Description
The Quadrac is an internally triggered Triac designed for
AC switching and phase control applications. It is a Triac
and DIAC in a single package, which saves user expense
by eliminating the need for separate Triac and DIAC
components.
Standard type devices normally operate in Quadrants I & III
triggered from AC line.
Alternistor type Quadracs are used in circuits requiring high
dv/dt capability.
Features & Benefits
• RoHS Compliant
• Glass – passivated
junctions
• Voltage capability up to
600 V
• Surge capability up to
200 A
Applications
Excellent for AC switching and phase control applications
such as lighting and heating. Typical applications are AC
solid-state switches, light dimmers, power tools, home/
brown goods and white goods appliances.
Alternistor Quadracs (no snubber required) are used in
applications with extremely inductive loads requiring
highest commutation performance.
Internally constructed isolated package is offered for ease
of heat sinking with highest isolation voltage.
