Product details
Overview
JANTXV1N4119C-1 from Microsemi is a 500 mW, 28.0 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability regulation. It delivers 21.3 mA maximum Zener current at 25 °C, exhibits 200 Ω dynamic impedance at 250 mA test current, and maintains low noise density of 1 µV/√Hz.
For engineers reviewing the JANTXV1N4119C-1 datasheet, JANTXV1N4119C-1 pinout, JANTXV1N4119C-1 application, or JANTXV1N4119C-1 equivalent, key selection criteria include its 28.0 V nominal Zener voltage with ±2% tolerance, JANTXV reliability qualification, DO-35 axial-leaded hermetic package, 0.5 W power rating, and temperature coefficient of +0.095 %/°C - critical for precision voltage reference and radiation-hardened analog circuits.
Technical Context
This device operates as a reverse-biased voltage regulator with a sharp breakdown knee at 28.0 V under 250 mA test current. Its metallurgical bond construction ensures stable junction characteristics across -65 °C to +175 °C operating range and inherent radiation hardness per Microsemi MicroNote 050.
It features low capacitance (typical <2 pF at 0 V), minimal ESD sensitivity (MIL-STD-750 method 1020), and thermal resistance of 250 °C/W junction-to-lead (3/8″ lead length), enabling stable regulation in high-temp military and aerospace power supply feedback paths.
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 |
|---|---|---|---|
| 1N4119US-1 | Same 28.0 V ±2% Zener voltage, but in surface-mount DO-213AA package; no axial leads | Requires SMT assembly and board layout change; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when space-constrained PCBs demand surface-mount integration and reflow compatibility is available |
| JANTXV1N4118C-1 | 27.0 V ±2% nominal Zener voltage; otherwise identical qualification, package, and electrical specs | Used where 27 V reference is specified in legacy schematics or system-level voltage margining allows 1 V reduction | Select only if system tolerances accommodate 1 V lower reference; not a drop-in replacement due to voltage mismatch |
Compared with JANTXV1N4119C-1, the 1N4119US-1 offers footprint miniaturization at the cost of mechanical robustness and assembly flexibility, while JANTXV1N4118C-1 provides a near-equivalent voltage option for designs with looser reference tolerance budgets - neither is pin-compatible nor electrically interchangeable without circuit review.

FAQ
What is the Zener voltage tolerance of JANTXV1N4119C-1?
JANTXV1N4119C-1 has a nominal Zener voltage of 28.0 V with a ±2% tolerance, indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range of -65 °C to +175 °C per MIL-PRF-19500/435 requirements.
Is JANTXV1N4119C-1 RoHS compliant?
No, JANTXV1N4119C-1 is not RoHS compliant. The "e3" RoHS designation is only available on commercial-grade versions of this family (e.g., 1N4119C-1e3); JANTXV-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability in high-reliability applications, and do not carry the e3 suffix.
What is the maximum Zener current for JANTXV1N4119C-1 at 25 °C?
The maximum Zener current (IZM) for JANTXV1N4119C-1 is 21.3 mA at 25 °C, calculated from its 500 mW power rating and 28.0 V nominal Zener voltage. This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, and assumes thermal equilibrium conditions with proper lead heat sinking.
Does JANTXV1N4119C-1 have radiation hardness certification?
Yes, JANTXV1N4119C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded construction and DO-35 hermetic package provide proven tolerance to total ionizing dose (TID) and displacement damage, making it suitable for satellite, avionics, and nuclear instrumentation without additional hardening.
What package type does JANTXV1N4119C-1 use?
JANTXV1N4119C-1 uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions are specified on page 5 of T4-LDS-0245-2 Rev. 1, with body diameter 1.42–2.29 mm and overall length 3.56–5.08 mm; cathode polarity is marked by a visible band on the glass envelope.
