Thyristors, also known as Silicon Controlled Rectifiers (SCRs), are a type of two-terminal semiconductor device that is used in many different application fields. One such type of SCR is the EC103MAP; understanding its application and working principle is therefore essential when considering using the device.

The EC103MAP is a current-limiting device, meaning it is used to prevent electrical circuits from being overloaded or to protect other electronic components from damage due to excessive currents. In this capacity, it is oftentimes employed in place of traditional fuses. The advantage of using an SCR rather than a traditional fuse is that, instead of having to replace the fuse each time it is used to limit an overload, the SCR can be reset after every triggering, meaning it can be reused.

The EC103MAP is a thyristor designed specifically for AC loads, meaning it is typically used in mobile equipment, residential and commercial wiring, industrial control systems and more. The device is also compact and typically installed in a plastic shell, meaning it can be incorporated into more restricted spaces.

The EC103MAP integrates several different silicon control components in order to control the current and protect the circuit. It features a parameter called Peak Off-State blocking voltage, which is applied in order to ensure the correct functioning of the circuit, as well as an integrated high voltage adjustable Zener diode, which provides protection against overvoltages in the circuit.

The EC103MAP is triggered when a surge of electricity passes through the device, but not always. If the current does not exceed the breakdown voltage, then the SCR does not get triggered. The SCR does not conduct until the gate receives a trigger current consisting of a positive voltage on its gate terminal, which forces the SCR to become “forward-biased” and a current starts to flow through the device.

The EC103MAP\'s “on-state” voltage is low, and when activated it offers a low resistance while maintaining a high current capability. It is this capability—low voltage and current protection—that has made SCRs an attractive alternative to traditional fuses, especially in the case of AC loads.

In summary, EC103MAP is a two-terminal semiconductor device that is used to protect electrical circuits from excessive currents, particularly AC loads. This is achieved through its peak off-state blocking voltage and integrated high voltage adjustable Zener diode. The device is triggered when a surge of electricity passes through the device, but not always. Once triggered, a low voltage and high current capability is offered.
