Product details
Overview
JANTXV1N4615D-1/TR from Microsemi is a 1% tolerance, 2.0 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4615D-1/TR datasheet, JANTXV1N4615D-1/TR pinout, JANTXV1N4615D-1/TR application, or JANTXV1N4615D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, noise density, dynamic impedance, and military qualification status - all critical for precision reference and radiation-hardened design validation.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse bias (banded end positive) for Zener regulation. It features an internal metallurgical bond for enhanced thermal stability and low-noise performance, with noise density specified at 1 µV/√Hz at 2.0 V.
Its 1% voltage tolerance (denoted by "D" in part nomenclature), -0.075 %/°C temperature coefficient, and 1250 Ω dynamic impedance at 250 mA test current define its precision and stability envelope across temperature and load variations in regulated power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.0 V ±1% at 250 mA - enables tight-tolerance reference generation for analog sensing and calibration circuits. |
| Power Dissipation | 500 mW @ TL = 25 °C - supports stable operation in compact, conduction-cooled military PCB layouts. |
| Dynamic Impedance ZZT | 1250 Ω @ IZT = 250 mA - indicates moderate AC impedance, suitable for low-frequency regulation but not ultra-low-noise references. |
| Noise Density | 1 µV/√Hz @ 2.0 V - lowest noise in the 1N4614–1N4627 family, critical for precision instrumentation front-ends. |
| Temp Coefficient αVZ | -0.075 %/°C - predictable negative drift allows compensation in temperature-critical bias networks. |
| Reverse Leakage IR | 2.5 µA @ VR = 1.0 V - ensures minimal quiescent current draw in standby or low-power hold-up circuits. |
| Package | DO-35 (DO-204AH) axial-glass - hermetically sealed, MIL-qualified mechanical form factor for harsh-environment mounting. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte tin plated, solderable per MIL-STD-750 method 2026. Weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; establishes reference potential for regulated output. |
| Cathode (banded end) | Zener regulation terminal | Applied positive voltage relative to anode to enter breakdown; delivers stable 2.0 V reference. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Validated reliability for aerospace flight hardware and defense electronics with full lot traceability and screening. |
| 1% Zener voltage tolerance | Reduces calibration overhead in precision analog signal chains and sensor excitation circuits. |
| Metallurgical bond construction | Improves thermal coupling between junction and leads, lowering thermal resistance (RθJL = 250 °C/W) and enhancing long-term stability. |
| Low noise density (1 µV/√Hz) | Minimizes added noise in high-gain amplifier biasing and precision ADC reference buffers. |
| Hermetic glass sealing | Prevents moisture ingress and parameter drift in extended-life, high-humidity, or vacuum-deployed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4615C-1/TR | 2% Zener tolerance instead of 1%; identical VZ, IZT, and package. | Acceptable where ±20 mV total error budget permits looser initial accuracy. | Select when cost sensitivity outweighs need for tightest calibration margin. |
| 1N4615US-1 | Same electrical specs but in surface-mount DO-213AA package; no MIL qualification. | Used in commercial-grade space-constrained boards where JANTXV screening is unnecessary. | Choose for non-military production where footprint reduction and reflow compatibility are prioritized over radiation hardness. |

FAQ
What is the Zener voltage and tolerance of JANTXV1N4615D-1/TR?
JANTXV1N4615D-1/TR has a nominal Zener voltage of 2.0 V with ±1% tolerance at 250 mA test current. This tolerance is confirmed by the "D" suffix in the part number per Microsemi's nomenclature guide and appears in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. The device maintains this specification under MIL-PRF-19500/435 JANTXV screening conditions.
Is JANTXV1N4615D-1/TR RoHS compliant?
No, JANTXV1N4615D-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under defense procurement waivers.
What is the maximum power dissipation and derating behavior of JANTXV1N4615D-1/TR?
JANTXV1N4615D-1/TR has a rated average power dissipation of 500 mW at lead temperature TL = 25 °C. Power must be linearly derated starting at TL = 50 °C, reaching zero at 175 °C. For ambient conditions on a typical PCB, derating begins at 25 °C per Figure 2 in the datasheet, reflecting its RθJA = 300 °C/W thermal resistance.
Does JANTXV1N4615D-1/TR have radiation hardness certification?
Yes, JANTXV1N4615D-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and JANTXV qualification per MIL-PRF-19500/435 provide proven resilience against total ionizing dose (TID) and single-event effects (SEE), making it suitable for space and nuclear environments.
What does the "TR" suffix indicate in JANTXV1N4615D-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard. This format supports automated SMT placement despite the axial DO-35 package, enabling high-volume assembly while maintaining full JANTXV traceability and screening integrity for each reel.
