Product details
Overview
JANTXV1N4130C-1 from Microsemi is a 500 mW, 68 V, ±2% 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 JANTXV1N4130C-1 datasheet, JANTXV1N4130C-1 pinout, JANTXV1N4130C-1 application, or JANTXV1N4130C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and MIL-spec thermal derating behavior.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 68 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 700 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in the reverse-biased breakdown region, the JANTXV1N4130C-1 delivers regulated voltage across wide current ranges (IZK to IZM = 40 mA to 51.7 mA) while maintaining low leakage (IR ≤ 0.01 µA at VR = 54.4 V) and minimal capacitance (typ. <1.5 pF).
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 ±2% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated assembly and board space constraints outweigh manual serviceability needs |
| JANS1N4130C-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL level) with enhanced screening | Required for mission-critical systems where failure modes demand zero latent defects (e.g., guidance computers) | Select only when JANS certification documentation and extended lot testing are contractually mandated |
Compared with JANTXV1N4130C-1, the 1N4130US-1 offers footprint reduction at the cost of lead-forming flexibility, while JANS1N4130C-1 adds screening rigor without altering regulation performance-making the JANTXV grade optimal for high-reliability programs balancing cost, test depth, and manufacturability.

FAQ
What is the Zener voltage tolerance of JANTXV1N4130C-1?
JANTXV1N4130C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This corresponds to a guaranteed 68 V regulation point ranging from 66.64 V to 69.36 V at 250 mA test current and 25 °C ambient, verified per MIL-PRF-19500/435 screening requirements.
Is JANTXV1N4130C-1 suitable for high-radiation environments?
Yes, JANTXV1N4130C-1 is inherently radiation-hardened as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide proven tolerance to total ionizing dose (TID), making it suitable for use in satellites, nuclear instrumentation, and other high-radiation applications without additional shielding.
What is the maximum Zener current rating for JANTXV1N4130C-1?
The maximum Zener current IZM for JANTXV1N4130C-1 is 51.7 mA at 25 °C, calculated from its 500 mW power rating and 68 V nominal Zener voltage. Derating begins linearly above 50 °C case temperature, reaching zero dissipation at 175 °C per Figure 2 in the official datasheet.
Does JANTXV1N4130C-1 have RoHS compliance?
No, JANTXV1N4130C-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4130C-1e3); JANTXV-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
How is polarity marked on JANTXV1N4130C-1?
JANTXV1N4130C-1 uses a cathode band marking: the banded end is the cathode and must be held at higher potential than the anode to achieve Zener regulation. This marking follows JEDEC DO-35 conventions and is visible on the glass body near one lead termination.
