Description:
A triac is a solid state silicon
AC switch which may be gate
triggered from an off-state to an
on-state for either polarity of
applied voltage.
Features:
Glass Passivation
Applications:
AC Switch
Ordering Information:
Example: Select the complete
seven or eight digit part number
you desire from the table - i.e.
BCR1AM-8 is a 400 Volt,
