Overview
JANTXV1N4124C-1/TR from Microsemi is a 43 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4124C-1/TR datasheet, JANTXV1N4124C-1/TR pinout, JANTXV1N4124C-1/TR application, or JANTXV1N4124C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (≤1 µV/√Hz), temperature coefficient (+0.095 %/°C), and JANTXV-level qualification for extended temperature operation (-65 °C to +175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 43.0 V at 250 mA test current, exhibiting low dynamic impedance (250 Ω) and minimal reverse leakage (≤0.01 µA at 32.7 V). Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, the JANTXV1N4124C-1/TR maintains regulation under thermal stress with junction-to-lead thermal resistance of 250 °C/W and full-rated power dissipation up to 50 °C ambient before linear derating begins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4124US-1 | Same 43 V/2% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping | Select when automated assembly and board space constraints outweigh lead-forming flexibility |
| JANTXV1N4124-1 | Identical electrical specs but ±5% Zener tolerance instead of ±2% | Higher voltage uncertainty impacts closed-loop accuracy in precision feedback paths | Acceptable for non-critical biasing where cost sensitivity outweighs regulation tightness |
Compared with JANTXV1N4124C-1/TR, the 1N4124US-1 offers identical regulation performance in a compact SMT form factor but eliminates axial mounting capability, while JANTXV1N4124-1 trades ±2% tolerance for broader availability and lower unit cost at the expense of reference accuracy in metrology-critical designs.

FAQ
What is the Zener voltage tolerance of JANTXV1N4124C-1/TR?
JANTXV1N4124C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This tighter tolerance enables higher-accuracy voltage references compared to standard ±5% variants like JANTXV1N4124-1, making it suitable for precision feedback loops in regulated power supplies and analog instrumentation circuits where regulation stability is critical.
Is JANTXV1N4124C-1/TR qualified to JANTXV reliability level?
Yes, JANTXV1N4124C-1/TR is fully qualified to the JANTXV level per MIL-PRF-19500/435. This includes rigorous screening for burn-in, temperature cycling, and life testing, ensuring suitability for high-reliability applications such as aerospace avionics and military communications equipment operating across -65 °C to +175 °C junction temperatures.
What is the maximum Zener current IZM for JANTXV1N4124C-1/TR?
The maximum Zener current IZM for JANTXV1N4124C-1/TR is 32.7 mA at 25 °C, calculated from its 500 mW power rating and 43 V nominal Zener voltage. This value assumes thermal equilibrium and must be derated linearly above 50 °C ambient temperature to maintain safe junction operation within the -65 °C to +175 °C range.
Does JANTXV1N4124C-1/TR have low noise characteristics?
Yes, JANTXV1N4124C-1/TR exhibits low noise density of ≤1 µV/√Hz at its 250 mA test current, verified per Microsemi's characterization methodology using a 1 kHz–3 kHz bandpass filter. This makes it appropriate for low-noise voltage reference applications in precision analog signal chains, including sensor biasing and calibration subsystems where spectral purity is essential.
What package type does JANTXV1N4124C-1/TR use?
JANTXV1N4124C-1/TR uses the DO-35 (DO-204AH) axial-leaded, hermetically sealed glass package. The cathode is marked by a band on the glass body, and the device must be operated with the banded end positive relative to the anode to achieve Zener regulation. This package supports manual or wave soldering and provides robust hermeticity for long-term reliability in harsh environments.
