Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4616US-1TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Requires PCB re-layout for SMT assembly; eliminates through-hole mounting | Select when automated assembly and board space reduction are prioritized over legacy through-hole compatibility |
| JAN1N4616D-1/TR | Identical electrical and mechanical specs but qualified only to JAN level (less stringent screening than JANTXV) | Suitable for non-critical subsystems where full JANTXV screening is not mandated | Select when cost sensitivity outweighs requirement for extended burn-in and radiation lot acceptance testing |
Compared with JANTXV1N4616D-1/TR, 1N4616US-1TR offers identical regulation performance in a compact SMT form factor, while JAN1N4616D-1/TR reduces procurement cost by omitting JANTXV-level environmental stress screening-both retain the 2.2 V ±1%, 500 mW, and -0.075 %/°C core specification set.

FAQ
What is the Zener voltage tolerance of JANTXV1N4616D-1/TR?
JANTXV1N4616D-1/TR has a nominal Zener voltage of 2.2 V with ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tight tolerance is achieved through post-process binning and verified during JANTXV-level qualification testing at 25 °C ambient with 250 mA test current.
Is JANTXV1N4616D-1/TR RoHS compliant?
No, JANTXV1N4616D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JANTXV-qualified parts, which retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements.
What is the maximum operating temperature for JANTXV1N4616D-1/TR?
JANTXV1N4616D-1/TR is rated for junction and storage temperatures from -65 °C to +175 °C. Its thermal resistance junction-to-lead is 250 °C/W with 10 mm lead length, enabling reliable operation in high-temperature environments such as downhole tools and avionics enclosures without derating below 500 mW until lead temperature exceeds 50 °C.
How does the temperature coefficient affect JANTXV1N4616D-1/TR performance?
JANTXV1N4616D-1/TR has a temperature coefficient of -0.075 %/°C, meaning its Zener voltage decreases by approximately 1.65 mV per degree Celsius rise. This predictable linear drift allows accurate compensation in precision analog circuits and confirms suitability for applications requiring stable references across wide thermal excursions.
What packaging format does JANTXV1N4616D-1/TR use?
JANTXV1N4616D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package, with cathode identified by a band. The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, supporting automated through-hole insertion while maintaining full JANTXV qualification integrity.
