STSID140-12 [STMicroelectronics]

Integrated insulated gate driver for AC switch SCRs or Triacs. Its insulated voltage up to 1.25 kVRMS gives functional insulation to drive any thyristor in industrial application.

The STSID140-12 is a 40 mA output gate driver, allowing to design large range of thyristors for industrial AC motor control, or suitable for inrush current management in AC/DC application.

A high reliability solution, the AC switch-insulated driver is able to ensure high load current switching making the plug and play interface between MCU and SCR/Triac.
