• Inrush current limiting circuits
• Overvoltage crowbar protection
Description
The T2535T-8I Triac in TO-220AB package can be used for the on/off or phase angle control function in general purpose AC switching.
Based on the ST Snubberless technology, it offers higher specified turn-off commutation and noise immunity levels up to 150 °C.
The T2535T-8I safely optimizes the control of the motors and heaters loads for the most constraining home appliances environments.
By using an internal ceramic pad, the TO-220AB insulated package provides a UL recognized component isolation, rated at 2500 V
RMS
.
