Q6008R4TP

Triacs Overview

The Littelfuse Q6008R4TP is a high-temperature Alternistor TRIAC designed for robust power control applications. It features an RMS on-state current (It RMS) of 8 A and supports non-repetitive peak on-state currents of 83 A or 100 A depending on the specific test condition. The device has a rated repetitive off-state voltage (VDRM) of 600 V, with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include an on-state voltage of 1.5 V, 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. It operates within a temperature range of -40 C to +150 C and is housed in a TO-220AB-3 through-hole package.

Triacs Feature Summary

• High-temperature capability up to 150 C for demanding environments
• Robust 8 A RMS current handling in a standard TO-220AB-3 package
• Low gate trigger requirements for efficient drive circuitry

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay designs requiring high thermal stability
• Power regulation circuits for heating elements

Triacs Procurement Notes

Verify the exact suffix against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure the ordering code matches the required packaging format. Cross-reference the specific lot traceability requirements with the supplier before finalizing the purchase order.

Triacs Selection Notes

Select this component when high junction temperature operation is critical. Compare the 600 V rating against system voltage spikes. Verify that the 8 A RMS current meets the load requirements while accounting for derating curves at elevated ambient temperatures.

Triacs Part Context

This part belongs to the Littelfuse Qxx08xH series of Alternistor TRIACs. These devices are engineered for high reliability and thermal performance compared to standard TRIACs. The series is commonly used in industrial and commercial power control applications where long-term stability under stress is required.

Triacs Replacement Considerations

Check for direct replacements within the Q6008 family, such as Q6008L5TP or Q6008LTTP, noting differences in package type and temperature ratings. Verify compatibility with existing heatsinking and gate drive circuits when substituting.
