Online simulator speeds thyristor, AC switch selection

30 March 2022 Design Automation

To quickly find the thyristor or AC switch that best fits their design, engineers can use STMicroelectronics’ AC Switch Simulator online tool by simply entering the main I/O and gate parameters.

To refine the search and help improve the design, this user-friendly tool lets the user calculate the junction temperature with a specified load RMS current and ambient temperature, select the appropriate heatsink and get an estimate of their design’s voltage blocking capability. Packages, isolated versions, current ratings and alternative voltages can be ironed out in a single session and the AC switching circuit suggestions can be delivered with an instant options check.

Available in English and Chinese, its responsive web design presents interactive schematics and BOM tools as well as thermal analysis and blocking capability simulators on any desktop, smartphone or tablet computer.

AC Switch Simulator can be accessed at https://eds.st.com/acswitch/#/
