Product details
Overview
JANTX1N4130-1 from Microsemi is a 500 mW, 68 V metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level, with 1% Zener voltage tolerance, 700 Ω maximum dynamic impedance at 250 mA test current, and 40 µA maximum reverse leakage at 54.4 V.
For engineers reviewing the JANTX1N4130-1 datasheet, JANTX1N4130-1 pinout, JANTX1N4130-1 application, or JANTX1N4130-1 equivalent, this part serves as a high-reliability voltage reference in aerospace power conditioning, radiation-hardened sensor biasing, and precision analog supply regulation where stable breakdown voltage and low noise density (≤1 µV/√Hz) are critical.
Technical Context
This device operates in reverse-biased Zener breakdown mode with cathode band marking polarity. Its metallurgical bond construction ensures mechanical robustness and thermal stability across -65 °C to +175 °C junction temperature range, supporting operation under extreme thermal cycling and shock environments.
It delivers 68 V nominal regulation at 250 mA test current (IZT), with ±1% tolerance (D-grade), 5.6 mA maximum Zener current (IZM), and +0.100 %/°C temperature coefficient - enabling predictable drift compensation in high-temperature avionics subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4130US (Microchip) | Same 68 V, 1% tolerance, but in surface-mount DO-213AA package; no MIL qualification | Lacks JANTX-level screening, burn-in, and radiation hardness data; suitable only for commercial industrial designs | Select when board space is constrained and military reliability documentation is not required |
| JAN1N4130-1 (Microsemi) | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening than JANTX) | Reduced test coverage on parametric limits and lot acceptance; not approved for mission-critical flight hardware | Select only for non-flight prototype builds where cost reduction outweighs qualification rigor |
Compared with JANTX1N4130-1, the 1N4130US trades MIL-qualified reliability for SMT compatibility, while JAN1N4130-1 reduces cost and lead time at the expense of full JANTX screening - making JANTX1N4130-1 the sole choice for production flight hardware requiring documented radiation hardness and lot traceability.

FAQ
What is the Zener voltage tolerance for JANTX1N4130-1?
JANTX1N4130-1 has a nominal Zener voltage of 68 V with ±1% tolerance (D-grade), measured at 250 mA test current and 25 °C ambient. This tight tolerance eliminates need for external trimming in precision reference circuits and is verified per MIL-PRF-19500/435 screening requirements.
Is JANTX1N4130-1 suitable for high-temperature operation?
Yes, JANTX1N4130-1 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 ensures stable performance in avionics and downhole tools where sustained 125 °C ambient is common.
Does JANTX1N4130-1 meet RoHS requirements?
No, JANTX1N4130-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N4130-1e3), not for JANTX-level parts, which retain tin-lead plating to ensure solderability and reliability per MIL-STD-750.
What is the maximum Zener current IZM for JANTX1N4130-1?
The maximum Zener current IZM for JANTX1N4130-1 is 5.6 mA, calculated from its 500 mW power rating and 68 V nominal Zener voltage (P = V × I). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1.
How is polarity marked on JANTX1N4130-1?
JANTX1N4130-1 uses a single black cathode band on the glass body to indicate polarity. The banded end is the cathode and must be held positive relative to the anode for proper Zener regulation - a requirement explicitly stated in the Mechanical and Packaging section of the datasheet.
