Q4008LH4TP General Description

8 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays.Sensitivetype devices guarantee gate control in Quadrants I & IV needed for digital control circuitry.Standardtype devices normally operate in Quadrants I & III triggered from AC line.Alternistortype devices only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability.

Key Features

RoHS compliant
Glass — passivated junctions
Voltage capability up to 1000 V
Surge capability up to 100 A
Electrically isolated "L-Package" is UL-recognized for 2500Vrms
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

Application

Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls.
Typical applications are AC solid-state switches, light dimmers, power tools, home/brown goods and white goods appliances.
Alternistor Triacs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance.
Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
