10 Amp Sensitive & Standard SCRs
Sxx10xSx & Sxx10x Series
Description
Excellent unidirectional switches for phase control and
general switching 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.
Standard phase control SCRs are triggered with few
milliamperes of current at less than 1.5V potential.

Typical applications are capacitive discharge systems for
strobe lights, nailers, staplers and gas engine ignition. Also
controls for power tools, home/brown goods and white
goods appliances.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
