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
Q6012LTH1LED series is designed to meet low load current
characteristics typical in LED lighting applications.
By keeping holding current at 8mA maximum, this Quadrac
series is characterized and specified to perform best with
LED loads. The Q6012LTH1LED series is best suited for
LED dimming controls to obtain the lowest levels of light
output with a minimum probability of flickering.
Q6012LTH1LED series is offered in the industry standard
TO-220AB package with an isolated mounting tab that
makes it best suited for adding an external heat sink.
• As low as 8mA max
• UL recognized TO-220AB
• 110°C rated junction
• di/dt performance of
• QUADRAC version
includes intergrated DIAC
• Provides full control
of light out put at the
extreme low end of load
and active terminals
• Improves margin of safe
operation with less heat
• Enable survivability
of typically LED load
• Simplicity of circuit design
Excellent for AC switching and phase control applications
such as lighting and motor speed controls. Typical
applications are AC solid-state switches, light dimmers
with LED loads, small low current motor in power tools,
and low current motors in home/brown goods appliances.
Internally constructed isolated package is offered for ease
of heat sinking with highest isolation voltage.
