Q6008LH1LED Series
Q6008LH1LED Series
Main Features
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.

Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment will go a long way
toward extending the operating life of the Thyristor. Good
design practice should limit the maximum continuous
current through the main terminals to 75% of the device
rating. Other ways to ensure long life for a power discrete
semiconductor are proper heat sinking and selection of
voltage ratings for worst case conditions. Overheating,
overvoltage (including dv/dt), and surge currents are
the main killers of semiconductors. Correct mounting,
soldering, and forming of the leads also help protect
against component damage.
