Product details
Overview
JANTXV1N4125C-1 from Microsemi is a 500 mW, 47 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 JANTXV1N4125C-1 datasheet, JANTXV1N4125C-1 pinout, JANTXV1N4125C-1 application, or JANTXV1N4125C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 μV/√Hz), radiation hardness, and hermetic DO-35 packaging for stable operation across -65°C to +175°C.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 47 V at 250 mA test current, exhibiting a temperature coefficient of +0.095 %/°C and dynamic impedance of 250 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for high-reliability environments, JANTXV1N4125C-1 maintains regulation over wide current ranges (IZK to IZM = 35.8 mA max) and delivers low reverse leakage (≤10 nA at VR = 37.6 V), with minimal capacitance (<1.5 pF typical) critical for noise-sensitive analog reference circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4125C-1 | Same electrical specs; qualified to higher JANS level with extended screening and lot traceability | Required for Class S spaceflight hardware where full JANS compliance is mandated | Select JANS1N4125C-1 only when JANS-level documentation, radiation test reports, and lot-specific certificates are contractually required |
| 1N4125UR-1 | Same 47 V ±2% Zener voltage but in DO-213AA surface-mount package; no MIL-qualification | Suitable for commercial or industrial PCBs where automated assembly and board space constrain axial leads | Choose 1N4125UR-1 for cost-sensitive, non-mil applications needing same regulation performance in SMT format |
Compared with JANTXV1N4125C-1, JANS1N4125C-1 adds full space-level screening and traceability at higher cost and longer lead time, while 1N4125UR-1 trades military qualification for SMT compatibility and commercial pricing-neither is pin-compatible due to differing packages.

FAQ
What is the Zener voltage tolerance for JANTXV1N4125C-1?
JANTXV1N4125C-1 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a nominal 47 V Zener voltage ranging from 46.06 V to 47.94 V at 250 mA test current and 25°C ambient, verified per MIL-PRF-19500/435 screening requirements.
Is JANTXV1N4125C-1 radiation hardened?
Yes, JANTXV1N4125C-1 is inherently radiation hard per Microsemi MicroNote 050, due to its metallurgically bonded structure and hermetic DO-35 packaging. It exhibits robust total ionizing dose (TID) tolerance suitable for low-earth orbit and avionics applications, though specific TID test data requires consulting Microchip's qualified manufacturer list (QML) documentation for JANTXV-level parts.
What is the maximum Zener current IZM for JANTXV1N4125C-1?
The maximum Zener current IZM for JANTXV1N4125C-1 is 35.8 mA, derived from its 500 mW power rating and 47 V nominal Zener voltage (IZM = PM(AV)/VZ ≈ 0.5 W / 47 V). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, and assumes operation at 25°C with appropriate thermal management.
Does JANTXV1N4125C-1 have RoHS compliance?
No, JANTXV1N4125C-1 is not RoHS compliant. Per the Microsemi datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the thermal resistance junction-to-lead for JANTXV1N4125C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4125C-1 is 250°C/W, measured with 3/8 inch (10 mm) lead length from the package body. This value is specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1 and informs heatsinking design when operating near maximum power dissipation.
