25A TRIACS
DESCRIPTION

The UTC BTB25 is a 25A triacs which can be operated in 4
quadrants, it uses UTC’s advanced technology to provide
customers with high commutation performances.
The UTC BTB25 is suitable for AC switching application and
phase control application such as fan speed and temperature
modulation control, lighting control and static switching relay, either
in through-hole or surface-mount packages.
