25 Amp Standard & Alternistor (High Commutation) Triacs
Qxx25xx & Qxx25xHx Series
RoHS
Description
This 25 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.
Standard alternistor triac components operate with inphase signals in Quadrants I or III and ONLY unipolar
negative gate pulses for Quadrant II or III. The alternistor
triac will not operate in Quadrant IV.

Typical applications are AC solid-state switches, industrial
power tools, exercise equipment, white goods and
commercial appliances.
Alternistor Triacs (no snubber required) are used in
applications with high inductive loads requiring the highest
commutation performance.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.

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 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.
