1 Amp Sensitive & Standard Triacs

Lx01Ex & LxNx & Qx01Ex & QxNx Series

Description

1 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.

Sensitive type devices guarantee gate control in Quadrants
I & IV needed for digital control circuitry.

Standard type devices normally operate in Quadrants I & III
triggered from AC line.

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.
