Thyristors

Thyristors include SCRs, TRIACs, fast thyristors and phase-control thyristors for controlled rectification, AC power control and high-power switching. They are widely used in soft starters, industrial heating systems, welding equipment, controlled rectifiers, motor speed control, battery chargers and AC voltage regulators. Selection usually depends on repetitive peak off-state voltage, average on-state current, surge current, gate trigger requirements, commutation characteristics, package and thermal conditions. SemiVant supports replacement and hard-to-find thyristor sourcing.
