## **Features**
- Drive of low power high inductive or resistive loads like:
- Relay, valve, solenoid, dispenser
- Pump, fan, micro-motor
- Defrost heater
## **Description**
The ACS120 belongs to the AC line switch family. This high-performance switch circuit is able to control a load of up to 2 A.
The ACS switch embeds a high-voltage clamping structure to absorb the inductive turn-off energy and a gate level shifter driver to separate the digital controller from the main switch. It is triggered with a negative gate current flowing out of the gate pin.
- Blocking voltage: VDRM / VRRM = +/- 700 V
- Avalanche controlled: VCL typ. = 1100 V
- Nominal conducting current: IT(RMS) = 2 A
- Gate triggering current: IGT < 10 mA
- High noise immunity: static dV/dt > 500 V/µs
- Needs no more external protection snubber or varistor
- Enables equipment to meet IEC 61000-4-5
- Reduces component count up to 80%
- Interfaces directly with the micro controller
- Eliminates any gate kick back on the microcontroller
- Allows straightforward connection of several AC switches on same cooling pad

**AC line switch basic application**
**ACS120**
## **2 AC line switch basic application**
The ACS120 device is well adapted to washing machine, dishwasher, tumble drier, refrigerator, air-conditioning systems, and cookware. It has been designed especially to switch on and off low power loads such as solenoid, valve, relay, dispenser, micro-motor, pump, fan and defrost heaters.
This AC switch is triggered by a negative gate current flowing out of the gate pin G. It can be driven directly by the digital MCU through a resistor as shown on the typical application diagram.
Thanks to its thermal and turn-off commutation performance, the ACS120 switch can drive, with no additional turn-off snubber, an inductive load up to 2 A.

## **2.1 Protection against overvoltage: the best choice is ACS**
In comparison with standard Triacs the ACS120 is over-voltage self-protected, as specified by the new parameter VCL. This feature is useful in two operating conditions: in case of turnoff of very inductive load, and in case of surge voltage that can occur on the electrical network.

**AC line switch basic application**
## **2.2 High inductive load switch-off: turn-off overvoltage clamping**
With high inductive and low RMS current loads the rate of decrease of the current is very low. An overvoltage can occur when the gate current is removed and the OUT current is lower than IH.
As shown in _Figure 15 and Figure 16_ , at the end of the last conduction half-cycle, the load current decreases (1). The load current reaches the holding current level IH (2), and the ACS turns off (3). The water valve, as an inductive load (up to 15 H), reacts as a current generator and an overvoltage is created, which is clamped by the ACS (4). The current flows through the ACS avalanche and decreases linearly to zero. During this time, the voltage across the switch is limited to the clamping voltage VCL. The energy stored in the inductance of the load is dissipated in the clamping section that is designed for this purpose. When the energy has been dissipated, the ACS voltage falls back to the mains voltage value (230 V rms, 50 Hz) (5).

## **2.3 Alternating current mains transient voltage ruggedness**
The ACS120 switch is able to withstand safely the AC mains transients either by clamping the low energy spikes or by breaking-over when subjected to high energy shocks, even with high turn-on current rises. The test circuit shown in _Figure 17_ is representative of the final ACS120 application, and is also used to test the AC switch according to the IEC 61000-4-5 standard conditions. Thanks to the load limiting the current, the ACS120 switch withstands the voltage spikes up to 2 kV above the peak mains voltage. The protection is based on an overvoltage crowbar technology. Actually, the ACS120 breaks over safely as shown in _Figure 18_ . The ACS120 recovers its blocking voltage capability after the surge (switch-off back at the next zero crossing of the current). Such non-repetitive tests can be done 10 times on each AC mains 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.
