Product types
ST AC switch insulated driver (STSID)
The STSID insulated thyristor gate drivers are engineered to meet diverse industrial, consumer, and renewable energy application requirements. The STSID family brings superior performance and reliability, with a range of benefits that can optimize power management systems.
They are available in a miniature LGA package, enabling automatic surface mounting and low-profile assembly for compact designs.
Automatic voltage switches (AVS)
Automatic voltage switches consist of a dedicated driver and a triac for 120/240 V bivoltage applications. The driver features 50/60 Hz compatibility, a triggering pulse train for the triac, a parasitic filter, and low power consumption. The triac has a maximum voltage specified at 600 V and a maximum current up to 12 A.
AVS devices are available in DIP 8 packages for the driver and TO-220 and TO-220I packages for the triacs.
Benefits
- Best-in-class EMI & EMC: improve noise immunity resistance for stable operation, even in environments with high electromagnetic interference. Lowering the switching noise during zero cross significantly reduces input line filtering requirements.
- Dual switching support: zero-cross switching is supported with minimal external components, offering additional flexibility without paying a premium for dedicated alternatives. Load state detection can be implemented by monitoring the STSID current supply.
- Compact design: small packages save PCB space for more efficient and streamlined designs.
- Energy efficiency: advanced technology that maximizes efficiency without compromising performance.
- High reliability: a robust and dependable solution that ensures consistent performance across a wide range of applications.
