Product details
Overview
JANTXV1N4118C-1 from Microsemi is a 500 mW, 27.0 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4118C-1 datasheet, JANTXV1N4118C-1 pinout, JANTXV1N4118C-1 application, or JANTXV1N4118C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and JANTXV-level qualification for extended temperature operation (-65 °C to +175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 27.0 V at 250 mA test current (IZT), exhibiting low dynamic impedance (150 Ω) and minimal noise density (1 µV/√Hz) - critical for stable reference generation in analog signal chains and power supply feedback loops.
Its metallurgical bond construction ensures robust thermal performance (RθJL = 250 °C/W) and radiation hardness per Microsemi MicroNote 050, supporting operation across -65 °C to +175 °C junction temperature range without derating until lead temperature exceeds 50 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4118US-1 | Same 27.0 V ±2% Zener voltage, but in surface-mount DO-213AA package; RθJA = 400 °C/W vs. 300 °C/W for DO-35. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board upgrades. | Select when automated SMT production and space-constrained layouts outweigh manual assembly flexibility. |
| JAN1N4118C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTXV). | Lacks JANTXV's extended burn-in, thermal shock, and life test requirements - not approved for Class H or Class S programs. | Select only for non-mission-critical commercial-aerospace subsystems where full JANTXV screening is not mandated. |
Compared with JANTXV1N4118C-1, the 1N4118US-1 offers footprint reduction at the cost of thermal performance and assembly compatibility, while JAN1N4118C-1 reduces cost and screening rigor but forfeits JANTXV's qualification for high-integrity systems requiring MIL-PRF-19500/435 Level 3 assurance.

FAQ
What is the Zener voltage tolerance of JANTXV1N4118C-1?
JANTXV1N4118C-1 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a nominal 27.0 V Zener voltage ranging from 26.46 V to 27.54 V at 250 mA test current (IZT) and 25 °C ambient, enabling tighter regulation than standard ±5% variants in precision feedback circuits.
Is JANTXV1N4118C-1 suitable for high-temperature operation?
Yes, JANTXV1N4118C-1 is rated for junction temperatures from -65 °C to +175 °C and is fully characterized across this range. Its power dissipation is linearly derated from 500 mW at 25 °C lead temperature to zero at 175 °C, making it suitable for downhole, engine-mounted, and avionics applications where ambient temperatures exceed 125 °C.
Does JANTXV1N4118C-1 meet MIL-PRF-19500/435 requirements?
Yes, JANTXV1N4118C-1 is qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including extended environmental screening such as thermal shock, life testing, and burn-in. This qualification ensures compliance with stringent military and aerospace standards for reliability, traceability, and performance consistency across production lots.
What is the noise performance of JANTXV1N4118C-1?
JANTXV1N4118C-1 exhibits a maximum noise density of 1 µV/√Hz at 250 mA Zener test current, measured in the 1 kHz–3 kHz band. This ultra-low noise characteristic makes JANTXV1N4118C-1 appropriate for use as a voltage reference in high-resolution data acquisition systems and low-noise analog signal conditioning circuits.
How is polarity marked on JANTXV1N4118C-1?
JANTXV1N4118C-1 uses a cathode band marking on the glass DO-35 body to indicate polarity. The banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking complies with JEDEC standards and is visible under standard visual inspection during manual or automated assembly.
