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.
