BT137X series
GENERAL DESCRIPTION
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 6 A/μs.
