Thyristors - TRIACs

A TRIAC (or Thyristor TRIode for Alternating Current) is an electronic component that uses three layers of semiconductor material in a three-layer transistor structure. It is a bistable, current-controlled switch.A TRIAC is capable of controlling larger voltages and currents than an SCR (silicon controlled rectifier).

Z0103NN0,135 Application Field and Working Principle

The Z0103NN0, 135 is a silicon, 4 quadrant TRIAC device with a rated current of 135A and a peak on-state current of 200A. It is ideally suited for switching AC loads in high power applications such as air conditioning, welding, and ovens.

The working principle of a TRIAC is similar to that of a conventional diode. It acts as a switch that can be triggered on or off by the application of an external electric field. When the external electric field is applied, the gate current switches on and the TRIAC begins to conduct current. When the gate current is reduced, the TRIAC turns off. This principle of operation is known as gating.

The Z0103NN0, 135 is a four-quadrant TRIAC, which means that it can be triggered in two directions: first when the gate voltage is increasing, and then when the gate voltage is decreasing. This makes the device ideal for AC applications where the voltage direction can vary continuously.

The Z0103NN0, 135 features a high current rating and low gate current requirements, making it ideal for high power applications. It can also be used in low power applications such as motor speed control and sound systems.

The Z0103NN0, 135 has a wide operating temperature range of -40°C to +100°C and a maximum gate current of 0.7mA. This device also has an excellent dielectric strength of 3.7kV and surge resistance of 10kV.

In summary, the Z0103NN0, 135 is a high power four-quadrant TRIAC that is ideal for switching AC loads in high power applications. It has a high current rating and low gate current requirements, a wide operating temperature range, and excellent dielectric and surge resistances.
