The STMicroelectronics BTB24-600BRG with Triac is a thermal circuit breaker with a 600V rating, 25A current capacity, 50mA breaking capacity, and a Through-Hole (THT) tube design (package type TO220AB). It is designed for over-current and over-temperature protection of power electronic applications, such as motors and AC/DC converters. It also has a fast response time and a low thermal resistance, making it ideal for applications where space and weight are a factor. The BTB24-600BRG has an operating temperature range of -40°C to +125°C, a better than -20dB noise rejection filter rating, and a typical on-state resistance of 4.5mohm. These features make the BTB24-600BRG suitable for a wide range of AC and DC circuit applications.
