35 Amp Standard & 30 / 35 Amp Alternistor (High Commutation) Triacs
Qxx30xHx & Qxx35xx & Qxx35xHx Series
Description
30 Amp / 35 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.
Standard type devices normally operate in Quadrants I & III
triggered from AC line.
Alternistor type devices only operate in quadrants I, II, & III
and are used in circuits requiring high dv/dt capability.

Applications
Excellent for AC switching and phase control applications
such as heating, lighting, and motor speed controls.
Typical applications are AC solid-state switches, industrial
power tools, exercise equipment, white goods and
commercial 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.
