Product details
Overview
JANTXV1N4127C-1 from Microsemi is a 500 mW, 56 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 JANTXV1N4127C-1 datasheet, JANTXV1N4127C-1 pinout, JANTXV1N4127C-1 application, or JANTXV1N4127C-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 56 V at 250 mA test current, exhibiting a temperature coefficient of +0.100 %/°C and dynamic impedance of 300 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, JANTXV1N4127C-1 maintains regulation across wide current ranges (IZK to IZM = 42.6 mA max) and ambient temperatures (–65 °C to +175 °C), with minimal capacitance (<1 pF typical at 56 V) and ESD immunity per MIL-STD-750 method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4127C-1 | JANS-level qualification (higher screen severity than JANTXV); identical electrical specs and DO-35 package | Required for Class S spaceflight hardware; adds burn-in, lot acceptance tests, and radiation lot acceptance testing | Select JANS1N4127C-1 only when full MIL-PRF-19500/435 Class S compliance is mandated |
| 1N4127C-1 (commercial) | No MIL qualification; RoHS-compliant plating available; same VZ, ZZT, ND, and package | Limited to non-safety-critical industrial or test equipment; not suitable for flight or mission-critical systems | Choose 1N4127C-1 for cost-sensitive prototyping or commercial-grade instrumentation where MIL screening is unnecessary |
Compared with JANS1N4127C-1, JANTXV1N4127C-1 offers reduced test overhead and faster lead time while retaining full JANTXV reliability for airborne platforms; versus commercial 1N4127C-1, it delivers verified parametric stability and traceable screening essential for field-deployed defense electronics.

FAQ
What is the Zener voltage tolerance of JANTXV1N4127C-1?
JANTXV1N4127C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its measured VZ at 250 mA test current falls within 54.88 V to 57.12 V at 25 °C, enabling tighter regulation than standard ±5% variants in critical reference designs.
Is JANTXV1N4127C-1 suitable for high-radiation environments?
Yes, JANTXV1N4127C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide proven tolerance to total ionizing dose (TID), making JANTXV1N4127C-1 appropriate for satellite, nuclear, and high-altitude avionics applications without additional shielding.
What is the maximum Zener current IZM for JANTXV1N4127C-1?
The maximum Zener current IZM for JANTXV1N4127C-1 is 42.6 mA, derived from its 500 mW power rating and 56 V nominal Zener voltage (P = V × I). Exceeding this current risks thermal runaway unless board-level thermal management (e.g., copper pour, lead length) is optimized per the 250 °C/W junction-to-lead resistance spec.
Does JANTXV1N4127C-1 have RoHS compliance?
No, JANTXV1N4127C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant plating (e3 suffix) is available only on commercial-grade versions (e.g., 1N4127C-1e3); JANTXV-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability assemblies.
How does the temperature coefficient affect JANTXV1N4127C-1 in wide-temperature applications?
JANTXV1N4127C-1 has a temperature coefficient αVZ of +0.100 %/°C, meaning its Zener voltage increases by approximately 56 mV per °C rise above 25 °C. Over a –55 °C to +125 °C range, this results in ~+8.4 V total shift, which must be compensated in precision references via external circuitry or calibration - a known design constraint addressed in Microsemi app notes.
