ACS108-6SA

ACS108-6SA Description

The ACS108-6SA from STMicroelectronics is a sensitive gate TRIAC designed for efficient AC load control in low-power applications. It features a 600V off-state voltage and a 450 mA RMS on-state current, making it suitable for switching and phase control in compact electronic systems. Packaged in a TO-92 through-hole format, this TRIAC is part of the ACS™/A.S.D® series, known for reliability and performance in consumer and industrial electronics. With a gate trigger current (Igt) as low as 10 mA and a gate trigger voltage (Vgt) of 1V max, it ensures easy drive compatibility with logic-level circuits.

ACS108-6SA Features

• Low Trigger Requirements: Operates with minimal gate current (10 mA max) and voltage (1V max), reducing driver complexity.
• High Surge Current Handling: Supports non-repetitive surge currents of 7.3A (50Hz) and 7.6A (60Hz), ensuring robustness against transient loads.
• Compact & Reliable: TO-92 package with MSL 1 (unlimited) moisture sensitivity, ideal for cost-sensitive designs.
• Compliance & Durability: ROHS3 and REACH compliant, with 600V blocking voltage for high-voltage isolation.
• Low Holding Current: 25 mA max holding current (Ih) enhances energy efficiency in standby modes.
