Q4008LH4

LITTELFUSE  Q4008LH4  三端双向可控硅, 400 V, 35 mA, 500 mW, 1.3 V, TO-220AB, 83 A

The 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
