Product details
Overview
JANTXV1N4102C-1 from Microsemi is a 500 mW, 8.7 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability applications. It delivers stable voltage regulation across wide current and temperature ranges with low dynamic impedance (200 Ω at 250 mA), minimal noise density (1 µV/√Hz), and radiation-hardened construction.
For engineers reviewing the JANTXV1N4102C-1 datasheet, JANTXV1N4102C-1 pinout, JANTXV1N4102C-1 application, or JANTXV1N4102C-1 equivalent, key selection criteria include its 8.7 V nominal Zener voltage, ±2% tolerance, 250 mA test current, 200 Ω dynamic impedance, and JANTXV-level military qualification for aerospace and defense power regulation circuits.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, while hermetic glass encapsulation provides long-term reliability in harsh environments.
Designed for operation at 250 mA Zener test current, it exhibits a +0.075 %/°C temperature coefficient and maintains ≤0.5 µA reverse leakage at 7.0 V, supporting stable reference generation in analog signal chains and power supply feedback loops where low drift and low noise are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair | Select when board space is constrained and reflow compatibility is mandatory |
| JANTXV1N4102D-1 | Identical construction and package, but ±1% Zener tolerance instead of ±2% | Used where tighter initial accuracy is needed, e.g., calibration references or metrology equipment | Choose only if system-level accuracy budget demands sub-0.1 V tolerance at 25 °C |
Compared with JANTXV1N4102C-1, the JANTXV1N4102D-1 offers improved initial accuracy at higher cost and tighter test screening, while the 1N4102US-1 enables PCB miniaturization at the expense of manual handling and thermal resistance trade-offs.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4102C-1?
JANTXV1N4102C-1 has a nominal Zener voltage of 8.7 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet, and applies strictly to the JANTXV reliability level under specified thermal equilibrium conditions.
Is JANTXV1N4102C-1 suitable for space applications?
Yes, JANTXV1N4102C-1 is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to MIL-PRF-19500/435 JANTXV level, making it suitable for low-Earth orbit (LEO) satellite power regulation where total ionizing dose (TID) resistance and hermetic reliability are required.
What is the maximum power dissipation and derating behavior of JANTXV1N4102C-1?
JANTXV1N4102C-1 has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at 175 °C. Derating begins at 50 °C for lead temperature and follows a slope of –6.25 mW/°C, as defined in the Maximum Ratings table on page 1 of the official datasheet.
Does JANTXV1N4102C-1 have low noise performance?
Yes, JANTXV1N4102C-1 exhibits a noise density of 1 µV/√Hz at 250 mA test current, verified in Figure 1 and the Electrical Characteristics table. This ultra-low noise enables direct use in precision analog circuits such as ADC references and sensor signal conditioning without external filtering.
What package type and marking does JANTXV1N4102C-1 use?
JANTXV1N4102C-1 uses the DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by a visible band. The part is marked with its full JEDEC type number "1N4102" and reliability suffix "JANTXV"; RoHS compliance is not applicable as JANTXV grade uses tin-lead plating per MIL-STD-750.
