Overview
The 2N2324A is a silicon controlled rectifier (SCR) manufactured by Microchip Technology. It is housed in a TO-5 metal can package designed for through-hole mounting. The component operates within a temperature range of -65°C to 125°C. Key electrical specifications include a maximum repetitive peak off-state voltage and a maximum peak gate power rating of 0.1 W. This device functions as a unidirectional semiconductor switch suitable for high-voltage control applications.
Feature Summary
- Utilizes a robust TO-5 metal can package for reliable through-hole integration
- Engineered for high-temperature operation up to 125°C
- Features a low maximum peak gate power requirement of 0.1 W
Applications
- High-voltage switching circuits
- Industrial control systems requiring thermal stability
- Power electronics protection mechanisms
Procurement Notes
Verify the specific manufacturer source, as the 2N2324A designation appears across multiple vendors including Microsemi and Digitron. Confirm that the received component matches the required TO-5 package and electrical ratings. Check lifecycle status carefully, as some sources indicate obsolete status for certain manufacturers. Ensure compatibility with existing board layouts before procurement.
Selection Notes
Select this component when a hermetically sealed SCR is required for harsh environments. The TO-5 package offers superior thermal dissipation compared to plastic packages. Consider the 0.1 W gate power limit when designing trigger circuits. Verify voltage ratings against peak line conditions to ensure adequate safety margins for the specific application requirements.
Part Context
This part belongs to the family of silicon controlled rectifiers used for power switching. It shares functional similarities with other TO-5 packaged SCRs but is distinct due to its specific voltage and gate power characteristics. The component serves as a foundational element in analog and digital power control designs where reliability is paramount.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching TO-5 package dimensions, voltage ratings, and gate power limits. Consult official manufacturer substitution guides for verified alternatives.
