Product details
Overview
JANTXV1N4114D-1 from Microsemi is a 500 mW, 20 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense systems. It delivers 15.2 mA Zener test current at 20 V, exhibits 150 Ω dynamic impedance, and maintains low noise density (1 µV/√Hz) with temperature coefficient of +0.090 %/°C.
For engineers reviewing the JANTXV1N4114D-1 datasheet, JANTXV1N4114D-1 pinout, JANTXV1N4114D-1 application, or JANTXV1N4114D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, JANTXV-level military qualification, DO-35 hermetic glass package, 20 V regulation point, and radiation-hardened construction per MicroNote 050.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band indicating polarity. Its metallurgical bond ensures stable junction characteristics across -65 °C to +175 °C operating range and supports operation under high-reliability environmental stress profiles including thermal cycling and radiation exposure.
The JANTXV1N4114D-1 exhibits 150 Ω dynamic impedance at 250 µA test current, 0.01 µA maximum reverse leakage at 15.2 V, and minimal capacitance (~5 pF typical), enabling stable regulation in low-noise analog references and power supply feedback loops where low parasitic capacitance and predictable impedance are critical.

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 DO-213AA surface-mount package; no JANTXV qualification | Lacks MIL-PRF-19500/435 validation; unsuitable for flight hardware requiring JANTXV traceability | Select only for commercial or industrial PCBs where surface-mount assembly and cost reduction outweigh military qualification needs |
| JANTXV1N4114-1 | Same 20 V nominal rating but ±5% tolerance; identical JANTXV qualification and DO-35 package | Higher voltage uncertainty requires tighter system-level calibration; less suitable for precision references | Choose when budget constraints preclude 1% tolerance but JANTXV reliability and form factor remain mandatory |
Compared with JANTXV1N4114D-1, the JANTXV1N4114-1 offers lower cost and same reliability at ±5% tolerance, while the 1N4114US-1 enables SMT layout but forfeits military qualification-making JANTXV1N4114D-1 the sole choice for 20 V, 1%, JANTXV-compliant through-hole regulation.

FAQ
What is the Zener voltage tolerance of JANTXV1N4114D-1?
JANTXV1N4114D-1 has a Zener voltage tolerance of ±1% at 20.0 V, as indicated by the "D" suffix in its nomenclature per MIL-PRF-19500/435 standards. This tight tolerance is verified during JANTXV-level screening and enables high-accuracy voltage references without post-manufacture trimming. The JANTXV1N4114D-1 achieves this specification at 250 µA test current and 25 °C ambient conditions.
Is JANTXV1N4114D-1 qualified to MIL-PRF-19500/435?
Yes, JANTXV1N4114D-1 is fully qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including rigorous environmental testing, lot traceability, and failure analysis reporting. This qualification covers all parameters in the official Microsemi T4-LDS-0245-2 datasheet and confirms suitability for high-reliability applications such as airborne electronics and spaceflight subsystems.
What package type does JANTXV1N4114D-1 use?
JANTXV1N4114D-1 uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with tin-lead plating, per JEDEC standard dimensions. The cathode is marked by a visible band on the glass body, and the device weighs approximately 0.2 grams. This package supports manual and wave soldering per MIL-STD-750 method 2026.
What is the maximum reverse leakage current for JANTXV1N4114D-1?
The maximum reverse leakage current (IR) for JANTXV1N4114D-1 is 0.01 µA at VR = 15.2 V, as specified in the Electrical Characteristics table of the Microsemi T4-LDS-0245-2 datasheet. This ultra-low leakage supports energy-efficient operation in battery-powered or low-quiescent-current reference designs where standby current must be minimized.
Does JANTXV1N4114D-1 have radiation-hardened characteristics?
Yes, JANTXV1N4114D-1 is inherently radiation hard as documented in Microsemi MicroNote 050, due to its metallurgically bonded construction and glass hermetic sealing. It exhibits no parametric shift or functional failure under total ionizing dose (TID) levels typical of low-earth orbit missions, making it suitable for satellite power and instrumentation without additional shielding.
