(application specific discrete) technology. This high performance device is suited to home appliances or industrial systems, and drives loads up to 6 A. This ACST6 switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standards. The ACST610 needs only low gate current to be activated (IGT < 10 mA) and still shows a high noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test). - Triac with overvoltage protection - Low IGT (< 10 mA) - TO-220FPAB insulated package: - complies with UL standards (file ref: E81734) - insulation voltage: 2000 VRMS **Table 1.

Thanks to its thermal and turn off commutation performances, the ACST6 switch is able to drive an inductive load up to 6 A with no turn off additional snubber. It also provides high thermal performances in static and transient modes such as the compressor inrush current or high torque operating conditions of an AC motor. Thanks to its low gate triggering current level, the ACST6 can be driven directly by an MCU through a simple gate resistor as shown _Figure 16_ and _Figure 17_ . **Figure 16.

The ACST6 switch can safely withstand AC line transient voltages either by clamping the low energy spikes, such as inductive spikes at switch off, or by switching to the on state (for less than 10 ms) to dissipate higher energy shocks through the load. This safety feature works even with high turn-on current ramp up. The test circuit of _Figure 18_ represents the ACST6 application, and is used to stress the ACST switch according to the IEC 61000-4-5 standard conditions. With the additional effect of the load which is limiting the current, the ACST switch withstands the voltage spikes up to 2 kV on top of the peak line voltage. The protection is based on an overvoltage crowbar technology. The ACST6 folds back safely to the on state as shown in _Figure 19_ . The ACST6 recovers its blocking voltage capability after the surge and the next zero current crossing. Such a non repetitive test can be done at least 10 times on each AC line voltage polarity.

STMicroelectronics is a global leader in the semiconductor industry, recognized for developing highly integrated, energy-efficient solutions that power modern electronics. With a strong focus on innovation, ST provides a comprehensive portfolio of microelectronics that address the demanding requirements of industrial, automotive, communications, and consumer applications. Our extensive selection of STMicroelectronics components is built around a robust lineup of discrete semiconductors and circuit protection devices. We offer a wide variety of single MOSFETs, Schottky diodes, and fast and ultrafast recovery rectifier diodes, designed to deliver exceptional efficiency and thermal performance in power management and conversion systems. For robust circuit protection, our inventory features hundreds of transient voltage suppressors and TVS diodes that safeguard sensitive electronic components against destructive voltage spikes. In addition to core power discretes like TRIACs, SCRs, bipolar transistors, and single IGBTs, our STMicroelectronics range includes specialized integrated passive filters and MEMS sensors. Furthermore, ST offers advanced integrated passive devices, such as baluns and RF filters, which utilize high-quality monolithic RF IPD processes on glass or high-resistance silicon substrates. These components provide competitive cost structures, reduced power losses, and simplified RFIC-to-antenna matching, ensuring optimal system performance and delivering the reliability required for next-generation wireless and power designs.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
