Product details
Overview
JANTX1N4617C-1 from Microsemi is a 500 mW, 2.4 V Zener diode in DO-35 glass package, qualified to MIL-PRF-19500/435 JANTX level, with ±2% voltage tolerance, 1400 Ω dynamic impedance at 250 mA test current, and 1 µV/√Hz noise density - used for precision voltage reference and regulation in military-grade power supply monitoring circuits.
For engineers reviewing the JANTX1N4617C-1 datasheet, JANTX1N4617C-1 pinout, JANTX1N4617C-1 application, or JANTX1N4617C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and MIL-qualified reliability for high-reliability analog reference design.
Technical Context
This device operates as a reverse-biased voltage regulator with metallurgically bonded construction for stable breakdown characteristics across -65 °C to +175 °C. Its 2.4 V nominal Zener voltage is specified at 250 mA test current (IZT), with temperature coefficient αVZ = -0.075 %/°C and maximum reverse leakage IR = 1.0 µA at VR = 1.0 V.
The DO-35 axial-leaded glass package enables hermetic sealing and low parasitic capacitance, while its 250 °C/W junction-to-lead thermal resistance supports reliable operation under pulsed or continuous DC bias when lead length is maintained at 3/8 inch (10 mm) from body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.4 V ±2% at IZT = 250 mA - defines precise regulation point for low-voltage reference circuits |
| Power Dissipation | 500 mW at TC = 25 °C, linearly derated to zero at 175 °C - sets maximum continuous thermal load on PCB layout |
| Dynamic Impedance ZZT | 1400 Ω at IZT = 250 mA - determines output voltage stability under varying load current |
| Noise Density ND | 1 µV/√Hz at IZT = 250 mA - critical for low-noise analog references and sensor excitation |
| Temp Coefficient αVZ | -0.075 %/°C - quantifies voltage drift over operating temperature range |
| Reverse Leakage IR | 1.0 µA max at VR = 1.0 V - ensures minimal quiescent current in standby regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4617UR-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair | Select when board space is constrained and reflow compatibility is mandatory |
| JANTXV1N4617C-1 | Identical electrical parameters but qualified to JANTXV level with enhanced screening (e.g., extended life test, radiation hardness verification) | Required for spaceflight or nuclear-hardened systems where single-event effects must be mitigated | Select when mission-critical radiation tolerance and extended reliability validation are mandated |
Compared with JANTX1N4617C-1, the 1N4617UR-1 enables SMT scalability but forfeits axial-lead serviceability, while JANTXV1N4617C-1 adds radiation hardening and extended screening at higher cost and longer lead time - choice depends on assembly process and mission assurance tier.

FAQ
What is the Zener voltage tolerance for JANTX1N4617C-1?
JANTX1N4617C-1 has a nominal Zener voltage of 2.4 V with ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full military temperature range when derated per the power curve.
Is JANTX1N4617C-1 RoHS compliant?
No, JANTX1N4617C-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4617C-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under thermal cycling in military applications.
What is the maximum reverse leakage current for JANTX1N4617C-1?
JANTX1N4617C-1 has a maximum reverse leakage current (IR) of 1.0 µA at VR = 1.0 V, measured at 25 °C. This low leakage supports stable regulation in high-impedance bias networks and minimizes standby power loss in battery-backed systems.
Can JANTX1N4617C-1 be used in surface-mount designs?
JANTX1N4617C-1 uses a DO-35 axial-leaded package and is not suitable for direct SMT placement. For surface-mount equivalents, consider the JANTX-qualified 1N4617UR-1 in DO-213AA package - identical electrical specs but designed for reflow soldering and automated assembly.
What is the thermal resistance specification for JANTX1N4617C-1?
JANTX1N4617C-1 has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, per MIL-PRF-19500/435 test conditions. This value guides heatsinking decisions and power derating in high-temperature PCB layouts.
