Q4008LH4 Datasheet PDF - Littelfuse

●The Q4008LH4 is a 8A Alternistor TRIAC designed for AC switching and phase control applications. This Teccor® Thyristor only operates in quadrants I, II and III. It is used in circuits requiring high dV/dt capability.

● High commutation

● Glass-passivated junctions

● Surge capability up to 100A

● 400V Voltage rating

● Solid-state switching eliminates arcing or contact bounce that create voltage transients

● No contacts to wear out from reaction of switching events

● Restricted (or limited) RFI generation, depending on activation point of sine wave

● Requires only a small gate activation pulse in each half-cycle
