Q6008R5

Triacs Overview

The Littelfuse Q6008R5 is a Triac component belonging to the Qxx08xHx series, designed for AC switching and phase control applications. It features an RMS on-state current (It RMS) of 8 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current (Ih) of 35 mA, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 35 mA. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 83 A or 100 A depending on the pulse width. Leakage current in the off-state is limited to 10 uA at VDRM.

Triacs Feature Summary

• Sensitive gate type operation suitable for digital control circuitry requiring triggering in quadrants I and IV.
• High surge current capability up to 100 A for robust performance during transient events.
• Glass-passivated junctions provide enhanced reliability and protection against environmental factors.

Triacs Applications

• AC solid-state switches
• Lighting controls and light dimmers
• Motor speed modulation controls

Triacs Procurement Notes

Verify the exact suffix designation when ordering, as variations such as Q6008R552 indicate specific package configurations like TO-220AB. Confirm RoHS compliance status through official Littelfuse documentation prior to integration. Ensure that the selected variant matches the required thermal management and mounting style for the target application design.

Triacs Selection Notes

Select this component for general-purpose AC phase control where sensitive gate drive compatibility is required. The 600 V rating suits standard mains voltage applications. Consider thermal dissipation requirements given the 8 A RMS rating. Verify that the 35 mA gate trigger current aligns with the driving circuit's output capabilities for reliable turn-on across all operating temperatures.

Triacs Part Context

This part belongs to the Qxx08xHx series of Triacs from Littelfuse, which are engineered for high commutation performance. The series includes variants with different packaging options such as TO-220AB and surface-mount packages. These devices are widely used in consumer appliances and industrial controls due to their balance of current handling and gate sensitivity.

Triacs Replacement Considerations

Direct substitutes may include other 8 A, 600 V sensitive gate Triacs from Littelfuse or competitors, provided they match the pinout and electrical characteristics. Verify that replacement parts maintain the same gate trigger specifications and thermal resistance values to ensure circuit compatibility without redesign.
