Triacs
BT138F series
GENERAL DESCRIPTION
Glass passivated triacs in a full pack
plastic envelope, intended for use in
applications
requiring
high
bidirectional transient and blocking
voltage capability and high thermal
cycling
performance.
Typical
applications include motor control,
industrial and domestic lighting,
heating and static switching.

Although not recommended, off-state voltages up to 800V may be applied without damage, but the triac may
switch to the on-state. The rate of rise of current should not exceed 15 A/µs.
