 mA test current, with 1% voltage tolerance, 1300 Ω dynamic impedance, and -0.075 %/°C temperature coefficient - used for precision low-voltage reference and biasing in military-grade power supplies.
For engineers reviewing the JANTX1N4616-1/TR datasheet, JANTX1N4616-1/TR pinout, JANTX1N4616-1/TR application, or JANTX1N4616-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), hermetic DO-35 packaging, MIL-qualified thermal stability (-65 °C to +175 °C), and axial-leaded mounting compatibility with legacy high-reliability PCB layouts.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded junction construction, enabling stable regulation across wide current (250 mA IZT) and temperature (-65 °C to +175 °C) ranges. Its 1300 Ω dynamic impedance at 250 mA and 1 µV/√Hz noise density support low-drift analog circuitry.
The JANTX1N4616-1/TR is specified for lead-temperature derating from 500 mW at 25 °C to zero at 175 °C, with 250 °C/W junction-to-lead thermal resistance under 10 mm lead length conditions - critical for thermal design in conduction-cooled military modules.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4616US-1 | Same electrical specs but in DO-213AA surface-mount package - no axial leads, smaller footprint. | Used where board space is constrained and reflow assembly replaces through-hole insertion. | Select when migrating to SMT production or reducing mechanical stress on leads in vibration-prone environments. |
| JAN1N4616-1 | Identical electrical and thermal specs, but qualified only to JAN level - less stringent screening than JANTX. | Suitable for non-critical subsystems where full JANTX reliability is not mandated by program requirements. | Select when cost sensitivity outweighs need for extended burn-in and radiation lot acceptance testing. |
Compared with JANTX1N4616-1/TR, the 1N4616US-1 offers identical regulation performance in a surface-mount form factor ideal for modern compact designs, while JAN1N4616-1 provides baseline military qualification at lower cost - both require review of thermal layout and mounting constraints before substitution.

FAQ
What is the Zener voltage tolerance for JANTX1N4616-1/TR?
JANTX1N4616-1/TR has a nominal Zener voltage of 2.2 V with ±1% tolerance, as indicated by the "D" suffix in the nomenclature per the Microsemi T4-LDS-0245-2 datasheet. This tight tolerance is achieved through post-process binning and is verified during JANTX-level screening. The JANTX1N4616-1/TR maintains this specification across its rated operating temperature range.
Is JANTX1N4616-1/TR RoHS compliant?
No, JANTX1N4616-1/TR is not RoHS compliant. Per the Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JANTX-qualified devices. The JANTX1N4616-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements and maintain legacy process compatibility.
What is the maximum Zener test current for JANTX1N4616-1/TR?
The maximum Zener test current IZT for JANTX1N4616-1/TR is 250 mA, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This current defines the operating point at which VZ = 2.2 V and ZZT = 1300 Ω are measured. The JANTX1N4616-1/TR is rated for continuous operation at this current only when thermal conditions (e.g., lead length, ambient temperature) comply with derating curves.
How does the temperature coefficient affect JANTX1N4616-1/TR performance?
JANTX1N4616-1/TR has a temperature coefficient αVZ of -0.075 %/°C, meaning its Zener voltage decreases by approximately 1.65 mV per °C rise above 25 °C. This predictable drift enables compensation in precision analog designs. The JANTX1N4616-1/TR's coefficient remains stable across its full -65 °C to +175 °C junction temperature range, supporting accurate modeling in thermal-aware systems.
What packaging option does JANTX1N4616-1/TR use, and what does "TR" signify?
JANTX1N4616-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package, and the "TR" suffix indicates tape-and-reel packaging per EIA-296 standard. This format supports automated through-hole insertion and ensures consistent orientation (cathode band aligned) during placement. The JANTX1N4616-1/TR's glass body and metallurgical bond remain unchanged from bulk-packaged variants - only the carrier differs.
