Objective specification
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.

This data sheet contains target or goal specifications for product development.
This data sheet contains final product specifications.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later.
Limiting values are given in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and
operation of the device at these or at any other conditions above those given in the Characteristics sections of
this specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
