Product details
Overview
JANTX1N4130C-1 from Microsemi is a 500 mW, 68 V, ±2% tolerance 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 in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4130C-1 datasheet, JANTX1N4130C-1 pinout, JANTX1N4130C-1 application, or JANTX1N4130C-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference and overvoltage protection design.
Technical Context
The JANTX1N4130C-1 operates as a reverse-biased voltage regulator with nominal VZ = 68 V at IZT = 250 mA, exhibiting αVZ = +0.100 %/°C and ZZT = 700 Ω. Its metallurgical bond construction ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
It delivers low noise density of 1 µV/√Hz at 68 V (per Figure 1 test method), minimal capacitance (~1.5 pF typical per Figure 3), and is non-sensitive to ESD per MIL-STD-750 Method 1020 - enabling use in low-noise analog references and radiation-hardened systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±2% at 250 mA - defines precise regulation point for feedback loops and reference generation. |
| Power Dissipation | 500 mW at 25 °C - supports stable operation in compact through-hole designs with linear derating to zero at 175 °C. |
| Dynamic Impedance ZZT | 700 Ω at 250 mA - determines regulation stiffness under load transients; lower than 1N4129-1 (500 Ω) but higher than 1N4128-1 (400 Ω). |
| Temperature Coefficient αVZ | +0.100 %/°C - enables predictable drift compensation in wide-temperature-range instrumentation. |
| Noise Density ND | 1 µV/√Hz - critical for low-noise voltage references in precision ADCs and sensor signal chains. |
| Reverse Leakage IR | ≤0.01 µA at 54.4 V - ensures minimal current draw in standby mode for battery-backed systems. |
| Junction Temp Range | -65 °C to +175 °C - validated for extended thermal cycling in avionics and space-grade electronics. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode band marking; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to system ground or low-impedance return path; polarity must be observed to avoid forward conduction during regulation. |
| Cathode | Zener regulation terminal / Input for regulated voltage | Banded end; connected to unregulated input rail; provides stable 68 V output when reverse biased above breakdown threshold. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the Zener voltage tolerance of JANTX1N4130C-1?
JANTX1N4130C-1 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature guide. This tighter tolerance reduces calibration burden in precision power supply designs compared to standard ±5% variants like JANTX1N4130-1, and is verified per MIL-PRF-19500/435 test requirements.
Is JANTX1N4130C-1 suitable for high-temperature operation?
Yes, JANTX1N4130C-1 is rated for junction temperatures from -65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgically bonded construction and hermetic DO-35 package ensure stable VZ and low leakage even under sustained thermal stress in avionics and radar systems.
Does JANTX1N4130C-1 meet RoHS requirements?
No, JANTX1N4130C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e3 suffix) are available only for commercial-grade parts (e.g., 1N4130C-1e3), not for JAN/JANTX/JANTXV/JANS military-qualified variants like JANTX1N4130C-1, which retain tin-lead plating for solderability and reliability per MIL-STD-750.
What is the maximum reverse leakage current for JANTX1N4130C-1?
The maximum reverse leakage current (IR) for JANTX1N4130C-1 is 0.01 µA at VR = 54.4 V (80% of VZ), as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This ultra-low leakage supports energy-efficient standby modes in battery-powered defense electronics.
How does the noise performance of JANTX1N4130C-1 compare to lower-voltage Zeners?
JANTX1N4130C-1 exhibits 1 µV/√Hz noise density at 68 V, consistent with the trend that higher-voltage Zeners in this family show lower noise - e.g., 6.8 V parts measure 40 µV/√Hz, dropping rapidly below 10 V. This makes JANTX1N4130C-1 especially valuable in low-noise reference applications where filtering is impractical.
