SURFACE MOUNT TRIAC
This series of TRIACs uses a high performance
PNPN technology.
These devices are intended for AC control
applications using surface mount technology.
The high commutation performances combined with
high sensitivity, make them perfect in all applications
like solid state relays, home appliances, power tools,
small motor drives...
