Triacs Procurement Notes
Verify the specific suffix designation against official Littelfuse documentation to confirm pinout and isolation characteristics. Confirm RoHS compliance status directly from the manufacturer datasheet prior to integration. Ensure the procurement channel provides valid traceability records for quality assurance purposes.
Triacs Selection Notes
Select this component when a 400 V blocking voltage and 25 A continuous current capacity are required. Verify that the driving circuit can supply the necessary 80 mA gate trigger current. Consider the TO-220 package dimensions for adequate heat sinking requirements during operation.
Triacs Part Context
This part belongs to the Qxx25xx series of triacs manufactured by Littelfuse. The series is engineered for general-purpose AC power switching. The Q4025R6TP variant specifically denotes the 400 V rating and standard gate sensitivity configuration within this product family.
Triacs Replacement Considerations
Cross-reference with Q4025R5 or Q4025J6TP only if gate trigger current specifications align with the existing design constraints. Verify package compatibility and thermal resistance values before substituting.
