Thyristors - TRIACs
A TRIAC (Triode for AC) is a three terminal unilateral semiconductor switch, which is able to carry current in both directions with help of its four layers of alternating P and N material as shown in fig. 1. These semiconductor devices belong to the thyristor family.
Fig. 1 –Triac Structure
TRIACs are usually used in AC circuits to switch, control and regulate the power. They are mainly used as a power switch in applications such as motor control, light dimming, lighting control, etc. Some other applications of TRIACs are starting AC motors, controlling household appliances, wire wound resistor and spark gap protective devices.
The T405-700B-TR is a TRIAC module manufactured by Fujikura Automotive Industries. This device is primarily used for motor control in automotive applications. It has a maximum current rating of 700A and a breakdown voltage of 400V. It is also equipped with an integrated snubber circuit for increased protection and improved safety in operation. The basic principle of operation is to use the PN junction of the TRIAC to switch the AC current on and off, as illustrated in fig. 2.
Fig. 2 - T405-700B-TR Working Principle
When a voltage is applied to the gate terminal of the device, the PN junction of the TRIAC is forward biased, allowing current to flow through it. The device is then said to be in the “on” state. When the gate voltage is removed, the current flow is interrupted, returning the device to the “off” state.
In summary, the T405-700B-TR is a TRIAC module primarily used for motor control in automotive applications. It has a maximum current rating of 700A and a breakdown voltage of 400V. It is also equipped with an integrated snubber circuit for added protection. The basic principle of operation is to use the PN junction of the TRIAC to switch the AC current on and off.
