Product details
Overview
JANTXV1N4130D-1 from Microsemi is a 500 mW, 68 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4130D-1 datasheet, JANTXV1N4130D-1 pinout, JANTXV1N4130D-1 application, or JANTXV1N4130D-1 equivalent, key selection factors include its 68 V nominal Zener voltage at 250 mA test current, 700 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 51.7 V, +0.100 %/°C temperature coefficient, and hermetically sealed axial-leaded construction.
Technical Context
This device operates as a precision shunt voltage regulator with a sharp breakdown knee (IZK = 250 mA), low noise density (1 µV/√Hz typical at 68 V), and minimal capacitance (<1 pF per Figure 3). Its metallurgical bond ensures stable long-term Zener voltage under thermal cycling and radiation exposure.
Designed for operation in the 250 mA Zener test current regime, it delivers regulated output across wide current ranges (up to 51.7 mA IZM) while maintaining ±1% initial tolerance and predictable temperature drift (+0.100 %/°C), enabling use in reference circuits where stability over -65°C to +175°C is required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4130US-1 | Same 68 V, 1% spec, but in surface-mount DO-213AA package; no axial leads | Used where board space is constrained and reflow assembly is required | Select for automated SMT production; not drop-in compatible due to different footprint and thermal path |
| JANS1N4130D-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500 level) with full radiation testing | Required for mission-critical spaceflight electronics with TID > 300 krad(Si) | Select when full JANS certification, including neutron irradiation and burn-in, is mandated by program requirements |
Compared with JANTXV1N4130D-1, the 1N4130US-1 offers SMT compatibility at the cost of reduced thermal dissipation capability, while JANS1N4130D-1 adds radiation survivability and extended screening - both require explicit validation for the target application's environmental and reliability profile.

FAQ
What is the Zener voltage tolerance of JANTXV1N4130D-1?
JANTXV1N4130D-1 has a ±1% Zener voltage tolerance at 25°C, as indicated by the "D" suffix in its nomenclature per Microsemi's part numbering system. This tight tolerance is maintained across the full operating temperature range (-65°C to +175°C) and supports high-accuracy reference applications without trimming or calibration.
Is JANTXV1N4130D-1 RoHS compliant?
No, JANTXV1N4130D-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4130D-1e3); military-qualified variants like JANTXV1N4130D-1 retain tin-lead plating per MIL-STD-750 to ensure solderability and reliability under thermal cycling in high-reliability applications.
What is the maximum Zener current for JANTXV1N4130D-1?
The maximum Zener current (IZM) for JANTXV1N4130D-1 is 51.7 mA at 25°C, derived from its 500 mW power rating and 68 V nominal Zener voltage. This value decreases linearly with increasing lead temperature, reaching zero at 175°C per the derating curve in Microsemi's T4-LDS-0245-2 datasheet.
Does JANTXV1N4130D-1 have radiation hardness specifications?
Yes, JANTXV1N4130D-1 is inherently radiation-hardened as documented in Microsemi MicroNote 050. It exhibits robust performance under total ionizing dose (TID) conditions up to 100 krad(Si), making it suitable for low-earth orbit satellite subsystems and nuclear instrumentation applications without additional shielding.
What is the thermal resistance junction-to-lead for JANTXV1N4130D-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4130D-1 is 250°C/W when measured with 3/8 inch (10 mm) lead length from the body, per the Maximum Ratings table in T4-LDS-0245-2. This value assumes standard FR4 PCB mounting with 4 mm² copper pads and is critical for calculating junction temperature rise under continuous DC operation.
