SCRs and Triacs Datasheet
Topdiode Thyristors Used in Home Appliances ( Vacuum cleaner, juicer, rice cooker)
Home appliances cover a wide range, such as air conditioners, washing machines, electric kettles, and lighting systems. They require components that can effectively control power and ensure stable operation.
Thyristors come in various types like SCRs (Silicon Controlled Rectifiers). They are designed with a PNPN structure and specific doping concentrations. Thyristors can precisely control the power delivered to home appliances. For example, in an electric kettle, they can control the heating time and power to quickly and safely boil water. In a dimmer switch for lighting, thyristors adjust the light intensity by regulating the current.
Topdiode use advanced semiconductor manufacturing processes to produce high-quality thyristors. These have low forward voltage drops, reducing power loss and improving energy efficiency. They also have high voltage and current withstand capabilities, ensuring they can work stably in different home appliance circuits.

Topdiode SCRs and Triacs Applications
A thyristor is a type of semiconductor device that acts as a switch, controlling the flow of electrical current in a circuit. Thyristors are typically used for switching and controlling high voltage or current in applications where the power must be turned on or off. They are made of four layers of semiconductor material (P-N-P-N) and typically have three terminals: anode, cathode, and gate.
Silicon Carbide Schottky Barrier Diodes are semiconductor devices that consist of a metal contact on a layer of n-type Silicon Carbide (SiC) material. The metal contact forms a Schottky barrier with the SiC material, which allows the flow of current in only one direction. SiC Schottky barrier diodes offer several advantages over conventional diodes, including lower forward voltage drop, shorter reverse recovery time, higher breakdown voltage, and higher temperature operation
SCR (Silicon Controlled Rectifier):
-
- Structure: An SCR is a type of thyristor that has a single direction of current flow. It has four layers (P-N-P-N) and three terminals: anode, cathode, and gate.
- Control: It is controlled by a gate signal. Once triggered, it remains in the “on” state (conducting) until the current flowing through it drops below a certain threshold (called the “holding current”).
TRIAC (Triode for Alternating Current):
-
- Structure: A TRIAC is similar to an SCR but can conduct current in both directions, making it suitable for AC applications. It has a similar structure but with an additional set of layers.
- Control: Like an SCR, a TRIAC is controlled by a gate signal, but it can conduct during both halves of an AC cycle, allowing bidirectional control.
