4 Amp Sensitive SCRs
Sxx04xSx Series
Description
RoHS
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.
Features & Benefits
• RoHS compliant
• Glass – passivated
junctions
• Voltage capability up
to 600 V
• Surge capability up to
30 A
