Product details
Overview
JANTX1N4114C-1/TR from Microsemi is a 20 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4114C-1/TR datasheet, JANTX1N4114C-1/TR pinout, JANTX1N4114C-1/TR application, or JANTX1N4114C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), dynamic impedance (150 Ω), temperature coefficient (+0.090 %/°C), 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 20.0 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across –65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The JANTX1N4114C-1/TR features a cathode band marking, requires reverse-bias operation (banded end positive), and delivers 150 Ω dynamic impedance at IZT = 250 mA - critical for maintaining regulation accuracy under varying load currents in analog reference and feedback circuits.

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 surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and reflow assembly is required; lacks axial mounting flexibility. | Select when automated SMT placement is mandatory and thermal mass constraints allow lower power derating. |
| JANTXV1N4114C-1 | Identical electrical specs, but qualified to higher JANTXV reliability level with additional burn-in and lot acceptance testing. | Required for mission-critical flight hardware where failure rate must meet <100 FIT per MIL-HDBK-217F. | Choose for launch vehicle avionics or manned spacecraft systems demanding enhanced screening and traceability. |
Compared with JANTX1N4114C-1/TR, the 1N4114US-1 offers SMT compatibility at the cost of reduced thermal dissipation margin, while JANTXV1N4114C-1 adds rigorous screening for ultra-high-reliability programs - neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JANTX1N4114C-1/TR?
JANTX1N4114C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its nominal 20.0 V Zener voltage is guaranteed between 19.6 V and 20.4 V at 250 mA test current and 25 °C ambient, supporting tighter regulation than standard ±5% variants.
Is JANTX1N4114C-1/TR RoHS compliant?
No, JANTX1N4114C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4114C-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements to maintain solderability and reliability in high-reliability applications.
What is the maximum Zener current IZM for JANTX1N4114C-1/TR?
The maximum Zener current IZM for JANTX1N4114C-1/TR is 40 mA, derived from its 500 mW power rating and 20 V nominal Zener voltage (P = V × I → I = 0.5 W / 20 V = 25 mA), with margin added per Microsemi's published IZM value of 40 mA in the Electrical Characteristics table on page 3 of T4-LDS-0245-2.
How does the temperature coefficient affect JANTX1N4114C-1/TR performance?
JANTX1N4114C-1/TR has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 18 mV per 10 °C rise above 25 °C. This predictable positive drift allows designers to compensate reference circuits in wide-temperature-range applications such as airborne radar power supplies.
Can JANTX1N4114C-1/TR be used in surface-mount designs?
No, JANTX1N4114C-1/TR uses an axial-leaded DO-35 package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4114US-1 in DO-213AA package - it shares identical electrical specs but requires reflow soldering and has different thermal derating behavior.
