Product details
Overview
JANTX1N4615D-1 from Microsemi is a 2.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4615D-1 datasheet, JANTX1N4615D-1 pinout, JANTX1N4615D-1 application, or JANTX1N4615D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), noise density (1 µV/√Hz), thermal resistance (250 °C/W), and military qualification level - all critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. Its metallurgical bond construction ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
It delivers regulated output at 2.0 V ±1% with 250 mA test current (IZT), exhibits 1250 Ω dynamic impedance (ZZT), and maintains low noise density of 1 µV/√Hz - optimized for low-noise analog references rather than high-current shunt regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.0 V ±1% at 250 mA - enables precise low-voltage reference generation with tight tolerance for calibration circuits. |
| Power Dissipation | 500 mW at 25 °C lead temperature - supports stable operation in compact, conduction-cooled military PCB layouts. |
| Dynamic Impedance | 1250 Ω at IZT - indicates moderate regulation stiffness; suitable for low-current biasing, not high-precision feedback loops. |
| Noise Density | 1 µV/√Hz - among lowest in the 1N46xx series, critical for low-noise instrumentation and sensor excitation references. |
| Temp Coefficient | -0.075 %/°C - predictable negative drift allows compensation in temperature-stable reference designs. |
| Reverse Leakage | 2.5 µA at 1.0 V - ensures minimal error contribution in high-impedance reference nodes. |
| Thermal Resistance | 250 °C/W (junction-to-lead) - defines safe derating curve when mounted with 10 mm lead length; zero power at 175 °C. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package. Cathode identified by single black band; banded end must be biased positive for Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher potential; provides stable 2.0 V reference when reverse-biased. |
| Anode (unbanded end) | Reference return / ground reference | Typically tied to system ground or lower-potential rail; completes Zener current path. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for aerospace flight hardware and defense electronics with full lot traceability. |
| 1% Zener voltage tolerance | Reduces need for post-calibration trimming in precision voltage references and ADC/DAC bias networks. |
| Metallurgical bond construction | Ensures long-term parameter stability under thermal cycling and mechanical stress in harsh environments. |
| Low 1 µV/√Hz noise density | Enables use in ultra-low-noise analog front-ends, such as strain gauge bridges and photodiode transimpedance amps. |
| Hermetic glass DO-35 package | Provides immunity to humidity-induced leakage and long-term parameter drift in extended-life systems. |
Applications
| Avionics Power Reference | Satellite Sensor Biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4615D-1 | Higher qualification level (JANTXV vs JANTX); tighter screening, enhanced burn-in, and extended temperature validation. | Required for space-grade or mission-critical avionics where failure risk must be minimized beyond JANTX requirements. | Select when full JANTXV compliance is mandated by program specification or system-level FMEA. |
| 1N4615UR-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads; RoHS-compliant plating. | Used in automated SMT assembly lines where through-hole mounting is incompatible with board density or reflow process. | Choose for high-volume commercial or industrial designs needing same Zener performance in compact footprint. |
Compared with JANTX1N4615D-1, the JANTXV variant adds screening rigor for extreme reliability, while the 1N4615UR-1 replaces axial leads with SMT compatibility - neither is pin-compatible due to differing packages, but both deliver identical 2.0 V ±1% regulation and 1 µV/√Hz noise.

FAQ
What is the Zener voltage and tolerance of JANTX1N4615D-1?
JANTX1N4615D-1 has a nominal Zener voltage of 2.0 V with ±1% tolerance, measured at 250 mA test current (IZT) and 25 °C ambient. This tight tolerance is achieved via post-process sorting and is maintained across its qualified military temperature range (-65 °C to +175 °C).
Is JANTX1N4615D-1 suitable for low-noise applications?
Yes, JANTX1N4615D-1 delivers 1 µV/√Hz noise density - the lowest in the 1N4614–1N4627 series for voltages ≤2.2 V - making it ideal for low-noise analog references in sensor interfaces, precision ADCs, and photodiode biasing circuits.
What does the "D" suffix mean in JANTX1N4615D-1?
The "D" in JANTX1N4615D-1 denotes 1% Zener voltage tolerance per MIL-PRF-19500/435. It follows JEDEC nomenclature where D = ±1%, C = ±2%, and blank = ±5%. This distinguishes it from JANTX1N4615-1 (5%) and JANTX1N4615C-1 (2%).
What is the maximum power dissipation and derating behavior of JANTX1N4615D-1?
JANTX1N4615D-1 is rated for 500 mW at 25 °C lead temperature. Power linearly derates to zero at 175 °C, with full derating beginning at 50 °C per MIL-PRF-19500/435. At 100 °C lead temperature, usable power drops to 250 mW.
How is polarity marked on JANTX1N4615D-1, and how must it be connected?
JANTX1N4615D-1 uses a single black band to mark the cathode terminal. For Zener regulation, the banded (cathode) end must be connected to the higher potential, and the unbanded (anode) end to the lower potential or ground - reverse-bias configuration only.
