Product details
Overview
JANTXV1N4618D-1 from Microsemi is a 500 mW, 2.7 V Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 1% 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 JANTXV1N4618D-1 datasheet, JANTXV1N4618D-1 pinout, JANTXV1N4618D-1 application, or JANTXV1N4618D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, JANTXV reliability qualification, DO-35 axial-leaded hermetic packaging, low noise density (1 µV/√Hz), and thermal derating behavior from 500 mW at 25 °C to zero at 175 °C.
Technical Context
This device operates in reverse-biased breakdown mode with a nominal Zener voltage of 2.7 V at 250 mA test current (IZT), exhibiting a temperature coefficient of –0.075 %/°C. Its metallurgically bonded junction ensures stable regulation across wide current (1–90 mA) and temperature (–65 to +175 °C) ranges.
Designed for high-reliability analog references, it delivers low capacitance (<1.5 pF typical), ESD immunity per MIL-STD-750 method 1020, and radiation hardness per Microsemi MicroNote 050 - all validated under JANTXV-level screening including burn-in, temperature cycling, and hermeticity testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4618US-1 | Same electrical specs but in DO-213AA surface-mount package | Requires PCB re-layout for SMT assembly; eliminates axial lead insertion step | Select when automated assembly, space constraints, or vibration resistance outweigh axial mounting flexibility |
| 1N4618UR-1 | Identical Zener parameters but commercial-grade (non-mil-qualified), RoHS-compliant | Lacks JANTXV screening; not approved for defense/aerospace BOMs requiring MIL-PRF-19500 compliance | Select for cost-sensitive industrial prototypes where full mil-spec qualification is unnecessary |
Compared with JANTXV1N4618D-1, the JANTXV1N4618US-1 offers identical regulation performance in a smaller footprint but requires SMT process changes, while the 1N4618UR-1 reduces cost and meets RoHS but forfeits military reliability validation and traceability.

FAQ
What is the Zener voltage tolerance for JANTXV1N4618D-1?
JANTXV1N4618D-1 has a nominal Zener voltage of 2.7 V with a tight ±1% tolerance, denoted by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range of –65 to +175 °C and is verified during JANTXV-level qualification testing, making JANTXV1N4618D-1 suitable for applications demanding high initial accuracy without post-manufacturing calibration.
Does JANTXV1N4618D-1 meet MIL-PRF-19500/435 requirements?
Yes, JANTXV1N4618D-1 is fully qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including rigorous screening such as steady-state life test, temperature cycling, mechanical shock, and hermeticity verification. The "JANTXV" prefix explicitly confirms compliance, and full test data is available in Microsemi's QPL listing and certificate of conformance for each lot of JANTXV1N4618D-1.
What is the maximum reverse leakage current for JANTXV1N4618D-1?
JANTXV1N4618D-1 specifies a maximum reverse leakage current (IR) of 0.5 µA at VR = 2.0 V and 25 °C, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision reference applications where load currents are sub-microampere.
Can JANTXV1N4618D-1 be used in surface-mount designs?
No - JANTXV1N4618D-1 uses the axial-leaded DO-35 (DO-204AH) glass package and is not compatible with SMT reflow or pick-and-place processes. For surface-mount equivalents, consider JANTXV1N4618US-1 (DO-213AA) or 1N4618UR-1 (DO-213AA, commercial grade), both sharing identical Zener characteristics but differing in qualification level and packaging.
What is the noise performance of JANTXV1N4618D-1?
JANTXV1N4618D-1 exhibits a maximum noise density of 1 µV/√Hz at 250 mA Zener test current, as specified in the Electrical Characteristics table. This ultra-low noise is achieved due to its metallurgically bonded junction and is measured in the 1 kHz–3 kHz band per Figure 1. This makes JANTXV1N4618D-1 especially valuable in high-fidelity analog signal chains, such as precision ADC references and low-distortion sensor interfaces.
