Product details
Overview
JANTXV1N4123C-1 from Microsemi is a 500 mW, 39.0 V ±2% tolerance Zener diode in DO-35 glass axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4123C-1 datasheet, JANTXV1N4123C-1 pinout, JANTXV1N4123C-1 application, or JANTXV1N4123C-1 equivalent, key selection factors 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 31.2 V, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics under thermal and radiation stress. Its 39.0 V Zener voltage exhibits a +0.095 %/°C temperature coefficient and delivers ≤1 µV/√Hz noise density below 6.8 V-verified at 250 mA IZT.
The DO-35 (DO-204AH) hermetically sealed glass package supports axial-leaded mounting and enables operation up to 175 °C junction temperature, with thermal resistance of 250 °C/W junction-to-lead at 10 mm lead length.
Key Specifications

|---|---|
| Zener Voltage VZ | 39.0 V ±2% at 250 mA - ensures tight regulation in reference circuits requiring stable 39 V output. |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in low-power analog rails without forced cooling. |
| Dynamic Impedance ZZT | 200 Ω max at 250 mA - maintains low output impedance for minimal voltage deviation under load transients. |
| Reverse Leakage IR | 0.01 µA max at 31.2 V - guarantees negligible quiescent current in standby or battery-backed systems. |

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 Zener voltage and JANTXV qualification, but in surface-mount DO-213AA package. | Requires PCB re-layout for SMT assembly; eliminates axial lead insertion and trimming steps. | Select when automated assembly, space constraints, or vibration resistance outweigh axial-mount heritage requirements. |
| JAN1N4123C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTXV). | Approved for non-flight-critical ground support equipment where full JANTXV testing is not mandated. | Select for cost-sensitive programs with relaxed reliability requirements and identical form-factor needs. |
Compared with JANTXV1N4123C-1, the 1N4123US-1 offers identical regulation performance in a compact SMT footprint, while the JAN1N4123C-1 provides matching axial form factor at lower qualification cost-neither is pin-compatible in the sense of drop-in replacement without review of screening documentation and layout compatibility.

FAQ
What is the Zener voltage tolerance of JANTXV1N4123C-1?
JANTXV1N4123C-1 has a nominal Zener voltage of 39.0 V with ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range of -65 °C to +175 °C.
Is JANTXV1N4123C-1 RoHS compliant?
No, JANTXV1N4123C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only on commercial-grade variants-not on JAN, JANTX, JANTXV, or JANS qualified parts like JANTXV1N4123C-1, which retain traditional tin-lead plating for solderability and reliability in high-reliability applications.
What is the maximum reverse leakage current for JANTXV1N4123C-1?
The maximum reverse leakage current (IR) for JANTXV1N4123C-1 is 0.01 µA at VR = 31.2 V (80% of nominal VZ), as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This ultra-low leakage supports high-impedance reference applications without introducing measurable error.
Can JANTXV1N4123C-1 be used in surface-mount designs?
JANTXV1N4123C-1 itself is axial-leaded in DO-35 package and not suitable for direct SMT placement. However, Microsemi offers the functionally equivalent 1N4123US-1 in DO-213AA surface-mount package with identical 39.0 V ±2% Zener voltage and JANTXV qualification-enabling SMT integration without compromising specification compliance.
What is the thermal resistance junction-to-lead for JANTXV1N4123C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4123C-1 is 250 °C/W when measured at 3/8 inch (10 mm) lead length from the body, per the Maximum Ratings table. This value assumes standard mounting on FR4 with 4 mm² copper pads and is critical for calculating safe operating area under sustained power dissipation.
