Suited to industrial, personal care, smart-home, and smart-building applications, these Triacs leverage ST’s latest Snubberless high-temperature technology to achieve outstanding ruggedness. With low on-state voltage (VTM), which ensures high operating efficiency and minimises self-heating, the devices also have low leakage current that is stable over time to reduce standby losses. In addition, robust dynamic performance with high critical turn-off current slope prevents unwanted commutation.
Capable of safely driving inductive loads, the 8H Triacs let designers create rugged and efficient controls for HVAC systems, AC-motor drives, water heaters, room heaters, lighting systems, home appliances, and smart AC plugs.
The complete 8H family spans current ratings from 8A to 30A. The peak off-state voltage of 800V ensures robust performance in AC-line-powered applications including 3-phase equipment operating from up to 400V RMS.
The devices benefit from high noise immunity and can withstand voltage fast transients up to 6kV and voltage gradient (dV/dt) up to 2000V/µs across the full junction-temperature range.
