40 Amp Alternistor (High Commutation) and Standard Triacs
RoHS
Qxx40xx Series
Description
The 40 Amp bi-directional solid state switch series is
designed for AC switching and phase control applications
such as motor speed, temperature modulation controls,
lighting controls, and static switching relays.
Alternistor type components only operate in quadrants I, II,
& III and are used in circuits requiring high dv/dt capability.
Standard type devices operate in quadrants I,II,III & I

Design Considerations
Careful selection of the correct component 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 component 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.
