Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4119US-1 | Same 28.0 V, ±2%, DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mounting | Select when board space is constrained and automated placement is required |

FAQ
What is the Zener voltage tolerance of JANTXV1N4119C-1/TR?
JANTXV1N4119C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its measured VZ at 250 mA test current falls within 27.44 V to 28.56 V at 25 °C, enabling tighter regulation than standard ±5% variants without requiring external calibration.
Is JANTXV1N4119C-1/TR RoHS compliant?
No, JANTXV1N4119C-1/TR is not RoHS compliant. Per the nomenclature guide, RoHS compliance (e3 suffix) is available only on commercial-grade versions. JANTXV-level parts retain tin-lead plating to meet MIL-STD-750 solderability requirements and avoid lead-free reliability concerns in high-reliability applications.
What is the maximum junction temperature rating for JANTXV1N4119C-1/TR?
JANTXV1N4119C-1/TR is rated for junction and storage temperatures from -65 °C to +175 °C. This wide range supports operation in spacecraft thermal vacuum environments and engine-mounted avionics where ambient extremes exceed commercial limits.
How does the metallurgical bond improve reliability of JANTXV1N4119C-1/TR?
The internal metallurgical bond in JANTXV1N4119C-1/TR eliminates organic adhesives or solder interfaces that degrade under thermal cycling. This construction prevents delamination-induced parameter shift and maintains stable Zener voltage over 10,000+ thermal cycles - a key requirement for MIL-PRF-19500/435 JANTXV qualification.
Can JANTXV1N4119C-1/TR be used in surface-mount designs?
JANTXV1N4119C-1/TR uses a DO-35 axial package and is not designed for surface-mount assembly. For SMT compatibility, Microsemi offers the functionally equivalent 1N4119US-1 in DO-213AA package - same 28.0 V ±2% spec but with gull-wing leads and tape-and-reel packaging.
