65 / 70 Amp Standard SCRs
Sxx65x & Sxx70x Series
®
Description
Excellent unidirectional switches for phase control
applications such as heating and motor speed controls.
Standard phase control SCRs are triggered with few
milliamperes of current at less than 1.5V potential.
Features & Benefits
• RoHS compliant
• Voltage capability up
to 1000 V
• Glass – passivated
junctions
