STMicroelectronics – ACST series combine robustness, reliability and straightforward design
The home appliance industry is shifting to electronic control worldwide. Together with this trend, electronics can now handle AC mains constraints where high voltage robustness, and surge and transient voltage compatibility are the key challenges.
ST has introduced a new 800 V ACST series to control the numerous AC loads necessary for appliances. These AC switches meet the requirements for system reliability and compactness.
They are the perfect solution to replace relays, in refrigeration compressor control, for example, where they are connected to the AC mains 24 hours a day and are directly controlled by a microcontroller.
KEY FEATURES
- Auto protected against AC line overvoltage surges
- 150 °C operating temperature range
- Symmetric blocking voltage at 800 V
- 2 to 16 A current range
- 2 ranges of IGT
- 35 mA high immunity series (dV/dt ≥ 2000 V/μs)
- 10 mA sensitive series defined at TJ = 125 °C
TARGET APPLICATIONS
- Compressor control
- Refrigeration
- Air conditioning
- Drum motor control
- Washing machines
- Dryers
- Heating element in Printers
- Medium-power motor and heater control in industrial systems
