- High voltage blocking capability up to 400V
- Robust thermal performance with extended junction temperature range
- Through-hole mounting for secure mechanical attachment
Applications
- Industrial power supply circuits
- Overvoltage protection systems
- General purpose rectification applications
Procurement Notes
Verify the specific datasheet revision and electrical characteristics against the latest official onsemi documentation before integration. Confirm that the TO-220AB package dimensions match the target PCB footprint and thermal management requirements. Ensure the 400V rating aligns with the system's peak voltage stresses. Check for any specific handling instructions related to thyristor sensitivity during assembly processes.
Selection Notes
Select this component when a 400V rated silicon controlled rectifier is required in a TO-220AB package. Consider its suitability for applications needing reliable turn-on characteristics and high surge current handling. Evaluate the thermal resistance and heat sinking needs given the 150°C maximum junction temperature limit. Compare against alternative thyristors if higher voltage ratings or different package styles are necessary for the specific design constraints.
Part Context
This device belongs to the family of silicon controlled rectifiers (SCRs) produced by onsemi. These components are widely used in power electronics for controlling high power loads. The SCR888LFDZG specifically addresses applications requiring medium voltage isolation and robust switching performance. Its classification as an active part indicates ongoing manufacturing support and standard availability within the semiconductor market.
Replacement Considerations
Consult official cross-reference guides for compatible SCRs with matching 400V ratings and TO-220AB packages. Verify pinout compatibility and thermal characteristics before substituting. Ensure any replacement maintains the same electrical specifications and package dimensions to fit existing board layouts.
