For engineers reviewing the JANTXV1N4118D-1 datasheet, JANTXV1N4118D-1 pinout, JANTXV1N4118D-1 application, or JANTXV1N4118D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), temperature coefficient (+0.090 %/°C), noise density (1 µV/√Hz), maximum Zener current (20.5 mA), and hermetic DO-35 packaging for radiation-hardened environments.
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, exhibiting low dynamic impedance (150 Ω) and minimal capacitance (<1 pF typical). Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
The JANTXV1N4118D-1 delivers 1% initial voltage tolerance and a positive temperature coefficient of +0.090 %/°C, enabling predictable drift behavior in temperature-varying circuits. It meets MIL-STD-750 method 1020 for ESD insensitivity and supports stable operation under reverse-biased conditions up to rated power dissipation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4118D-1 | Same electrical specs; qualified to JANS (highest military reliability level) with full radiation testing | Required for Class S spaceflight hardware where total ionizing dose >100 krad(Si) is expected | Select JANS1N4118D-1 only when JANS-level screening and radiation data are mandated |
| 1N4118UR-1 | Same VZ, tolerance, and power rating; DO-213AA surface-mount package instead of DO-35 | Used in automated SMT assembly lines where axial-leaded components are incompatible with pick-and-place | Choose 1N4118UR-1 when board space constraints or manufacturing process require SMT mounting |
Compared with JANTXV1N4118D-1, JANS1N4118D-1 adds full radiation characterization and extended screening but increases cost and lead time; 1N4118UR-1 retains identical regulation performance while enabling PCB miniaturization and automated assembly-neither is pin-compatible due to differing packages.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4118D-1?
JANTXV1N4118D-1 has a nominal Zener voltage of 27.0 V with a tight ±1% tolerance at 250 mA test current. This specification is guaranteed per MIL-PRF-19500/435 JANTXV screening and applies across the full -65 °C to +175 °C junction temperature range. The 1% tolerance eliminates need for external calibration in high-accuracy reference designs.
Is JANTXV1N4118D-1 suitable for high-temperature environments?
Yes, JANTXV1N4118D-1 is rated for junction temperatures from -65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgically bonded glass construction and hermetic DO-35 package ensure parametric stability under sustained thermal stress, making it appropriate for engine-mounted avionics and downhole oilfield electronics.
Does JANTXV1N4118D-1 meet radiation hardness requirements?
JANTXV1N4118D-1 is inherently radiation-hardened per Microsemi MicroNote 050, with demonstrated tolerance to total ionizing dose (TID) levels sufficient for low-earth orbit missions. While not fully characterized to JANS-level radiation standards, its construction provides reliable operation in moderate-radiation environments such as UAV flight controllers and tactical communications equipment.
What is the noise performance of JANTXV1N4118D-1?
JANTXV1N4118D-1 exhibits a maximum noise density of 1 µV/√Hz at 27.0 V and 250 mA, measured in the 1 kHz–3 kHz band. This ultra-low noise characteristic results from optimized metallurgical bonding and low-capacitance structure, making JANTXV1N4118D-1 ideal for precision analog references where noise-induced errors must remain below 10 µV RMS.
How is polarity marked on JANTXV1N4118D-1?
JANTXV1N4118D-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be connected to the higher-potential node during Zener regulation. This marking complies with JEDEC standard DO-35 orientation and is verified per MIL-STD-750 method 2026 for solderability and visual inspection in high-reliability assembly processes.
