Q6008R567

Triacs Overview

The Littelfuse Q6008R567 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 pulse width. Leakage current in the off-state is limited to 10 uA at VDRM.

Triacs Feature Summary

• High commutation performance suitable for extremely inductive loads without requiring external snubber circuits
• Sensitive gate structure enabling reliable triggering from digital control circuitry in quadrants I and IV
• Glass-passivated junctions providing robust protection against environmental stress and voltage transients

Triacs Applications

• AC solid-state switches and static switching relays
• Lighting controls and light dimmers
• Motor speed modulation and temperature control systems
• Home appliances including white goods and brown goods

Triacs Procurement Notes

Verify the specific suffix R567 against official Littelfuse documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS and REACH requirements for your region. Confirm lead times and minimum order quantities directly with authorized distributors as these vary by supply chain status.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required for AC phase control. The sensitive gate characteristic makes it suitable for direct interface with microcontrollers or logic circuits. Consider thermal management requirements based on the 1.6 V on-state voltage drop and expected load currents during continuous operation.

Triacs Part Context

This part belongs to the Qxx08xHx series of 8 Amp Triacs manufactured by Littelfuse under the Teccor brand. The series includes sensitive, standard, and Alternistor types designed for various AC switching needs. The Q6008R567 specifically utilizes the high commutation Alternistor technology for improved performance in inductive environments.

Triacs Replacement Considerations

Compatible substitutes within the same family include Q6008NH4RP and Q6008DH4RP. Verify pinout compatibility and exact electrical ratings before substitution. Alternative packages such as TO-252 or SMTO-263 may require PCB layout adjustments.
