Technical content

Features

■ Medium current TRIAC ■ High static and dynamic commutation ■ Low thermal resistance with clip bonding ■ Packages is RoHS (2002/95/EC) compliant ■ VRM = 600 V ■ Insulated packaged rated at 2500 V rms

Applications

■ Entry-level and value-sensitive applications ■ 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 used in many value sensitive appliances thanks to the guidance on parameters provided in the following pages.
