8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs
8.0A TRIACs
Lxx08xx & Qxx08xx & Qxx08xHx Series
Main Features
Description
8 Amp bi-directional solid state switch series is designed
for AC switching and phase control applications such as
motor speed and temperature modulation controls, lighting
controls, and static switching relays.
Sensitive type devices guarantee gate control in Quadrants
I & IV needed for digital control circuitry.
Standard type devices normally operate in Quadrants I & III
triggered from AC line.
Alternistor type devices only operate in quadrants I, II, & III
and are used in circuits requiring high dv/dt capability.

rating. Other ways to ensure long life for a power discrete
semiconductor are proper heat sinking and selection of
voltage ratings for worst case conditions. Overheating,
overvoltage (including dv/dt), and surge currents are
the main killers of semiconductors. Correct mounting,
soldering, and forming of the leads also help protect
against component damage.
