Product details
Overview
JANTXV1N4129C-1/TR from Microsemi is a 62 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4129C-1/TR datasheet, JANTXV1N4129C-1/TR pinout, JANTXV1N4129C-1/TR application, or JANTXV1N4129C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for radiation-hardened analog design, voltage reference stability, and high-temperature operation up to +175 °C.
Technical Context
This device operates as a reverse-biased voltage regulator with nominal Zener voltage of 62 V at 250 mA test current, ±2% tolerance (denoted by "C" suffix), and positive temperature coefficient of +0.100 %/°C. Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical) and inherent radiation hardness per Microsemi MicroNote 050.
It exhibits 500 Ω maximum dynamic impedance (ZZT) at IZT = 250 mA, 40 µA maximum reverse leakage (IR) at VR = 47.1 V, and thermal resistance junction-to-lead of 250 °C/W with 10 mm lead length - enabling stable regulation across wide current and temperature ranges in hermetically sealed environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4129US-1 | Same 62 V, 2% spec but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used. |
| JANS1N4129C-1 | Identical electrical specs but qualified to JANS (highest MIL-PRF-19500 level) with extended screening and lot traceability | Required for Class K spaceflight hardware; adds cost and lead time vs. JANTXV | Select only when mission assurance requirements mandate JANS-level qualification. |

FAQ
What is the Zener voltage tolerance of JANTXV1N4129C-1/TR?
JANTXV1N4129C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This means its nominal 62 V Zener voltage falls within 60.76 V to 63.24 V at 250 mA test current and 25 °C ambient, meeting MIL-PRF-19500/435 requirements for JANTXV-level devices.
Is JANTXV1N4129C-1/TR RoHS compliant?
No, JANTXV1N4129C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JAN, JANTX, JANTXV, or JANS qualified parts like JANTXV1N4129C-1/TR.
What does the "TR" suffix mean in JANTXV1N4129C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTXV1N4129C-1/TR is supplied in reels for high-volume manufacturing, with standard quantities defined by Microsemi factory specifications.
What is the maximum reverse leakage current for JANTXV1N4129C-1/TR?
JANTXV1N4129C-1/TR has a maximum reverse leakage current (IR) of 40 µA at VR = 47.1 V, measured at 25 °C. This value reflects the diode's ability to hold off voltage below breakdown while minimizing standby power loss in reference circuits.
Can JANTXV1N4129C-1/TR operate at +175 °C junction temperature?
Yes, JANTXV1N4129C-1/TR is rated for junction and storage temperatures from –65 °C to +175 °C. Its 500 mW power dissipation is linearly derated to zero at +175 °C, allowing full-rated operation up to +125 °C ambient when mounted with proper thermal management per MIL-PRF-19500/435 test conditions.
