Product details
Overview
JANTXV1N4114C-1/TR from Microsemi is a 20 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTXV1N4114C-1/TR datasheet, JANTXV1N4114C-1/TR pinout, JANTXV1N4114C-1/TR application, or JANTXV1N4114C-1/TR 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 radiation-hardened qualification.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 20.0 V at 250 mA test current, exhibiting low dynamic impedance (150 Ω) and minimal capacitance (typical 4 pF). Its metallurgical bond construction ensures stable breakdown characteristics across temperature extremes.
Qualified to JANTXV per MIL-PRF-19500/435, it supports operation from –65 °C to +175 °C junction temperature, with thermal resistance junction-to-lead of 250 °C/W and linear power derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications

| Power Dissipation | 500 mW @ 25 °C - supports stable operation in compact, convection-cooled designs |
| Dynamic Impedance ZZT | 150 Ω @ 250 mA - low AC impedance ensures tight regulation under varying load conditions |
| Noise Density | 1 µV/√Hz @ 250 mA - ultra-low noise critical for precision analog references and sensor excitation |
| Temp. Coefficient αVZ | +0.090 %/°C - predictable positive drift enables accurate thermal compensation in wide-temp systems |
| Reverse Leakage IR | 0.01 µA @ 15.2 V - negligible leakage preserves accuracy in high-impedance bias networks |
| Junction Temp. Range | –65 °C to +175 °C - enables deployment in military avionics, downhole tools, and space-qualified electronics |

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/TR | Same 20 V ±2% Zener, but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or high-vibration leaded mounting | Select when automated SMT production, board space constraints, or vibration resistance outweigh axial-lead serviceability needs. |
| JANTXV1N4114-1/TR | Identical 20 V nominal Zener but with ±5% tolerance (no C suffix); otherwise identical qualification and construction | Acceptable where system-level calibration compensates for wider initial tolerance; lower cost where precision not required | Select when absolute voltage accuracy is secondary to cost and qualification level remains critical. |
Compared with JANTXV1N4114C-1/TR, the JANTXV1N4114-1/TR offers reduced initial accuracy but same reliability grade, while the 1N4114US-1/TR delivers identical electrical performance in a surface-mount form factor-neither is pin-compatible due to differing packages and mounting methods.

FAQ
What is the Zener voltage tolerance of JANTXV1N4114C-1/TR?
JANTXV1N4114C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This is tighter than the standard ±5% tolerance of non-suffixed variants like JANTXV1N4114-1/TR, enabling higher initial accuracy in uncalibrated systems without trimming.
Is JANTXV1N4114C-1/TR suitable for high-temperature operation?
Yes, JANTXV1N4114C-1/TR is rated for junction temperatures from –65 °C to +175 °C and qualified to MIL-PRF-19500/435 JANTXV level. Its metallurgical bond construction and hermetic DO-35 package ensure stable regulation and parameter integrity across this full military temperature range.
What does the "TR" suffix mean in JANTXV1N4114C-1/TR?
The "TR" suffix in JANTXV1N4114C-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated SMT placement equipment. It does not affect electrical specifications or qualification level-only the delivery format differs from bulk or ammo-pack options.
How does the noise performance of JANTXV1N4114C-1/TR compare to standard Zeners?
JANTXV1N4114C-1/TR delivers 1 µV/√Hz noise density at 250 mA, significantly lower than typical commercial Zeners (often >10 µV/√Hz). This ultra-low noise stems from its metallurgical bond structure and is confirmed in Microsemi's T4-LDS-0245-2 datasheet, making it suitable for precision analog references.
Can JANTXV1N4114C-1/TR replace JANTXV1N4114-1/TR in existing designs?
JANTXV1N4114C-1/TR can directly replace JANTXV1N4114-1/TR electrically and mechanically, as both share identical DO-35 package, JANTXV qualification, and 20 V nominal Zener voltage-the only difference is the tighter ±2% tolerance of the "C" variant, which improves initial accuracy without layout changes.
