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.
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.
600 V, 150°C 6H high-temperature Triacs
With high inrush and transient current capability, ST's 6H high-temperature (600 V) Triacs are designed for AC power equipment including motors, high-end home appliances, heating units, coffee machines and food processors.
The 10 to 50 mA gate current versions make it easier to drive with an MCU port, while still ensuring voltage transient immunity at a standardized 6 kV IEC61000-4-4 level.
Able to control transient currents up to 4 times its nominal IT(RMS), designers can use smaller silicon triacs for the same job, a particularly valuable feature on inductive loads. Or you can reduce the heatsink size using the enhanced 150°C junction temperature (TJ) for higher thermal headroom for smaller, more robust appliances.
