Sensitive-gate thyristors with 8 A current rating for dimmer switch control
The TS820 silicon-controlled rectifier (SCR) thyristors from STMicroelectronics are ideal for use in dimming light switches for low-power LED or fluorescent lamps, providing flicker-free output and high power efficiency.
The TS820 series of SCR thyristors from STMicroelectronics provide an efficient way to control the current through lighting dimmer switches thanks to the highly sensitive gate. The low gate current means that the SCR thyristors can be controlled by a very small power supply.
The 8 A-rated TS820 SCR series is suitable for all modes of control found in dimmer switches, and in other applications such as over-voltage crowbar protection, motor control circuits, inrush current limiting circuits, capacitive discharge ignition, and voltage regulation circuits.
The SCR thyristors are available in through-hole and surface-mount packages.
