Product details
Overview
JANTXV1N4617D-1/TR from Microsemi is a 2.4 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4617D-1/TR datasheet, JANTXV1N4617D-1/TR pinout, JANTXV1N4617D-1/TR application, or JANTXV1N4617D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), temperature coefficient (−0.075 %/°C), and military-grade qualification level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.4 V at 250 mA test current, exhibiting low dynamic impedance (1400 Ω) and minimal reverse leakage (1.0 µA at 1.0 V). Its metallurgical bond construction ensures stable performance under thermal cycling and mechanical stress.
Designed for operation in the breakdown region, it delivers regulated output across wide current ranges (IZK to IZM = 95 mA) while maintaining low noise density and predictable temperature drift-critical for reference circuits in analog signal chains and power management subsystems.
Key Specifications

|---|---|
| Zener Voltage VZ | 2.4 V ±1% at 250 mA - enables precise low-voltage reference generation with tight tolerance control. |
| Power Dissipation | 500 mW @ 25 °C - supports stable regulation in compact axial-leaded designs without forced cooling. |
| Zener Impedance ZZT | 1400 Ω max - limits output voltage variation under load transients in feedback or bias networks. |
| Noise Density | 1 µV/√Hz - ensures minimal added noise in precision analog references and sensor excitation circuits. |
| Temp Coefficient αVZ | −0.075 %/°C - provides predictable, linear drift for compensated reference designs over −65 to +175 °C. |
| Reverse Leakage IR | 1.0 µA @ 1.0 V - guarantees low standby current in always-on regulation paths. |
| Max Regulator Current IZM | 95 mA - defines safe continuous operating current before thermal derating begins at 50 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4617US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Used where board space is constrained and reflow assembly is required instead of through-hole mounting. | Select when transitioning from through-hole to SMT production or when vibration resistance demands solder-joint geometry optimization. |
| JANTXV1N4617-1 | Identical DO-35 package and electrical parameters, but with ±5% Zener tolerance instead of ±1%. | Applicable in non-critical biasing where tighter tolerance adds unnecessary cost. | Choose for cost-sensitive legacy designs where 5% tolerance meets system accuracy requirements. |
Compared with JANTXV1N4617D-1/TR, the 1N4617US-1 offers identical regulation performance in a surface-mount form factor, while JANTXV1N4617-1 trades 1% tolerance for lower unit cost-enabling design flexibility across reliability, precision, and manufacturability axes.

FAQ
What is the Zener voltage tolerance of JANTXV1N4617D-1/TR?
JANTXV1N4617D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This corresponds to a nominal 2.4 V Zener voltage ranging from 2.376 V to 2.424 V at 250 mA test current and 25 °C ambient, enabling high-accuracy reference design without external trimming.
Is JANTXV1N4617D-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTXV1N4617D-1/TR is qualified to the JANTXV level per MIL-PRF-19500/435, as confirmed in Microsemi's T4-LDS-0245-2 datasheet. This qualification includes rigorous screening for temperature cycling, mechanical shock, vibration, and long-term life testing-making JANTXV1N4617D-1/TR suitable for mission-critical aerospace and defense systems.
What is the maximum Zener current rating for JANTXV1N4617D-1/TR?
The maximum Zener current (IZM) for JANTXV1N4617D-1/TR is 95 mA at 25 °C lead temperature, derived from its 500 mW power rating and 2.4 V Zener voltage. Above 50 °C, power must be linearly derated to zero at 175 °C, limiting usable IZM in high-temperature environments unless heatsinking is applied.
Does JANTXV1N4617D-1/TR have low-noise characteristics?
Yes, JANTXV1N4617D-1/TR exhibits a noise density of 1 µV/√Hz at 250 mA test current, as specified in the Electrical Characteristics table. This low noise performance is critical for use in precision analog circuits such as ADC references, sensor excitation, and low-jitter oscillator bias networks where added noise degrades signal fidelity.
What package type does JANTXV1N4617D-1/TR use?
JANTXV1N4617D-1/TR uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, with cathode identified by a band. The package dimensions comply with JEDEC standards, and the "TR" suffix indicates tape-and-reel packaging per EIA-296 for automated assembly-ensuring consistent handling and placement of JANTXV1N4617D-1/TR in high-reliability production lines.
