Z0103MA 2AL2 Discrete Semiconductor Products

Thyristors - TRIACs

The Z0103MA 2AL2 is a TRIAC (or thyristor switch) device from STMicroelectronics. It is a bistable semiconductor device with three terminals, mainly composed of a main terminal (MT) for direct current or alternating current control and two terminals for load power supply. Generally speaking, TRIACs are used for switching AC power.

The Z0103MA 2AL2 device is equipped with an MT2 gate for triggering action. The voltage between the gate and MT2 is used to control the main current, allowing the power to flow or the current to be blocked. When a positive pulse is applied to the gate, the device will switch into on-state and the voltage drop across the device will be small. When the pulse ends, the current flowing through the device will be forcibly interrupted, and the device will automatically adjust itself to the off-state.

The Z0103MA 2AL2 is most suitable for AC switching applications, and it is often used in power electronics such as motors, lamps and solenoids. It can be used to control the speed of a motor, to dim the light intensity of a lamps, or to turn a solenoid on or off. By connecting the Z0103MA 2AL2 with a control circuit, it can be used to switch the power on and off in a specific sequence. It can also be used for phase control applications, where it can be used to adjust the load current without affecting the line voltage.

The Z0103MA 2AL2 works on low power and can be used in a wide voltage range. It requires minimal control voltage to switch its operation. It is also insensitive to temperature changes, making it a reliable and stable device for various applications. Its low dissipation and low on-state voltage drop make it an ideal choice for applications where power efficiency is of great importance.

In conclusion, the Z0103MA 2AL2 is an ideal device for AC switching applications. With its versatile features, it can be used in switching and phase control applications, making it a reliable and power efficient choice in power electronics.
