Overview
The ACST1035-8FP is a medium current AC switch from the ACS/ACST family, built with Application Specific Discrete (A.S.D.) technology. It integrates a Triac structure with a high-voltage clamping device to absorb inductive turn-off energy and withstand line transients compliant with IEC 61000-4-5 standards. The device offers an extremely high static dV/dt immunity of 2 kV/µs minimum at a 150 °C junction temperature. Rated for 10 A RMS current and 800 V repetitive peak reverse voltage, it operates within a maximum junction temperature of 150 °C. The component is housed in an insulated TO-220FPAB package providing 1500 V RMS isolation, complying with UL standards and RoHS directives.
Feature Summary
- Integrates self overvoltage protection via internal high-voltage clamping
- Provides high static dV/dt immunity to prevent false triggering
- Features insulated tab for enhanced safety compliance
Applications
- Home appliance motor speed controllers
- Industrial systems requiring robust AC switching
- Inductive load driving applications
Procurement Notes
Verify the specific suffix '8FP' corresponds to the TO-220FPAB insulated package configuration. Confirm that the ordering part number matches the required insulation rating and thermal characteristics. Ensure compatibility with the intended PCB layout for the specified package type before finalizing procurement orders.
Selection Notes
Select this component when high commutation capability and overvoltage protection are required without external snubber circuits. It is suitable for applications demanding high static dV/dt immunity and operation at elevated junction temperatures up to 150 °C. Consider the insulated package requirement for safety isolation needs in mains-powered designs.
Part Context
The ACST1035-8FP belongs to the STMicroelectronics ACST power switch family, which utilizes A.S.D. technology to combine Triac functionality with integrated protection features. This series is designed to simplify system development by reducing the need for external protective components, thereby streamlining the design process for AC switching applications.
Replacement Considerations
Direct substitutes may include other STMicroelectronics ACST series devices with similar current and voltage ratings, such as the ACST1235-8FP, provided the package and insulation requirements are compatible. Verify electrical parameters and thermal performance before substitution.
