Product details
Overview
JANTXV1N4119D-1 from Microsemi is a 500 mW, 28.0 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability applications including voltage regulation in military power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4119D-1 datasheet, JANTXV1N4119D-1 pinout, JANTXV1N4119D-1 application, or JANTXV1N4119D-1 equivalent, key selection criteria include its 28.0 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 21.3 V, +0.095 %/°C temperature coefficient, and hermetically sealed DO-35 package rated for -65 °C to +175 °C operation.
Technical Context
This device operates as a two-terminal voltage reference in reverse-bias breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable Zener characteristics under thermal cycling and radiation exposure, supporting compliance with MIL-STD-750 method 1020 for ESD insensitivity.
The JANTXV1N4119D-1 exhibits low noise density (1 µV/√Hz typical at lower voltages), minimal capacitance (≈3 pF per Figure 3), and linear power derating from 500 mW at 25 °C to zero at 175 °C - enabling use in precision analog circuits where voltage stability across temperature and current variation is critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4119US-1 | Same electrical specs but in DO-213AA surface-mount package | Requires SMT assembly; no axial through-hole mounting | Select for space-constrained PCBs where automated placement is preferred |
| 1N4119UR-1 | Commercial-grade (non-mil-qualified), same DO-35 package and 28 V/±1% specs | Lacks MIL-PRF-19500 screening; not suitable for defense/aerospace deployment | Select for cost-sensitive industrial prototypes where mil-spec is not mandated |
Compared with JANTXV1N4119D-1, the JANTXV1N4119US-1 offers identical regulation performance in a smaller footprint but requires rework of board layout and assembly process, while the 1N4119UR-1 provides functional equivalence at lower cost but without radiation hardness or extended temperature validation.

FAQ
What is the Zener voltage tolerance of JANTXV1N4119D-1?
JANTXV1N4119D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 28.0 V Zener voltage is guaranteed to fall between 27.72 V and 28.28 V when measured at 250 mA test current and 25 °C ambient temperature, supporting high-accuracy reference designs without trimming.
Is JANTXV1N4119D-1 suitable for high-temperature operation?
Yes, JANTXV1N4119D-1 is rated for junction temperatures from -65 °C to +175 °C and features hermetic DO-35 packaging. Its metallurgical bond construction and MIL-PRF-19500/435 JANTXV qualification ensure stable Zener voltage and low leakage even after prolonged exposure to 175 °C ambient, making it appropriate for downhole, avionics, and engine-control applications.
What does the "JANTXV" prefix indicate for JANTXV1N4119D-1?
The "JANTXV" prefix on JANTXV1N4119D-1 signifies compliance with the highest commercial/military hybrid qualification level under MIL-PRF-19500/435 - including rigorous screening for burn-in, temperature cycling, and parameter verification. It guarantees traceability, lot control, and extended reliability beyond standard JAN or JANTX levels.
How is polarity marked on JANTXV1N4119D-1?
JANTXV1N4119D-1 uses a single black band on the glass body to mark the cathode terminal. The diode must be operated with the banded end connected to the higher-potential node (e.g., unregulated input rail) and the unbanded end (anode) tied to ground or lower potential to achieve Zener regulation behavior.
Does JANTXV1N4119D-1 meet RoHS requirements?
No, JANTXV1N4119D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants like 1N4119-1e3. The JANTXV1N4119D-1 retains traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
