Triacs Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to ensure accuracy. Confirm that the suffix indicates the correct packaging and variant specifications. Cross-reference the datasheet for any recent updates regarding pinout configurations or absolute maximum ratings before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 35 A RMS current rating and 800 V blocking voltage are required in a TO-220AB-3 package. Ensure the application environment stays within the specified -40 C to +150 C operating temperature range. Verify that the gate trigger requirements align with the 1.3 V and 50 mA specifications provided in the official datasheet.

Triacs Part Context

This component belongs to the Qxx35xH series from Littelfuse, which specializes in high-temperature thyristor solutions. The series is engineered for reliability in industrial power electronics where standard components may fail due to thermal stress. It serves as a specialized alternative for general-purpose triacs in high-demand scenarios.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Do not assume compatibility with other 35 A triacs without verifying voltage ratings, package dimensions, and thermal characteristics against the original datasheet.
