BTA24-600BW

BTA24-600BW Description

The BTA24-600BW from STMicroelectronics is a high-performance Snubberless™ TRIAC designed for robust AC switching applications. With a 600V off-state voltage and 25A RMS on-state current, it delivers reliable power control in demanding environments. This single-configuration TRIAC features a low gate trigger current (Igt) of 50mA max and a gate trigger voltage (Vgt) of 1.3V max, ensuring easy drive compatibility with microcontrollers or logic circuits. Its 75mA holding current (Ih) and high surge current capability (250A/260A non-repetitive at 50/60Hz) make it suitable for handling inrush currents in inductive loads. Packaged in a TO-220 through-hole format, it is ideal for industrial and consumer applications requiring high-voltage switching.
