CQ220-16D is a type of thryistor that belongs to the TRIAC family (Triode for Alternating Current). It is used in a variety of applications ranging from industrial automation, HVAC, household appliances and lighting control. This article is aimed to provide an overview of its application field and working principle and why CQ220-16D is suited for a particular application.The CQ220-16D is a 4-pin, 400V, 16A TRIAC, which means it can handle up to 16A of Alternating Current. It is suitable for use in a variety of applications, including lighting control, home appliances, HVAC and industrial automation. It is also suitable for use in applications requiring high-voltage, high-current control.In terms of application field, CQ220-16D can be used for ON/OFF controls for motors, lights, heating systems and other equipment. It is also ideal for trigger and control in switching power supplies, as it provides improved surge and overvoltage protection compared to standard TRIACs. In the industrial sector, CQ220-16D can be used for temperature control, speed control, and protection for motors, drivers and relays. The working principle of the CQ220-16D is quite simple. When a voltage is applied between its gate terminal and the MT1 terminal, a trigger current will flow through the TRIAC\'s gate-triggered junction, triggering a self-sustaining avalanche breakdown process that activates the TRIAC. This process is known as the triggering biasing. The CQ220-16D is also unique in that it can be triggered at both the positive and the negative half-cycle of the AC wave, making it suitable for applications requiring symmetric triggering.The CQ220-16D is well suited for applications that require symmetric triggering and AC control, as well as reliable operation. It can be used in a wide range of applications due to its high voltage, high current ratings and triggering capabilities. The device is also designed in a way that makes it easy to use and very reliable in operation.In conclusion, the CQ220-16D is a versatile, powerful and efficient TRIAC suitable for use in a variety of applications. The device\'s ability to be triggered at both the positive and the negative half-cycle of the AC wave make it ideal for symmetric triggering applications. It also has high voltage, high current ratings and reliable operation. The CQ220-16D is therefore well-suited for applications that require symmetric triggering and AC control, as well as reliable operation.
