Description
Available in through-hole, the T12T series of
Triacs can be used as on/off or phase angle
control function in general purpose AC switching
where high commutation capability is required.
This series can be designed in many value
sensitive appliances thanks to the parameters
guidance provided in the following pages.
Provides insulation rated at 2500 V rms
(TO-220AB insulated package).
