MAIN FEATURES :
Specifically developed for use in high temperature
and harsh environments, the T2550H-600T triac is
perfectly suited to driving heating elements found
in hot appliances such as ovens, electric ranges or
halogen ranges.
The T2550H-600T, which is specified for use in
temperature up to Tj = 150 C, offers the additional
benefit of improved thermal resistance (1 C/W).
Thanks to this feature, heatsink dimensionning can
be optimized to suit typical conditions in such
applications. The devices surge features, which
have proven to be highly performing, ensure safe
operation under peak inrush current conditions -
for example, in halogen ranges.
