BTA12-800B Triac 800V 12A TO-220AB
The BTA12-800B Triac is a robust, insulated semiconductor device from STMicroelectronics, engineered for efficient AC power control in a variety of electronic systems. This Snubberless Triac features a three-quadrant operation with high commutation capability, making it particularly effective for handling inductive loads without the need for external snubber circuits. It supports both ON/OFF switching and phase control modes, allowing precise regulation of power delivery to loads such as heaters, motors, and lamps.
Features:
• High RMS on-state current capacity of 12 A for robust load switching.
• Repetitive peak off-state voltage rating up to 800 V for mains AC compatibility.
• Snubberless™ design with low thermal resistance and insulated ceramic tab.
• UL1557 certified insulated tab construction compliant with safety standards.
