T16T
Snubberless™, logic level and standard 16 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
■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 T16T 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).
