Procurement Notes
Verify the specific ordering suffix against official Littelfuse documentation to confirm exact electrical characteristics and packaging options. Ensure the selected variant matches the required voltage and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and compliance with relevant regulatory standards such as RoHS.
Selection Notes
Select this SCR based on the 400V blocking voltage and 8A current requirements. Consider the TO-220-2 package for appropriate heat dissipation needs. Verify that the sensing gate sensitivity aligns with the driving circuit's output capability. Ensure the operating temperature range meets the environmental constraints of the final assembly.
Part Context
