Product details
Overview
JANTXV1N4123D-1 from Microsemi is a 39.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4123D-1 datasheet, JANTXV1N4123D-1 pinout, JANTXV1N4123D-1 application, or JANTXV1N4123D-1 equivalent, key selection criteria include its 39.0 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 29.7 V, ±1% voltage tolerance, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee at IZK and stable regulation across wide current (250 mA IZT, up to 40 mA IZM) and temperature (-65 °C to +175 °C) ranges. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at lower voltages) and radiation hardness per Microsemi MicroNote 050.
The JANTXV1N4123D-1 exhibits a positive temperature coefficient of +0.095 %/°C and minimal capacitance (typical <2 pF), making it suitable for low-noise reference and stabilization circuits where thermal drift and parasitic coupling must be tightly controlled.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4123US-1 | Same 39.0 V, 1% spec, but in surface-mount DO-213AA package; no axial leads. | Requires PCB redesign for SMT assembly; eliminates through-hole mounting and lead-forming steps. | Select for automated production where board space and reflow compatibility are prioritized over legacy through-hole compatibility. |
| JANS1N4123D-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500 level) with extended screening. | Suitable for radiation-intensive missions (e.g., deep-space probes) where JANTXV is insufficient. | Select when full JANS-level radiation hardness and burn-in are mandated by program requirements. |
Compared with JANTXV1N4123D-1, the 1N4123US-1 offers SMT integration at the cost of mechanical mounting flexibility, while JANS1N4123D-1 delivers enhanced reliability assurance for extreme radiation environments-neither is pin-compatible due to differing package formats or screening scope.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4123D-1?
JANTXV1N4123D-1 has a nominal Zener voltage of 39.0 V at 250 mA test current with a tight ±1% tolerance. This specification is verified per MIL-PRF-19500/435 screening and applies across the full -65 °C to +175 °C junction temperature range, ensuring consistent regulation performance in demanding thermal environments.
What package type does JANTXV1N4123D-1 use and how is polarity marked?
JANTXV1N4123D-1 uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package. Polarity is marked by a visible cathode band on the glass body; the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation operation.
What is the maximum power dissipation and derating behavior of JANTXV1N4123D-1?
JANTXV1N4123D-1 is rated for 500 mW average power dissipation at 25 °C lead temperature. Power must be linearly derated starting at 50 °C, reaching zero at 175 °C. On a typical FR4 board with 4 mm² copper pads, derating begins at 25 °C ambient and follows the same linear slope to maintain safe junction temperatures.
Is JANTXV1N4123D-1 RoHS compliant?
No, JANTXV1N4123D-1 is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4123D-1e3). JANTXV-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the temperature coefficient of JANTXV1N4123D-1 and why does it matter?
JANTXV1N4123D-1 has a temperature coefficient of +0.095 %/°C, meaning its Zener voltage increases by approximately 0.037 V per 10 °C rise in junction temperature. This predictable drift enables accurate thermal compensation in precision reference designs and ensures stable operation across the full military temperature range.
