Datasheet

COO (Country of Origin):: CN

4 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Sensitive type devices guarantee gate control in Quadrants I & IV needed for digital control circuitry.

Features & Benefits:

Glass – passivated junctions

Voltage capability up to 1000 V

Surge capability up to 55 A

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 of sine wave

Requires only a small gate activation pulse in each half-cycle

Applications:

Typical applications are AC solid-state switches, power tools, home/brown goods and white goods appliances.

Sensitive gate Triacs can be directly driven by microprocessor or popular opto-couplers/isolators.

Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
