Features &Amp; Benefits
• RoHS Compliant
• Glass – passivated junctions
• Voltage capability up to 1000 V
• Surge capability up to 200 A
• Electrically isolated “L-Package” is UL recognized for 2500Vrms
• Solid-state switching eliminates arcing or contact bounce that create voltage transients
• No contacts to wear out from reaction of switching events
• Restricted (or limited) RFI generation, depending on activation point in sine wave
• Requires only a small gate activation pulse in each half-cycle

Applications
   Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls.
   Typical applications are AC solid-state switches, light dimmers, Power tools, lawn care equipment, home/brown goods and white goods appliances.
   Alternistor Triacs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance.
