Q2004D3TP

Thyristors - TRIACs are a type of semiconductor component used for power control in various applications. The Q2004D3TP is a four-terminal, three-phase triac from ROHM Semiconductor with a maximum continuous blocking current of 4A. This triac is ideal for home appliances, office equipment and industrial applications such as motor control, light dimming or surge suppression.

The Q2004D3TP is constructed of two opposed thyristors connected in an inverse parallel configuration. By applying a voltage across two of the three gate terminals, the gate current flows through the base regions of both thyristors in an opposite direction. This causes one thyristor to conduct while the other thyristor is blocked. When the gate voltage is reversed, the direction of the current is also reversed and the thyristor which was conducting before is now blocked while the other thyristor conducts.

The main difference between a triac and two thyristors is that in a triac, the current can flow in both directions or bidirectional current capability. This makes the Q2004D3TP ideal for controlling electrical power in AC circuits as it can switch from 0 (off) to maximum power in either direction.

The Q2004D3TP has a maximum Gate Trigger Voltage of 8 Volts and a Gate Trigger Current of 3 mA. This allows for easy turn-on and off control of the triac for various switched applications. It also has a very low gate power dissipation of only 750mW.

The Q2004D3TP has a balanced current carrying capability and low on-state voltage drop which make it suitable for supplying power to high power devices such as motors. This makes the triac a popular choice for motor control applications. The triac\'s bidirectional conductivity also allows it to offer protection against surge currents, making it ideal for use in LED lighting applications.

Ultimately, the Q2004D3TP can be used in a variety of applications due to its bidirectional capability, high current carrying capacity, low on-state voltage drop and ability to control power in AC circuits. This makes it an ideal choice for home appliances, office equipment, motor control, light dimming and surge suppression applications.
