Product details
Overview
JANTX1N4130D-1 from Microsemi is a 1% tolerance, 68 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4130D-1 datasheet, JANTX1N4130D-1 pinout, JANTX1N4130D-1 application, or JANTX1N4130D-1 equivalent, key selection factors include its 1% Zener voltage tolerance, 700 Ω dynamic impedance at 250 mA, 0.01 µA reverse leakage at 54.4 V, radiation-hardened construction, and DO-35 axial-leaded hermetic package compatibility with legacy military PCB layouts.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with Zener voltage specified at 250 mA test current (IZT) and temperature coefficient of +0.100 %/°C. Its metallurgical bond ensures stable long-term voltage regulation under thermal cycling and mechanical stress.
It exhibits low noise density (1 µV/√Hz typical at lower voltages), minimal capacitance (~5.6 pF), and is non-sensitive to ESD per MIL-STD-750 Method 1020 - making it suitable for low-noise reference and critical biasing applications where parametric stability across temperature and radiation environments is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68.0 V ±1% at 250 mA - enables precise 68 V rail regulation with tight tolerance for mission-critical analog references. |
| Power Dissipation | 500 mW at 25 °C - supports stable operation in compact, convection-cooled military enclosures without forced airflow. |
| Dynamic Impedance ZZT | 700 Ω max at 250 mA - ensures minimal output voltage shift under load transients in feedback-sensing circuits. |
| Reverse Leakage IR | 0.01 µA max at 54.4 V - guarantees negligible current draw in standby or high-impedance sensing nodes. |
| Temp Coefficient αVZ | +0.100 %/°C - provides predictable, monotonic voltage drift over -65 to +175 °C operating range. |
| Noise Density ND | 1 µV/√Hz typical - supports ultra-low-noise voltage references in precision instrumentation front-ends. |
| Junction Temp Range | -65 to +175 °C - meets extended environmental requirements for avionics, space-grade, and downhole electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or common return; forms low-impedance path for Zener current sink. |
| Cathode | Regulated output node | Banded end; supplies stable 68 V when reverse-biased; must be held positive relative to anode. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4130D-1 | JAN-level qualification (lower screening than JANTX); same electrical specs and DO-35 package. | Suitable for less stringent reliability requirements; not approved for flight-critical subsystems. | Select when full JANTX screening is unnecessary and cost sensitivity is higher. |
| 1N4130UR-1 | DO-213AA surface-mount package; identical 68 V/1% spec but no military qualification. | Used in commercial or industrial PCBs where reflow assembly and space constraints preclude axial leads. | Choose for automated SMT production where MIL-spec is not mandated and board real estate is limited. |
Compared with JAN1N4130D-1, JANTX1N4130D-1 offers enhanced screening for vibration, thermal shock, and burn-in - critical for airborne platforms; versus 1N4130UR-1, it trades SMT compatibility for hermeticity, radiation hardness, and guaranteed performance across extreme temperatures.

FAQ
What is the Zener voltage tolerance of JANTX1N4130D-1?
JANTX1N4130D-1 has a nominal Zener voltage of 68.0 V with a tight ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and is maintained across its full operating temperature range due to its metallurgical bond construction and JANTX-level screening.
Is JANTX1N4130D-1 radiation hardened?
Yes, JANTX1N4130D-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide resistance to total ionizing dose (TID) effects, making JANTX1N4130D-1 suitable for use in space and nuclear environments without additional shielding or derating.
What is the maximum reverse leakage current for JANTX1N4130D-1?
The maximum reverse leakage current (IR) for JANTX1N4130D-1 is 0.01 µA at 54.4 V (80% of nominal VZ), as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage ensures minimal power loss and high impedance stability in precision reference applications using JANTX1N4130D-1.
Does JANTX1N4130D-1 have a surface-mount alternative?
Yes - the 1N4130UR-1 is the surface-mount counterpart of JANTX1N4130D-1, housed in a DO-213AA package and offering identical 68 V ±1% Zener voltage. However, 1N4130UR-1 lacks MIL-PRF-19500/435 qualification and radiation hardness, so it is intended only for commercial or industrial use, not for systems requiring JANTX1N4130D-1's military-grade reliability.
What is the thermal resistance junction-to-lead for JANTX1N4130D-1?
JANTX1N4130D-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured with 3/8 inch (10 mm) lead length from the body, per the Maximum Ratings table. This value enables accurate thermal modeling for lead-mounted heatsinking in high-power-density military chassis where ambient temperature exceeds 50 °C.
