Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment will go a long
way toward extending the operating life of the Thyristor.
Overheating and surge currents are the main killers of
SIDACs. Correct mounting, soldering, and forming of the
leads also help protect against component damage.
