ACS108-6, AC Line Switch with Crowbar Protection, TO-92 Package

The ACS108-6 is part of STMicroelectronics’ ACS™ family of AC switches, optimized for driving low-power inductive or resistive loads such as solenoids, pumps, or relays. It features a unique crowbar structure that provides superior protection against overvoltage conditions without requiring external components. With a gate trigger current of just 10 mA and static dV/dt immunity of over 500 V/μs, it can be safely controlled directly by digital logic or microcontrollers.

Key Features:

• AC Line Control Switch: Designed for ON/OFF control of AC appliances and inductive loads up to 0.8A.
• Crowbar Overvoltage Protection: Integrated protection clamps surges safely, eliminating the need for external snubbers or varistors.
• Logic-Level Gate Drive: Directly interfaces with microcontrollers (10mA gate trigger).
• High Noise Immunity: Static dV/dt exceeds 500 V/μs, ensuring robust operation in noisy environments.
• Compact TO-92 Package: Simple 3-pin design, ideal for low-profile or PCB-mounted systems.
• IEC 61000-4-5 Compliance: Passes surge tests up to 2kV, providing reliability in harsh power conditions.
