Procurement Notes
Verify the specific suffix 'G' against the manufacturer's datasheet to confirm RoHS compliance status. Ensure the ordering documentation explicitly references Littelfuse as the source, as distributor listings may vary in accuracy regarding environmental certifications and exact package style specifications.
Selection Notes
Select this component when a 600 V blocking capability is required alongside a 4 A RMS current rating. The sensitive gate characteristic makes it suitable for logic-level triggering applications. Verify that the TO-225AA package dimensions align with the available chassis or wire-mount space in the target assembly.
Part Context
This part belongs to the Littelfuse C106 series of silicon-controlled rectifiers. These devices are engineered for high-volume consumer applications where operational reliability is critical.
