About this product
The BT151-500R is a silicon controlled rectifier (SCR thyristor) rated for 500 V and 12 A in a TO-220 package. It conducts once a gate pulse triggers it and stays on until the current falls to zero. It is used to switch and control loads such as motors, heaters and lamps in power-control circuits.

Can it switch AC loads?
A single SCR conducts in one direction only, so it passes only one half of each AC cycle. For full-wave AC control, a triac is usually preferred, or two SCRs in anti-parallel. Check the datasheet for your application.
How do I trigger the gate?
Drive the gate from your controller through a series resistor, and connect the cathode to the reference or ground. Make sure the gate pulse meets the gate trigger current and voltage (IGT and VGT) in the datasheet.
