Product details
Overview
JANTX1N4116-1/TR from Microsemi is a 500 mW, 24.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation. It delivers 250 mA Zener test current, 150 Ω dynamic impedance at IZT, 0.01 µA max reverse leakage at 18.3 V, and +0.090 %/°C temperature coefficient - used in precision reference and power supply feedback circuits across aerospace and defense systems.
For engineers reviewing the JANTX1N4116-1/TR datasheet, JANTX1N4116-1/TR pinout, JANTX1N4116-1/TR application, or JANTX1N4116-1/TR equivalent, key selection criteria include Zener voltage tolerance, MIL-qualified reliability grade, thermal resistance (250 °C/W junction-to-lead), noise density (≤1 µV/√Hz), and DO-35 mechanical compatibility with legacy through-hole designs.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable Zener voltage under thermal cycling and radiation exposure per MicroNote 050.
The JANTX1N4116-1/TR exhibits low noise density (≤1 µV/√Hz), minimal capacitance (~10 pF typical), and linear power derating from 500 mW at 25 °C to zero at 175 °C ambient - enabling stable regulation across wide temperature ranges without external compensation.

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 electrical specs but in DO-213AA surface-mount package; no axial leads. | Requires PCB redesign for SMT assembly; unsuitable for through-hole or wire-wrap prototyping. | Select when board space is constrained and automated placement is available. |
| JAN1N4116-1 | Identical DO-35 package and electrical parameters, but qualified only to JAN (not JANTX) reliability level per MIL-PRF-19500/435. | Lacks extended screening for vibration, thermal shock, and lot acceptance testing required in flight-critical subsystems. | Select for non-flight hardware where cost sensitivity outweighs full JANTX screening requirements. |
Compared with JANTX1N4116-1/TR, the 1N4116US-1 offers identical regulation performance in a space-saving SMT form factor, while JAN1N4116-1 provides baseline military qualification at lower cost - both require evaluation against system-level reliability and mechanical integration constraints.

FAQ
What is the Zener voltage tolerance for JANTX1N4116-1/TR?
The JANTX1N4116-1/TR has a nominal Zener voltage of 24.0 V with a standard tolerance of ±5%, as defined 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 and is consistent across all JANTX-grade units in the 1N4099–1N4135 series.
Is JANTX1N4116-1/TR RoHS compliant?
No, JANTX1N4116-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2, RoHS-compliant versions carry the "e3" suffix (e.g., 1N4116-1e3) and are available only in commercial-grade variants. The JANTX1N4116-1/TR retains traditional tin-lead plating to meet MIL-STD-750 solderability requirements for high-reliability applications.
What is the maximum Zener current IZM for JANTX1N4116-1/TR?
The maximum Zener current IZM for JANTX1N4116-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value corresponds to the current at which the device reaches its rated 500 mW power dissipation limit at 24.0 V, assuming ideal thermal conditions and proper lead mounting per JEDEC DO-35 guidelines.
Does JANTX1N4116-1/TR have radiation-hardened characteristics?
Yes, JANTX1N4116-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded construction and hermetic DO-35 glass package provide proven resilience to total ionizing dose (TID) and displacement damage, making it suitable for low-earth orbit and tactical radiation environments without additional shielding.
What is the thermal resistance junction-to-lead for JANTX1N4116-1/TR?
The thermal resistance junction-to-lead (RθJL) for JANTX1N4116-1/TR is 250 °C/W, measured with 3/8″ (10 mm) lead length from the package body, as stated in the Maximum Ratings table on page 1 of T4-LDS-0245-2. This parameter governs safe continuous power handling when leads are used as heat paths in chassis-mounted or heatsink-connected configurations.
