It delivers stable reference voltage with 200 Ω dynamic impedance at 250 mA test current, 0.01 µA max reverse leakage at 21.3 V, and +0.095 %/°C temperature coefficient.
For engineers reviewing the JANS1N4119C-1/TR datasheet, JANS1N4119C-1/TR pinout, JANS1N4119C-1/TR application, or JANS1N4119C-1/TR equivalent, key selection criteria include Zener voltage tolerance, radiation hardness, MIL-spec qualification level, thermal resistance (250 °C/W junction-to-lead), and low-noise performance (1 µV/√Hz typical below 6.8 V).
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock, critical for space-grade applications.
The JANS1N4119C-1/TR exhibits a positive temperature coefficient (+0.095 %/°C), enabling predictable drift compensation in regulated power supplies and sensor biasing circuits across -65 °C to +175 °C operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4119C-1 | Same electrical specs; qualified to JANTXV level (lower screening rigor than JANS) | Limited to non-spaceflight defense programs requiring high reliability but not full JANS radiation assurance | Select when cost and lead time constraints outweigh need for full JANS radiation hardness and lot acceptance testing |
| 1N4119C-1/TR | Commercial-grade version; RoHS-compliant plating; no MIL-qualification | Suitable only for benign industrial or commercial environments with no radiation or extreme thermal demands | Choose for prototyping or non-critical systems where MIL-spec documentation and traceability are unnecessary |
Compared with JANS1N4119C-1/TR, JANTXV1N4119C-1 offers identical voltage regulation performance with reduced screening depth, while 1N4119C-1/TR eliminates MIL-qualification entirely-making both unsuitable as drop-in replacements where JANS-level radiation hardness or lot traceability is mandated.

FAQ
What is the Zener voltage tolerance of JANS1N4119C-1/TR?
JANS1N4119C-1/TR has a nominal Zener voltage of 28.0 V with ±2% tolerance, as indicated by the "C" suffix in its nomenclature per Microsemi's part numbering convention. This tolerance is guaranteed under standard test conditions (25 °C, 250 mA Zener test current) and applies across the full qualified temperature range when used within derated power limits.
Is JANS1N4119C-1/TR radiation hardened?
Yes, JANS1N4119C-1/TR is inherently radiation hard per Microsemi MicroNote 050 due to its metallurgically bonded construction and hermetic glass package. It is qualified to JANS level per MIL-PRF-19500/435, which includes radiation testing protocols appropriate for spaceflight and nuclear environments.
What does the "TR" suffix mean in JANS1N4119C-1/TR?
The "TR" suffix in JANS1N4119C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated PCB assembly. This packaging option is factory-confirmed and documented in Microsemi's T4-LDS-0245-2 datasheet revision 1, with reel quantities subject to factory consultation.
What is the maximum reverse leakage current for JANS1N4119C-1/TR?
JANS1N4119C-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at 21.3 V (75% of nominal VZ), as specified in the Electrical Characteristics table on page 3 of the official datasheet. This ultra-low leakage supports energy-efficient biasing in battery-powered or low-power systems.
Can JANS1N4119C-1/TR be used in surface-mount designs?
No - JANS1N4119C-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not surface-mount compatible. For SMT equivalents, Microsemi offers the 1N4119UR-1 in DO-213AA and 1PMT4119 in DO-216 packages, but these are commercial-grade and lack JANS qualification.
