Three quadrant triacs
guaranteed commutation
GENERAL DESCRIPTION
Passivated guaranteed commutation
triacs in a plastic envelope suitable for
surface mounting, intended for use in
motor control circuits or with other highly
inductive loads. These devices balance
the requirements of commutation
performance and gate sensitivity. The
"sensitive gate" E series and "logic level"
D series are intended for interfacing with
low power drivers, including micro
controllers.

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.
