DESCRIPTION
The UTC BTB12 is a 12A triacs which can be operated in 4
quadrants, it uses UTC’s advanced technology to provide customers
with high commutation performances.
The UTC BTB12 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.
