1N4465CUS

Single Zener Diodes Overview

The Microchip Technology 1N4465CUS is a surface mount Zener voltage regulator with a nominal breakdown voltage of 10.0 V and a 2% tolerance, indicated by the 'C' suffix. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5 W at 25°C ambient. The device features a hermetically sealed voidless glass MELF package (D-5A) with internal metallurgical bonds. Electrical characteristics include a maximum dynamic impedance of 5 Ohms at a test current of 25 mA and a maximum reverse leakage current of 0.3 µA.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction with tungsten slugs for robustness
• Military qualification per MIL-PRF-19500/406 standards
• Internal Category III metallurgical bonding for enhanced reliability
• Triple-layer passivation providing inherent radiation hardness

Single Zener Diodes Applications

• High-reliability aerospace systems requiring failure-intolerant components
• Voltage regulation across broad operating current and temperature ranges
• Radiation-hardened electronic circuits in space environments
• Surface mount equivalents for JEDEC registered axial-lead series

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'C' confirms the specific 2% voltage tolerance required for the design. Confirm the package type matches the D-5A MELF footprint on the PCB layout. Ensure the procurement specification aligns with the military qualification level if the application demands compliance with MIL-PRF-19500/406 standards.

Single Zener Diodes Selection Notes

Select this component when a surface mount solution is needed to replace traditional axial-lead diodes without compromising reliability. The 10.0 V rating suits applications requiring precise regulation near this threshold. Consider the 1.5 W power dissipation capability and thermal resistance values when designing heat management strategies for the enclosure.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5 Watt Glass Zener Diodes. These devices are designed as surface mount equivalents to popular JEDEC registered series, offering industry-recognized performance in a compact form factor suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts from the 1N4460US–1N4496US series or commercial versions like the 1N4465. Verify that substitute components match the D-5A MELF package dimensions and maintain equivalent hermetic sealing and radiation hardness specifications.
