JANS1N4460US

Single Zener Diodes Overview

The JANS1N4460US is a surface-mount Zener voltage regulator diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.2 V with a maximum power dissipation of 1.5 W at 25°C ambient temperature. The device utilizes silicon as the semiconductor material and operates within a junction temperature range of -65°C to +175°C. It is housed in a D-5A glass package, which corresponds to the SQ-MELF form factor, providing a hermetically sealed environment. This component is qualified under MIL-PRF-19500/406 for high-reliability applications.

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required military qualification level. Confirm package orientation and pinout compatibility with the target PCB footprint. Ensure storage conditions adhere to moisture sensitivity levels if applicable. Validate that the supplier provides traceability documentation consistent with defense procurement requirements.

Single Zener Diodes Selection Notes

Select this component when a robust, hermetically sealed Zener diode is required for extreme environmental conditions. The 1.5 W power rating supports moderate current handling in compact surface-mount layouts. Consider the D-5A package dimensions against available board space. Verify thermal derating requirements for operation above 25°C ambient temperatures.

Single Zener Diodes Part Context

This device belongs to the 1N4460 series of Zener diodes, which are industry-standard voltage regulators. The JANS prefix indicates the highest reliability grade within the military qualification spectrum. Similar parts in the series offer varying Zener voltages while maintaining identical power and package characteristics.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANS-qualified versions from the same series, such as JANS1N4461US. Cross-brand replacements must match the 6.2 V Zener voltage, 1.5 W power rating, and D-5A MELF package geometry. Verify that alternative sources maintain equivalent MIL-PRF-19500/406 certification.
