QJ6008DH3RP

Triacs Overview

The Littelfuse QJ6008DH3RP is an 8 A High Temperature Alternistor Triac solid state switch designed for AC switching and phase control applications. It operates within a voltage range up to 800 V and features a sensitive gate type requiring Quadrant I & IV control, suitable for digital circuitry. The device is housed in a TO-252-3 (D-PAK) surface-mount package with a maximum operating temperature of +150 °C and a minimum of -40 °C. Key electrical parameters include an on-state RMS current of 8 A, an on-state voltage of 1.5 V, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. Leakage current is specified at 10 uA under rated blocking voltage conditions.

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm exact voltage ratings and packaging configurations. Ensure that the ordering information matches the required thermal and electrical specifications for the target application environment before finalizing procurement.

Triacs Selection Notes

Select this component for AC phase control circuits requiring robust high-temperature performance and sensitive gate drive compatibility. Consider the TO-252-3 package constraints for thermal management and PCB layout when integrating into motor or lighting control systems.

Triacs Part Context

This device belongs to the QJxx08xHx series of High Temperature Alternistor Triacs from Littelfuse. These components are engineered specifically for demanding AC switching environments where standard triacs may fail due to thermal stress or high commutation requirements.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic triac replacements may not match the specific Alternistor high commutation characteristics or sensitive gate quadrant requirements.
