ST’s T-series Triacs are designed for the ever increasing number of AC loads in appliance control. These AC appliance switches meet both the immunity and high-commutation needs, offering a cost-effective solution.
For this series, both immunity (dV/dt) and commutation capability (dI/dt)c are specified, as well as the low gate current. This last parameter is key, as it helps optimize the power supply and allows direct drive capability through a single resistance between the microcontroller and the Triac, for all 10 mA gate types.
The trade-off of surge current (I TSM) versus immunity and commutation capability is improved. This is one step ahead of the usual offer, and a unique range in the market.

New T-Series Triacs changes the game with increased number of AC loads

Designed for use as on/off or phase angle function controllers in general-purpose AC switching, the T1635T-8I  can be used without a snubber (R + C networks).

Part of ST's new T-series, this Snubberless™ 16 A Triac is able to handle the increasing number of AC loads in appliance control applications. Available in a ceramic-insulated TO-220AB package, it is a cost-effective solution with excellent trade-off of surge current versus immunity and commutation.

6 to 20 A T-series Triacs with 800 V capability are now available in a D²PAK package, providing improved EMC immunity and commutation for a wider range of loads.
