Littelfuse Inc. TRIAC Alternistor, Q4006LH4, offers robust control for AC power switching applications. This single-phase, snubberless TRIAC is rated for 400V off-state voltage and an RMS on-state current of 6A. Key parameters include a maximum gate trigger current (Igt) of 35mA and a maximum holding current (Ih) of 35mA, with a gate trigger voltage (Vgt) not exceeding 1.3V. Its non-repetitive surge current handling is 80A at 50Hz and 85A at 60Hz. Designed for through-hole mounting, the Q4006LH4 features a TO-220 isolated tab package, facilitating efficient thermal management. Operating across a temperature range of -40°C to 125°C (TJ), this component is suitable for demanding environments, including industrial controls, motor speed regulation, and power supply applications where reliable AC switching is critical.
