Thyristors are complex semiconductor components that are the foundation of many types of consumer electronics, industrial electronics and communication systems. In particular, TRIACs (or Triode Alternating Current Switch) is a type of thyristors often used in AC circuits. The L2X8E5 is a specific TRIAC model released by Toshiba. In this article, we will explore its applications and working principles in detail.

L2X8E5 Application Field

The L2X8E5 is a 2-pin industrial grade surface mount TRIAC, which can handle up to 8.5A in AC current. Its temperature range is between -40°C and 125°C, and its maximum junction temperature is 175°C. Its typical voltage is 24V, but it can support up to 500V alternating current (AC). Due to its compact form, this type of TRIAC is suitable for various kinds of applications, such as heating systems, lighting controls, thermal controls, and industrial automation.

This model is also used in a wide range of applications, ranging from domestic products to commercial products and industrial equipment. Specifically, it is applicable for power supply, motor control, AC operated equipment and light switch applications. It is also used for temperature monitoring in industrial processes, motor and transformer protection, and speed control of AC motors. Furthermore, it is also used to control the heating elements in ovens and oven fans.

L2X8E5 Working Principle

The working principle behind the L2X8E5 is the same as any other TRIAC. It is composed of several layers of semiconductor material, which act as an insulation gate. When the gate is energized, the TRIAC is turned on, i.e. it switches to an “on” state. Then, the AC current will flow between the anode and cathode and the TRIAC will be in an “on” state as long as the gate current remains above the gate threshold voltage.

The L2X8E5 is designed so that the current flow can be controlled by adjusting the gate threshold voltage. This means that when the gate voltage is increased, the current flow decreases and vice versa. When the gate voltage reaches the turn-off voltage, the TRIAC will turn off and the current flow stops. This feature enables the L2X8E5 to be used for controlling the flow of AC current in various applications, such as lighting control, speed control of AC motors, and thermal control.

In addition, the TRIAC is also designed to have a high surge current capability, which enables the device to handle high current flow. As the voltage applied to the gate increases, the surge current that is allowed to flow through the TRIAC also increases. This makes the device suitable for a wide range of applications, including motor control and power supply.

Conclusion

The L2X8E5 is a 2-pin industrial grade surface mount TRIAC manufactured by Toshiba. It is mainly used in AC circuits, such as lighting controls, thermal controls, power supplies, motor control, and temperature monitoring in industrial processes. Its working principle is based on controlling the flow of AC current by adjusting the gate threshold voltage. It is also designed to have a high surge current capability, which makes it suitable for a wide range of applications.
