Product details
Overview
JANTXV1N4114C-1 from Microsemi is a 500 mW, 20 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JANTXV1N4114C-1 datasheet, JANTXV1N4114C-1 pinout, JANTXV1N4114C-1 application, or JANTXV1N4114C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), low noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and military-grade reliability qualification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 20.0 V at 250 mA test current, exhibiting dynamic impedance of 150 Ω at IZT and reverse leakage current ≤0.01 µA at VR = 15.2 V. Its metallurgical bond construction ensures stable long-term voltage regulation under thermal cycling.
Designed for operation across -65 °C to +175 °C junction temperature range, it delivers stable regulation with linear power derating from 500 mW at 25 °C to zero at 175 °C, and features minimal capacitance (~21 pF) and inherent radiation hardness per Microsemi MicroNote 050.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4114US-1 | Same 20 V ±2% Zener voltage, but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated SMT production and board space constraints outweigh manual assembly needs |
| JANS1N4114C-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500 reliability level) | Required for spaceflight and nuclear-hardened systems where JANTXV is insufficient | Select only when mission-critical radiation tolerance and extended screening per MIL-STD-883 are mandated |
Compared with JANTXV1N4114C-1, the 1N4114US-1 offers identical regulation performance in a space-saving SMT form factor, while JANS1N4114C-1 provides enhanced screening and radiation assurance-neither is pin-compatible due to differing packages or qualification scope, making them application-specific alternatives rather than drop-in replacements.

FAQ
What is the Zener voltage tolerance of JANTXV1N4114C-1?
JANTXV1N4114C-1 has a nominal Zener voltage of 20.0 V with a tolerance of ±2%, denoted by the "C" suffix in its part number per MIL-PRF-19500/435 nomenclature. This tight tolerance ensures predictable regulation in precision analog circuits and meets stringent requirements for aerospace and defense applications where reference accuracy is critical. The JANTXV1N4114C-1 maintains this specification across its full rated temperature range.
Is JANTXV1N4114C-1 RoHS compliant?
No, JANTXV1N4114C-1 is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTXV1N4114C-1 uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements and ensure long-term reliability under thermal cycling and harsh environmental conditions.
What is the maximum Zener test current for JANTXV1N4114C-1?
The maximum Zener test current (IZT) for JANTXV1N4114C-1 is 250 mA, as specified in the Electrical Characteristics table. This current defines the operating point at which the 20.0 V Zener voltage and 150 Ω dynamic impedance are measured. Operation at IZT ensures optimal regulation stability and low noise performance, and the JANTXV1N4114C-1 is rated for continuous dissipation up to 500 mW at 25 °C ambient with appropriate thermal derating.
Does JANTXV1N4114C-1 have radiation hardness certification?
Yes, JANTXV1N4114C-1 exhibits inherent radiation hardness validated per Microsemi MicroNote 050. While not individually tested to specific TID levels in standard qualification, its metallurgically bonded glass construction and process design provide proven resilience in total ionizing dose environments typical of avionics and space applications. This characteristic is intrinsic to the JANTXV1N4114C-1 family and forms part of its suitability for high-reliability deployment without additional hardening.
What is the thermal resistance junction-to-lead for JANTXV1N4114C-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4114C-1 is 250 °C/W when measured with 3/8 inch (10 mm) lead length from the body, per MIL-PRF-19500/435 test conditions. This value enables accurate thermal modeling for lead-mounted heatsinking and confirms the JANTXV1N4114C-1's ability to sustain 500 mW dissipation with controlled junction temperature rise under proper mechanical mounting.
