BT137-600E is a product manufactured by NXP Semiconductors. It is a three-terminal, phase control thyristor designed for medium power switching and phase control applications. It offers medium power operating capabilities with a blocking voltage of 600V, 10A DC current and 4A AC current. It also features a typical low on-state voltage drop of 1.3V at an operating current of 2A. Other features include a very short turn-off delay time and its ability to withstand high junction temperatures. With its very low thermal resistance and high surge capabilities, BT137-600E is particularly suitable for use in ac motor control, lamp dimming, heat control and light dimming applications.
