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
• Glass – passivated
junctions
• Voltage capability up
to 1000 V
• Surge capability up to
350 A
Applications
Typical applications are AC solid-state switches, industrial
power tools, exercise equipment, white goods and
commercial appliances.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
