1N4460CUS

Single Zener Diodes Overview

The Microchip Technology 1N4460CUS is a surface mount Zener voltage regulator diode with a nominal breakdown voltage of 6.2 V and a 2% tolerance, indicated by the 'C' suffix. It features a voidless hermetically sealed glass package designed for high-reliability applications. The device is qualified to MIL-PRF-19500/406 standards and supports steady-state power dissipation up to 1.5 W at 25°C ambient temperature.

Single Zener Diodes Feature Summary

• Voidless hermetically sealed glass construction with internal metallurgical bonds
• Military qualification per MIL-PRF-19500/406 for JAN, JANTX, JANTXV, and JANS levels
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation in high-reliability systems
• Applications where failure cannot be tolerated
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level and tolerance. Confirm RoHS compliance status as it varies by grade. Ensure the procurement documentation references the correct military specification qualification. Check for lead-based terminal availability if required by the application environment.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference with tight 2% tolerance is required in a surface mount form factor. Consider the 1.5 W power rating and thermal resistance characteristics for heat dissipation planning. Verify that the operating temperature range aligns with the -65°C to +175°C junction limits specified for the series.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5 Watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts. The 'CUS' designation specifically denotes the JANS reliability level, 2% tolerance, and MELF surface mount package configuration.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 6.2 V nominal voltage, 2% tolerance, and 1.5 W power rating. Equivalent parts should offer similar hermetic sealing and MIL-PRF-19500/406 qualification. Verify pinout compatibility and thermal performance characteristics before substitution.
