The TPDVxx25 series uses high performance alternistor technology, featuring very high commutation levels and high surge current capability. These devices are well adapted to power control for inductive and resistive loads (motor, transformer, etc.), especially in three-phase power grid. Targeted three-phase applications include heating systems, motor starters, and induction motor speed control (especially for fans).
This document provides technical specifications for the TPDVxx25 series of 25 A high voltage Triacs from STMicroelectronics. These devices utilize high performance alternistor technology and are designed for power control of inductive and resistive loads, particularly in three-phase power grid applications such as heating systems, motor starters, and induction motor speed control.
