Specifically designed for use in high temperature
environment (found in hot appliances such as
cookers, ovens, hobs, electric heaters, coffee
machines...), the new 25 A T2550H triacs provide
an enhanced performance in terms of power loss
and thermal dissipation. This allows for
T0-220AB
T2550H-600TRG
optimization of the heatsinking dimensioning,
leading to space and cost effectivness when
compared to electro-mechanical solutions.
Order code
Based on ST snubberless technology, they offer
high commutation switching capabilities and high
noise immunity levels. And, thanks to their clip
assembly technique, they provide a superior
performance in surge current handling.
