Product details
Overview
JANTXV1N4615D-1 from Microsemi is a 2.0 V, 1% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, metallurgically bonded for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4615D-1 datasheet, JANTXV1N4615D-1 pinout, JANTXV1N4615D-1 application, or JANTXV1N4615D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, -0.075 %/°C temperature coefficient, 1250 Ω dynamic impedance at 250 mA test current, and MIL-PRF-19500/435 JANTXV qualification for extended temperature operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.0 V at 250 mA test current (IZT), exhibiting low noise density (1 µV/√Hz) and stable regulation across -65 °C to +175 °C junction temperature range.
Its metallurgical bond construction ensures hermetic sealing and radiation hardness per Microsemi MicroNote 050, while the DO-35 axial-glass package supports flexible through-hole mounting and meets MIL-STD-750 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.0 V ±1% at 250 mA - enables precise low-voltage reference in analog sensing and biasing circuits. |
| Power Dissipation | 500 mW at 25 °C - supports stable regulation in compact, unheatsinked designs with linear derating to zero at 175 °C. |
| Dynamic Impedance (ZZT) | 1250 Ω at IZT - defines output impedance under regulation, critical for ripple rejection in low-current references. |
| Temperature Coefficient (αVZ) | -0.075 %/°C - indicates predictable, negative drift over temperature, simplifying compensation in wide-range environments. |
| Noise Density (ND) | 1 µV/√Hz - ultra-low broadband noise ideal for precision instrumentation and low-noise analog front-ends. |
| Reverse Leakage (IR) | 2.5 µA at 1.0 V - minimal standby current ensures low-power operation in battery-backed or always-on systems. |
| Junction Temp Range | -65 °C to +175 °C - qualified for extreme-environment applications including avionics, downhole tools, and space-grade electronics. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point; establishes reference for regulated output. |
| Cathode | Zener regulation terminal | Banded end; connected to input supply; maintains 2.0 V drop across diode when reverse-biased above breakdown. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Guarantees screening, testing, and traceability for defense and aerospace programs requiring high reliability. |
| Metallurgical bond construction | Eliminates epoxy interfaces, improving thermal stability, long-term parameter retention, and resistance to thermal cycling fatigue. |
| 1% Zener voltage tolerance | Reduces need for post-production trimming in precision reference circuits, lowering calibration cost and time. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4615US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for PCB space-constrained or reflow-only assembly environments. | Select when board-level automation or reduced profile is mandatory; not pin-compatible with axial DO-35 footprint. |
| 1N4615UR-1 | Identical Zener parameters and DO-35 package, but only qualified to JANTX level (not JANTXV); lower screening rigor. | Suitable for non-critical military subsystems where full JANTXV burn-in and lot traceability are not mandated. | Choose for cost-sensitive programs accepting reduced reliability assurance; same mechanical fit and electrical behavior. |
Compared with JANTXV1N4615D-1, the JANTXV1N4615US-1 offers identical regulation performance in a surface-mount form factor, while the 1N4615UR-1 provides equivalent electrical function with less stringent qualification-enabling trade-offs between reliability assurance, assembly method, and program cost.

FAQ
What is the Zener voltage tolerance of JANTXV1N4615D-1 and how is it marked?
JANTXV1N4615D-1 has a 1% Zener voltage tolerance, indicated by the "D" suffix in its part number per Microsemi's nomenclature. This corresponds to ±1% deviation from the nominal 2.0 V Zener voltage at 250 mA test current, verified during MIL-PRF-19500/435 JANTXV screening.
Does JANTXV1N4615D-1 meet MIL-STD-750 for solderability and ESD robustness?
Yes, JANTXV1N4615D-1 is solderable per MIL-STD-750 Method 2026 and is non-sensitive to ESD per MIL-STD-750 Method 1020. Its tin-lead or RoHS-compliant matte-tin plating ensures reliable wetting during wave or hand soldering up to 260 °C for 10 seconds.
What is the maximum junction temperature and thermal resistance of JANTXV1N4615D-1?
JANTXV1N4615D-1 has a junction temperature range of -65 °C to +175 °C and a thermal resistance of 250 °C/W junction-to-lead (RθJL) with 3/8″ lead length. Its 500 mW power rating linearly derates to zero at 175 °C ambient on a typical FR4 board.
How does the temperature coefficient of JANTXV1N4615D-1 affect its regulation accuracy?
JANTXV1N4615D-1 has a temperature coefficient (αVZ) of -0.075 %/°C, meaning its Zener voltage decreases by 1.5 mV per 10 °C rise from 25 °C. This predictable negative drift allows designers to compensate reference circuits in wide-temperature applications using simple resistor networks.
Is JANTXV1N4615D-1 suitable for low-noise analog applications?
Yes, JANTXV1N4615D-1 delivers 1 µV/√Hz noise density at 250 mA, among the lowest in its voltage class. This ultra-low noise performance makes it suitable for precision analog front-ends, sensor excitation, and reference generation where signal integrity is critical.
