Product details
Overview
JANTX1N4617D-1 from Microsemi is a 1% tolerance, 2.4 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4617D-1 datasheet, JANTX1N4617D-1 pinout, JANTX1N4617D-1 application, or JANTX1N4617D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and MIL-spec qualification level - all critical for precision biasing and low-noise reference design.
Technical Context
This device operates as a reverse-biased Zener regulator with a nominal 2.4 V breakdown at 250 mA test current, exhibiting a temperature coefficient of –0.075 %/°C and dynamic impedance of 1400 Ω at IZT. Its metallurgical bond ensures stable long-term voltage regulation under thermal cycling.
Designed for hermetic axial-leaded mounting, it delivers low capacitance (typical <2 pF per Figure 3) and ESD immunity per MIL-STD-750 Method 1020, making it suitable for analog front-end references where leakage (<1 µA at VR = 1.0 V) and noise performance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.4 V ±1% at 250 mA - enables precise low-voltage reference generation with tight initial accuracy. |
| Power Dissipation | 500 mW at 25 °C lead temperature - supports stable operation in compact, conduction-cooled designs. |
| Noise Density | 1 µV/√Hz at 25 °C - minimizes voltage reference noise in sensitive analog circuits like ADC bias rails. |
| Dynamic Impedance ZZT | 1400 Ω at 250 mA - defines regulation stiffness; lower values improve load transient response. |
| Reverse Leakage IR | ≤1 µA at 1.0 V - ensures negligible current draw in standby or high-impedance sensing nodes. |
| Temp Coefficient αVZ | –0.075 %/°C - predicts predictable, linear drift over –65 to +175 °C operating range. |
| Junction Temp Range | –65 to +175 °C - validated for extreme-environment applications including space-grade power conditioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4617D-1 | Higher screening level (JANTXV vs JANTX); tighter parametric limits on ZZT and IR. | Required for systems demanding extended burn-in and radiation hardness validation beyond JANTX. | Select when full JANTXV compliance per MIL-PRF-19500/435 is mandated for mission-critical subsystems. |
| 1N4617UR-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Used in automated SMT assembly lines where through-hole insertion is not supported. | Choose for PCB space-constrained or high-volume production designs requiring reflow compatibility. |
Compared with JANTX1N4617D-1, JANTXV1N4617D-1 offers enhanced screening for higher assurance environments, while 1N4617UR-1 provides identical regulation performance in a surface-mount form factor - neither is pin-compatible due to differing packages, and both require layout adaptation.

FAQ
What is the Zener voltage tolerance for JANTX1N4617D-1?
JANTX1N4617D-1 has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where VZ = 2.4 V @ IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration overhead in precision reference designs compared to standard 5% variants like JANTX1N4617-1.
Is JANTX1N4617D-1 qualified to MIL-PRF-19500/435?
Yes, JANTX1N4617D-1 is qualified to MIL-PRF-19500/435 at the JANTX reliability level, as stated in the DESCRIPTION section on page 1 of T4-LDS-0245-2 Rev. 1. This includes screening for temperature cycling, mechanical shock, and long-term life testing - essential for deployment in defense and space platforms where field failure is unacceptable.
What is the maximum Zener current IZM for JANTX1N4617D-1?
The maximum Zener current IZM for JANTX1N4617D-1 is 95.0 mA, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value corresponds to the 500 mW power rating derated at 25 °C lead temperature and ensures safe continuous operation without exceeding thermal limits in properly heatsinked axial-lead configurations.
Does JANTX1N4617D-1 have low noise performance?
Yes, JANTX1N4617D-1 exhibits a maximum noise density of 1 µV/√Hz at 25 °C, as specified in the Electrical Characteristics table. This low noise is achieved via metallurgical bonding and optimized junction design, making JANTX1N4617D-1 suitable for high-fidelity analog references where noise contributes directly to system error budget.
What package type does JANTX1N4617D-1 use?
JANTX1N4617D-1 uses the DO-35 (DO-204AH) axial-leaded hermetically sealed glass package, as confirmed in the MECHANICAL and PACKAGING section on page 2 of T4-LDS-0245-2 Rev. 1. Dimensions are fully specified on page 5, with body diameter 1.42–2.29 mm and overall length 25.4–38.1 mm - standard for through-hole military-grade Zener diodes.
