STMicroelectronics ACS120-7SH Overvoltage Protected AC Switch
The ACS120-7SH is a state-of-the-art AC switch developed by STMicroelectronics, designed to deliver exceptional performance in a wide range of applications. This device is part of the ACS switch family, which is renowned for its integration of the overvoltage protected high voltage switch functionality and system-in-package expertise that STMicroelectronics is known for.
This robust component is built to withstand transient overvoltages up to 800V, ensuring reliability and safety in the event of unexpected voltage spikes. It is particularly well-suited for home appliances and industrial systems where overvoltage protection is critical. The ACS120-7SH can handle a load current of up to 1 A, making it versatile for controlling various resistive and inductive loads.
The switch is housed in a compact SMD package, which allows for a reduction in PCB space and is beneficial for designs where space is at a premium. Its high noise immunity and easy driving make it a user-friendly option for designers, simplifying the implementation process and reducing the need for additional components.
Key features of the ACS120-7SH include:
- On-state rms current, I<sub>T(RMS), up to 1 A
- Repetitive peak off-state voltage, V<sub>DRM/V<sub>RRM, of 600 V
- Static dV/dt of 250 V/μs as a minimum
- High noise immunity against false turn-on
- ECOPACK®2 compliant component for sustainable environmental regulations
The device also includes an integrated overvoltage protection feature, which eliminates the need for external varistors in many applications, thereby saving on BOM costs and simplifying the circuit design. Additionally, the ACS120-7SH is characterized by a low gate trigger current, which allows direct interfacing with microcontrollers and other logic-level devices.
With its combination of features, the ACS120-7SH from STMicroelectronics represents a reliable and efficient solution for designers looking to incorporate AC switching capabilities into their applications with the added benefit of overvoltage protection. Its robustness, ease of use, and integration of protection features make it a smart choice for a variety of electrical designs.
