Description
Specifically designed to operate at 150° C, the
new 20 A T2035H Triacs provide an enhanced
performance in terms of power loss and thermal
dissipation. This facilitates the optimization of
heatsink dimensioning, leading to improved space
and cost effectiveness when compared to electro-
mechanical solutions.
Based on ST Snubberless™ technology, the
T2035H series offers high commutation switching
capabilities and high noise immunity levels on the
full range of T
j
.
The T2035H series facilitates the optimization of
the control of universal motors and inductive
loads found in appliances such as vacuum
cleaners, and washing machines.
