8H Triacs maximize current density or reduce heatsink size by 50%
Designed to run in very hot, confined environments and improve system reliability in adverse power grid environments, our 8H series of high-voltage Triacs are ideal for use as an AC power switch for water heaters, industrial automation, HVAC, roller shutters and building lighting control units.
Key features of 8H Triacs
- Maximize AC system power density
- Reduce system size
- Increase functional safety
- Robust dynamic turn-off commutation at high-temperature
- High noise immunity at 150°C – static dV/dt
- Reduce application size (heatsink) allowing more features
- Works directly on the grid up to 400V AC
- Full range available in multiple packages: TO-220, TO-220 Ins,and D2PAK
