JANTX1N4462/TR

Single Zener Diodes Overview

The JANTX1N4462/TR is a Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 7.5V with a tolerance of 2%. The device is rated for a power dissipation of 1.5W and utilizes silicon as the semiconductor material. It is housed in a hermetically sealed glass package, specifically the O-LELF-R2 form factor, which contains two terminals. This component is designed for unidirectional operation and includes metallurgically bonded internal structures.

Single Zener Diodes Feature Summary

• Hermetically sealed construction using a voidless-glass encapsulation method to ensure environmental stability.
• Military qualification compliant with MIL-PRF-19500/406 standards for high-reliability applications.
• Metallurgical bonding technology employed within the device structure for enhanced mechanical integrity.

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic systems
• Overvoltage protection circuits requiring hermetic sealing
• High-reliability aerospace instrumentation

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging if reel handling is required for assembly. Confirm the exact Zener voltage tolerance and power rating against the current official datasheet, as variations may exist between standard and lot charge versions. Ensure the procurement specification explicitly requires the JANTX grade to meet the necessary military qualification standards.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed Zener diode with a 7.5V reference is required for harsh environments. The JANTX designation ensures compliance with specific military reliability standards. Consider the 1.5W power dissipation capability and the through-hole glass package constraints during PCB layout and thermal management planning.

Single Zener Diodes Part Context

This part belongs to the 1N4460 series of Zener voltage regulators produced by Microsemi (now Microchip). These devices are characterized by their robust glass passivation and hermetic sealing, distinguishing them from standard commercial equivalents. The series covers a range of voltage values, with the 1N4462 providing a specific 7.5V regulation point.

Single Zener Diodes Replacement Considerations

Consult official substitution lists for equivalent JANTX or JAN grade parts within the same voltage class. Verify pinout compatibility and hermetic seal requirements before replacing with non-military qualified alternatives.
