Product details
Overview
JANTXV1N4618C-1 from Microsemi is a 2.7 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 1500 Ω dynamic impedance at 250 mA test current, and 0.5 µA maximum reverse leakage at 2.0 V. It serves as a precision voltage reference in military-grade power regulation and analog signal conditioning circuits.
For engineers reviewing the JANTXV1N4618C-1 datasheet, JANTXV1N4618C-1 pinout, JANTXV1N4618C-1 application, or JANTXV1N4618C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), MIL-spec reliability qualification, thermal resistance (250 °C/W junction-to-lead), and axial-leaded DO-35 mechanical compatibility.
Technical Context
This device operates in reverse breakdown mode with cathode band indicating polarity, requiring banded end to be held positive relative to anode for regulation. Its metallurgical bond construction ensures stable Zener voltage over temperature and radiation exposure, supporting operation from –65 °C to +175 °C.
The 2.7 V nominal Zener voltage exhibits a temperature coefficient of –0.075 %/°C, enabling predictable drift compensation in high-reliability analog references. Power dissipation is linearly derated from 500 mW at 25 °C ambient to zero at 175 °C, with junction-to-lead thermal resistance of 250 °C/W measured at 3/8″ lead length.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 2.7 V ±2% at 250 mA - defines precise regulation point for low-voltage reference design |
| Power Dissipation | 500 mW max at 25 °C - sets absolute thermal limit before derating begins at 50 °C |
| Dynamic Impedance (ZZT) | 1500 Ω at IZT = 250 mA - determines output voltage stability under load variation |
| Reverse Leakage (IR) | 0.5 µA max at VR = 2.0 V - ensures minimal error current in high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4618-1 | Same 2.7 V nominal Zener voltage but ±5% tolerance (no C suffix) | Acceptable where calibration or trimming compensates for wider initial tolerance | Select when cost sensitivity outweighs need for tighter initial accuracy |
| 1N4618UR-1 | Surface-mount DO-213AA package; identical electrical specs except RoHS-compliant plating | Required for automated SMT assembly; lacks axial-lead mounting flexibility | Select when board space constraints or reflow-only process mandates SMT packaging |
Compared with JANTXV1N4618C-1, JANTXV1N4618-1 trades ±2% initial accuracy for lower cost and broader availability, while 1N4618UR-1 preserves all electrical performance in a surface-mount form factor-neither is pin-compatible due to differing package geometries and terminal configurations.

FAQ
What is the Zener voltage tolerance for JANTXV1N4618C-1?
JANTXV1N4618C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where nominal VZ = 2.7 V at IZT = 250 mA. The tighter tolerance reduces calibration burden in high-accuracy analog systems compared to standard ±5% variants like JANTXV1N4618-1.
Is JANTXV1N4618C-1 qualified to JANTXV reliability level?
Yes, JANTXV1N4618C-1 is explicitly qualified to the JANTXV level per MIL-PRF-19500/435, as stated in the DESCRIPTION section on page 1 of T4-LDS-0245-2 Rev. 1. This includes rigorous screening for vibration, thermal shock, and burn-in, making it suitable for high-reliability military and aerospace applications where failure is not acceptable.
What is the maximum reverse leakage current for JANTXV1N4618C-1?
JANTXV1N4618C-1 has a maximum reverse leakage current (IR) of 0.5 µA at VR = 2.0 V, per the Electrical Characteristics table on page 3. This low leakage ensures minimal error contribution in high-impedance bias networks and precision reference dividers, especially critical in battery-powered or low-power sensor interfaces.
Does JANTXV1N4618C-1 have radiation hardness?
Yes, JANTXV1N4618C-1 is inherently radiation hard, as documented in Microsemi MicroNote 050 referenced on page 1. Its metallurgically bonded glass construction and hermetic sealing provide tolerance to total ionizing dose (TID) without parameter degradation-making it suitable for satellite, nuclear, and downhole electronics where radiation exposure is unavoidable.
What package type does JANTXV1N4618C-1 use?
JANTXV1N4618C-1 uses the DO-35 (DO-204AH) axial-leaded glass package, specified on page 1 and detailed in Package Dimensions on page 5. It features hermetic sealing, tin-lead or RoHS-compliant matte-tin plating, and cathode identification via a color band-enabling through-hole mounting with proven thermal and mechanical reliability in demanding environments.
