The BT149B is a silicon controlled rectifier (SCR) manufactured by Philips. It is designed for general-purpose switching and control applications requiring a single-element thyristor. The device features a nominal on-state RMS current rating of 0.8A and an off-state voltage rating of 200V. The trigger current is specified at 0.5mA, enabling reliable gate activation. The breakdown voltage is also rated at 200V. The BT149B is packaged in a standard TO-92 through-hole package with 3 terminals. It operates over a temperature range up to 125°C. This SCR is suitable for low-power phase control, motor speed control, and lighting dimmer circuits where a compact, cost-effective thyristor is required.
