20W 5% Wire Wound Resistor

Silicon Controlled Rectifier (SCR) are a great way to control the power of high voltage applications. This is a 600V 1.5A SCR transistor.

Power Transistors are transistors which can handle a lot more power in compared to BJTs. Similar to BJTs, the current flow between the collector and the emitter of is controlled by the current flow through the base.

Insulated-Gate Bipolar Transistor is a high efficiency and fast switching transistor. Since IGBT is a three terminal power semiconductor, it can be used as an electronic switch.
