800 V, 150°C 8H high-temperature Triacs

Designed for thermal-intensive heavy-duty applications, ST's 8H Triacs are high-voltage (800 V) switches with full power line capability and immunity for driving tough loads in increasingly compact modules thanks to their no-compromise rating at temperatures up to 150°C.

8H Triacs

From 230 V single-phase to 400 V three-phase supplies, ST's 8H Triacs are designed for use as an AC mains switch for water heaters, industrial automation, HVAC, roller shutters and building lighting control units. With snubberless™ voltage transient immunity, these triacs are well adapted to handle the EMI disturbance and unstable mains environments typical of these AC network connected applications.

Thanks to its low and stable leakage currents and transient current switching capability twice the nominal current, the 8 to 30 A range of the 8H Triacs ensures excellent switching capabilities. Available in a ceramic-insulated TO-220AB package, D2PAK or classical TO-220AB packages, 8H Triacs also let designers reduce the size of heatsinks in their solutions thanks to the maximum 150°C junction temperature (TJ). A silicon semiconductor and solid-state solution, this series offers certain advantages over traditional relays including its sparkless and non-aging switch characteristics.
