Product details
Overview
JANTXV1N4617D-1 from Microsemi is a 500 mW, 1% tolerance, 2.4 V Zener diode in DO-35 glass package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation. It delivers stable reference voltage across wide current and temperature ranges, with 1400 Ω dynamic impedance at 250 mA test current and -0.075 %/°C temperature coefficient - used in precision analog power supplies and military-grade instrumentation.
For engineers reviewing the JANTXV1N4617D-1 datasheet, JANTXV1N4617D-1 pinout, JANTXV1N4617D-1 application, or JANTXV1N4617D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, hermetic DO-35 package, JANTXV reliability qualification, low noise density (1 µV/√Hz), and metallurgically bonded construction for radiation-hardened operation.
Technical Context
This device operates as a reverse-biased voltage reference diode with a nominal Zener voltage of 2.4 V at 250 mA test current. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, while its -0.075 %/°C temperature coefficient enables predictable drift compensation in regulated power rails.
The JANTXV1N4617D-1 exhibits 1400 Ω dynamic impedance at IZT = 250 mA and maximum reverse leakage of 1.0 µA at VR = 1.0 V. Its noise density is specified at 1 µV/√Hz - among the lowest in the 1N4614–1N4627 series - making it suitable for low-noise analog references where signal integrity is critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4617US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Used where board space is constrained and reflow assembly required; not suitable for through-hole prototyping. | Select JANTXV1N4617US-1 only when DO-35 leaded mounting is incompatible with layout or assembly process. |
| 1N4617UR-1 | Commercial-grade (non-mil-qualified), same 2.4 V/1% specs, RoHS-compliant matte-tin plating. | Approved for industrial automation and telecom infrastructure; lacks JANTXV screening and radiation data. | Choose 1N4617UR-1 for cost-sensitive, non-safety-critical applications where mil-spec testing is unnecessary. |
Compared with JANTXV1N4617D-1, JANTXV1N4617US-1 offers identical regulation performance in SMT form factor but sacrifices axial-lead serviceability, while 1N4617UR-1 reduces cost and lead time at the expense of radiation hardness and extended temperature validation.

FAQ
What is the Zener voltage tolerance for JANTXV1N4617D-1?
JANTXV1N4617D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where VZ = 2.4 V at IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration overhead in precision analog circuits compared to standard 5% variants like JANTXV1N4617-1.
Is JANTXV1N4617D-1 suitable for high-temperature operation?
Yes, JANTXV1N4617D-1 is rated for junction temperatures from -65 °C to +175 °C, as specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2. Its metallurgically bonded construction and hermetic DO-35 package maintain parameter stability at elevated temperatures, making it appropriate for downhole, engine-control, and avionics applications where ambient temperatures exceed 125 °C.
Does JANTXV1N4617D-1 have radiation hardness documentation?
Yes, JANTXV1N4617D-1 is inherently radiation hard as described in Microsemi MicroNote 050, referenced in the Applications/Benefits section on page 1 of T4-LDS-0245-2. While the datasheet does not list quantitative TID or SEE thresholds, MicroNote 050 confirms the device retains regulation functionality after exposure to total ionizing dose levels typical of low-earth orbit and nuclear instrumentation environments.
What is the noise performance of JANTXV1N4617D-1?
JANTXV1N4617D-1 has a maximum noise density of 1 µV/√Hz at 250 mA test current, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value applies to the 2.4 V variant and is among the lowest in the 1N4614–1N4627 family - significantly lower than higher-voltage parts (e.g., 40 µV/√Hz at 6.8 V), making it optimal for low-noise analog references.
How is polarity marked on JANTXV1N4617D-1?
JANTXV1N4617D-1 uses a cathode band for polarity identification, as stated in the Mechanical and Packaging section on page 2 of T4-LDS-0245-2. The banded end is the cathode and must be biased positive relative to the anode for Zener regulation. This marking is consistent across all DO-35 packaged devices in the 1N4614–1N4627 series and is visible as a single dark ring near one lead end.
