Description
Available in through-hole full pack package, the
T835T-8FP Triac can be used for the on/off or
phase angle control function in general purpose
AC switching where high commutation capability
is required. This device can be used without a
snubber circuit when the limits defined in this
datasheet are respected
Provides UL certified insulation rated at 2 kV.
