4 Amp Sensitive SCRs
Sxx04xSx Series
Description
Excellent unidirectional switches for phase control
applications such as heating and motor speed controls.
Sensitive gate SCRs are easily triggered with microAmps
of current as furnished by sense coils, proximity switches,
and microprocessors.

design practice should limit the maximum continuous
current through the main terminals to 75% of the device
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.
