JANTX1N4487C

Single Zener Diodes Overview

The JANTX1N4487C is a hermetically sealed Zener diode manufactured by Microsemi. It features a glass axial leaded package designed for through-hole mounting. The device provides a nominal Zener voltage of 82 V with a dynamic impedance of 160 Ohms. It operates within an extended temperature range from -65°C to +175°C and is classified under the JAN, JANTX, JANTXV, and JANS series per MIL-PRF-19500/406.

Single Zener Diodes Feature Summary

• Hermetically sealed construction in a glass axial leaded package
• Extended operating temperature range suitable for harsh environments
• Compliance with military reliability standards

Single Zener Diodes Applications

• Voltage regulation in aerospace systems
• Overvoltage protection circuits
• Reference voltage generation in high-reliability electronics

Single Zener Diodes Procurement Notes

Verify that the specific order includes the 'C' suffix, as this indicates a tighter tolerance variant compared to the standard JANTX1N4487. Confirm RoHS status, as military-grade components often fall outside standard compliance directives. Ensure the supplier provides traceability documentation required for defense or space applications.

Single Zener Diodes Selection Notes

Select this component when a stable 82 V reference is required in extreme thermal conditions. The JANTX1N4487C offers higher precision than the base model. Consider the physical dimensions of the DO-35 style package during PCB layout. Evaluate power dissipation requirements against the device's thermal limits.

Single Zener Diodes Part Context

This part belongs to the 1N4460 through 1N4496 series of high-power Zener diodes. These devices are metallurgically bonded silicon junctions designed for rugged performance. The series is widely used in critical electronic systems where failure is not an option.

Single Zener Diodes Replacement Considerations

JANTX1N4487 serves as the standard tolerance equivalent. JANTXV1N4487 provides even tighter voltage tolerance specifications.
