T8T
Snubberless™, logic level and standard 8 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
■ UL certified (ref. file E81734)
Applications
■ 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 T8T 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 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).
