Overview
The CD486B is a general-purpose silicon signal diode manufactured by Microchip Technology. It features a single junction configuration with a peak inverse voltage of 250 V and a maximum forward current of 200 mA. The device is designed for robust operation within an extended temperature range from -65°C to +175°C. Electrical characteristics are verified at 25°C, ensuring reliable performance in demanding environments.
Feature Summary
- Constructed from silicon material with complete junction protection via silicon dioxide.
- Compatible with standard wire bonding and die attach techniques for integrated circuit assembly.
Applications
- General purpose rectification in electronic circuits
- Signal processing applications requiring high voltage isolation
- Integration into semiconductor devices using wire bonding
Procurement Notes
Verify the specific manufacturer designation, as historical data links this part number to Microsemi, now part of Microchip Technology. Confirm the package type corresponds to an uncased chip or die format rather than a standard discrete component housing. Ensure compliance requirements align with the lead-free status indicated in legacy specifications.
Selection Notes
Select this component when a high-voltage silicon diode with a 250 V rating is required for signal or power rectification. The wide operating temperature range supports harsh environment applications. Consider the uncased chip form factor if integrating directly into custom substrates or hybrid circuits.
Part Context
The CD486B belongs to a family of general-purpose silicon diodes that includes variants such as CD483B, CD485B, and CD645. These components share similar protective structures and bonding compatibility but differ in voltage and current ratings. This series is designed for reliability in industrial and military-grade semiconductor assemblies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical equivalence with other members of the CD48x series, such as CD485B or CD483B, based on specific voltage and current requirements.
