Thyristors - TRIACs

L2004V5TP Application Field and Working Principle

TRIACs, or Triode Alternating Currents, are a type of thyristor that are used in many applications because of their efficient switching and controlling of AC circuits. TRIACs offer essential features such as bidirectional blocking, soft-starting, and zero-crossing operation, making them ideal for a variety of AC applications. The L2004V5TP is a particular example of a triac that has multiple applications, from light dimming and fan speed regulation to phase control in motor drives and other high power applications.

The L2004V5TP

The L2004V5TP is a 4A, 800VMOSFET-controlled triac that offers superior gate control capabilities. It is available in a standard D2Pak power module as well as different pin configurations, making it suitable for a wide variety of alternate package types. As a through-hole device, a majority of its features are better suited for high power requirement applications, such as motor drives and UPS systems. The majority of these features include superior blocking voltage breakdown capabilities up to 800V, blocking accuracy up to 0.2% of the unit\'s rating, a high peak blocking current rating up to 4A, and a low on-state voltage drop of 0.7V in hard switching applications.

Working Principle

TRIACs are bistable switches that are designed to control high power levels in both directions. TRIACs, unlike transistor switches, can be triggered into ‘alternate half cycles’, or into any part of the sine wave. When a TRIAC is set to a particular polarity, the gate current can be used to trigger the alternation of positive and negative currents. The working principle of the L2004V5TP is similar to any triac design. The TRIAC is set in a ‘full-off’ or ‘non-conducting’ state until the voltage reaches a certain threshold. This threshold level can be adjusted to control the width of the current pulse being generated and is often used to control the speed and intensity of an AC powered appliance. Once the voltage threshold is exceeded, the TRIAC will conduct and allowed the current to flow in both directions.

Application Field

The L2004V5TP is designed to be used in a variety of AC applications, such as AC motors and drives, as well as UPS, light dimmers and other household appliances. The L2004V5TP is designed to offer superior gate control features that enable accurate, high-frequency switching of the AC circuit. The superior gate control features of the L2004V5TP enable it to be used in a variety of AC circuits and applications, including:

• Light dimming and fan speed regulation
