Power Control Solution: The Silicon Controlled Rectifier (SCR)
Modern life requires homes that are full of appliances which you could turn on and off at the push of a button. Electric dishwashers, stove tops, ovens, washing machines, clothes dryers, refrigerators, heaters and air conditioners are standard in many homes as they provide effortless convenience as well. Have you ever wondered what enables these appliances to obtain high-power electricity to function well? It’s SCR!
Sensitive Gate Silicon Controlled Rectifier (SCR), also known as a Thyristor, is a multilayer solid-state current-controlling device. It has four layers which normally consist of two P-N junctions and a gate. It is widely used to control high voltage and power for electronic devices.
When the SCR lacks an internal (gate to cathode) resistor, it can easily be triggered by the slightest positive gate signal or application of a small voltage. This is referred to as the Sensitive Gate SCR. These parts are being utilized for certain applications where high gate sensitivity is required.
Jiejie Microelectronics (JJM) is a professional manufacturer of semiconductor devices. Chip1 Exchange is one of the authorized distributors offering a series of Sensitive Gate SCR at a lower cost that we can cross for brands such as ST Microelectronics and NXP. Jiejie products have been widely and extensively applied in civic fields including, home appliance, leakage circuit breakers, industrial applications, lighting protection, and electrostatic protection fields.
