QJ6008LH4TP

Triacs Overview

The Littelfuse QJ6008LH4TP 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 on-state currents of 83 A or 100 A depending on the specific test condition. The device has a rated repetitive peak 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 suitable for demanding thermal environments
• Bidirectional switching functionality for AC power control
• Robust construction in a standard through-hole package

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the ordering code matches the specific lot marking requirements for your assembly process. Cross-reference the component with Littelfuse documentation to validate RoHS compliance status and lead time availability from authorized distributors.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required for AC switching. Consider the TO-220AB package for adequate heat dissipation without additional active cooling. Verify that the gate trigger current of 35 mA is compatible with the driving circuitry capabilities.

Triacs Part Context

This part belongs to the Qxx06xH series of high-temperature TRIACs from Littelfuse. These devices are engineered for reliability in industrial and commercial power control applications where standard components may fail due to thermal stress. The Alternistor technology provides a cost-effective alternative to discrete SCR pairs.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic TRIAC replacements must match the 8 A It RMS, 600 V VDRM, and TO-220AB-3 package constraints. Verify gate sensitivity and thermal resistance parameters before implementation.
