Littelfuse Sxx04xSx User Manual
Sxx04xSx Series
Teccor® brand Thyristors
4 Amp Sensitive SCRs
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.
