The BTA08-600BRG with TO-220 TRIACs is a Thyristor /Triac manufactured by JSMSEMI. It is a Silicon Controlled Rectifier (SCR) device that functions as either a switch or an analog current regulator. It has three pins: gate, main terminal 1 (MT1), and main terminal 2 (MT2). The gate is used for triggering the device, while MT1 and MT2 are used for current flow. This BTA08-600BRG has a maximum off-state voltage of 600 volts (VDRM or VD) and a maximum average on-state current of 8 amps (IT(RMS)). It is RoHS compliant and comes in a TO-220 package. The device is commonly used for load Motor Control, Home Appliance Control, Motor Soft Starting,Heating and Lighting Control, Industrial Automation, etc.
