T12T
Entry level Snubberless™, logic level and standard 12 A Triacs
Features
■ Medium current Triac
■ High static and dynamic commutation
■ Low thermal resistance with clip bonding
■ Packages is RoHS (2002/95/EC) compliant
■ 600 V VRM
Applications
■ Entry level and value sensitive application
■ General purpose ac line load switching
■ Motor control circuits in power tools
■ Small home appliances, lighting
■ Inrush current limiting circuits
■ Overvoltage crowbar protection
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.

Initially planned for power Tools (T series)
equipment, this series can be designed-in 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).
