40 Amp High Temperature Alternistor Triacs Description The 40 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed, temperature modulation controls, lighting controls, and static switching relays. Alternistor type components only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability. Standard type devices operate in quadrants I,II,III & IV Agency Recognitions Applications Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls. Typical applications are AC solid-state switches, industrial power tools, exercise equipment, white goods and commercial appliances. Alternistor Triacs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage. Specifications are subject to change without notice. Revised: 08/15/19

Reflow Condition Design Considerations Environmental Specifications Careful selection of the correct component for the application's operating parameters and environment will go a long way toward extending the operating life of the Thyristor. Good design practice should limit the maximum continuous current through the main terminals to 75% of the component rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers...
