TCR22-x Series
1.5 Amp Sensitive SCRs
1.5A SCRs
TCR22-x 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.
