Product details
Overview
JANTX1N4114D-1/TR from Microsemi is a 1% tolerance, 20 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JANTX1N4114D-1/TR datasheet, JANTX1N4114D-1/TR pinout, JANTX1N4114D-1/TR application, or JANTX1N4114D-1/TR equivalent, key selection criteria include its 1% Zener voltage tolerance, 150 Ω dynamic impedance at 250 mA, 0.01 µA reverse leakage at 15.2 V, radiation-hardened construction, and hermetically sealed DO-35 package suitable for harsh-environment analog regulation.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded junctions enabling stable breakdown characteristics across -65 °C to +175 °C. Its low noise density (1 µV/√Hz typical at 20 V) and minimal capacitance support high-fidelity analog references and low-jitter timing circuits.
The JANTX qualification confirms compliance with MIL-PRF-19500/435 screening including temperature cycling, hermeticity, and life testing. It exhibits a +0.090 %/°C temperature coefficient and is non-sensitive to ESD per MIL-STD-750 Method 1020.

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 ±1% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair | Select when automated SMT production, space-constrained layouts, or reduced lead inductance are priorities |
| JANTXV1N4114D-1 | Identical electrical specs but qualified to higher JANTXV reliability level with additional screening (e.g., burn-in, lot acceptance tests) | Required for mission-critical flight hardware where failure modes demand stricter process controls and traceability | Select when program requirements mandate JANTXV-level documentation, lot traceability, and extended lifetime testing |
Compared with JANTX1N4114D-1/TR, the 1N4114US-1 offers SMT compatibility at the cost of axial-mount flexibility, while JANTXV1N4114D-1 adds screening rigor for flight-critical systems-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JANTX1N4114D-1/TR?
JANTX1N4114D-1/TR has a nominal Zener voltage of 20.0 V with a guaranteed tolerance of ±1%, as indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified under standard test conditions (25 °C, 250 mA Zener test current) and maintained across its qualified operating temperature range.
Is JANTX1N4114D-1/TR suitable for high-temperature applications?
Yes, JANTX1N4114D-1/TR is rated for junction temperatures from -65 °C to +175 °C and is qualified per MIL-PRF-19500/435 JANTX level, making it suitable for high-temperature applications such as downhole drilling electronics and avionics power systems where sustained operation above 125 °C is required.
What does the "TR" suffix mean in JANTX1N4114D-1/TR?
The "TR" suffix in JANTX1N4114D-1/TR indicates tape-and-reel packaging per EIA-296 standards, enabling automated pick-and-place assembly. This version contains the same electrically and mechanically qualified JANTX-level device as the bulk or ammo-pack versions, with no specification or reliability differences.
How does the noise performance of JANTX1N4114D-1/TR compare to lower-voltage Zeners?
JANTX1N4114D-1/TR exhibits a typical noise density of 1 µV/√Hz at 20 V, consistent with Microsemi's specification that noise falls rapidly below 6.8 V and reaches 1 µV/√Hz at voltages ≥20 V. This makes it among the lowest-noise options in the 1N41xx series for precision analog reference use.
Can JANTX1N4114D-1/TR be used as a replacement for commercial-grade 1N4114 diodes?
JANTX1N4114D-1/TR meets all electrical specifications of commercial 1N4114 devices but adds MIL-PRF-19500/435 JANTX qualification, hermetic sealing, and enhanced screening. It can functionally replace commercial versions in demanding applications, though its higher cost and qualification overhead make it over-specified for benign commercial environments.
