Description
Q6008LH1LED series is designed to meet low load current
characteristics typical in LED lighting applications.
By keeping holding current at 6mA maximum, this Triac
series is characterized and specified to perform best with
LED loads. The Q6008LH1LED series is best suited for LED
dimming controls to obtain the lowest levels of light output
with a minimum probability of flickering.
Q6008LH1LED 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.
Features
• As low as 6mA max
holding current
Benefits
• Provides full control
of light out put at the
extreme low end of load
conditions.
• UL recognized TO-220AB
package
• 2500V

Q6008LH1LED Series
Applications
Excellent for AC switching and phase control applications
G
such as heating, lighting, and motor speed controls.
Typical applications are AC solid-state switches, lighting
controls with LED lamp loads, small low current motor in
power tools, and low current motors in home/brown goods
appliances.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
