Description
Silicon rectifiers that are excellent for DC phase control
applications with motor loads.
Isolated mounting tab allows for use in circuits with
common anode or common cathode connections.
Features & Benefits
• RoHS Compliant
• Glass – passivated
junctions
• Voltage capability up to
1000 V
• Surge capability up to
350 A
Applications
Typical applications are AC to DC solid-state switches for
industrial power tools, exercise equipment, white goods,
and commercial appliances.
Internally constructed isolated package is offered for ease
of heat sinking with highest isolation voltage.
