The SMCG7.5A-HRA is a TVS Diode designed to protect vulnerable electronic equipment from electrical transients induced by external lightning on power and signal lines. It assists in satisfying IEC 61000 regulations by providing a low clamping voltage in combination with a fast response time. Suitable applications include AC/DC power supplies and power motors as well as I/O interfaces.

A TVS diode is a type of diode specifically designed to protect vulnerable electronic equipment from electrical transients induced by outside sources. They are usually constructed from a wide array of junctions that are arranged as either two or three terminals. The voltage-clamping action of these diodes provides a fast response time and therefore a very wide peak-pulse current rate. An important feature of TVS diodes is that they operate in regions where the triggering process is activated due to a specific overvoltage threshold.

The SMCG7.5A-HRA is a bidirectional transient voltage suppressor that features very low leakage current and fast response time. It also features a low clamping ratio for a voltage range of 7.5 mV to 125 mV. This makes it suitable for providing ESD protection for AC/DC power supplies and data lines. With the combination of its low clamping voltage and fast response time, it is ideal for applications requiring fast protection from ESD, EFT, or lightning transients.

The working principle of the SMCG7.5A-HRA is based on the metal-oxide-semiconductor (MOS) structure. This structure consists of a p-type and an n-type layer, with a voltage-controlled gate electrode sandwiched between them. When the voltage on the gate electrode is raised above the threshold level, it increases the conduction resistance of the p-layer, and allows the current to flow more freely from the p- to the n-type layer. When enough voltage is applied to the device, the peak current rate is achieved, allowing it to act as a fast and effective transient suppressor.

The SMCG7.5A-HRA provides an extremely fast response time when compared to most other TVS diodes on the market. This makes it suitable for use in applications where the speed of response is critical in order to provide a reliable level of protection. This fast response time is due to its increased area of effective junction size, allowing it to absorb more energy and reduce ESD and transient voltages quickly. This ensures that sensitive electronic equipment is protected in even the most extreme electrical environments.

The SMCG7.5A-HRA is suitable for a wide variety of industrial, commercial, and consumer electronics applications where fast and reliable transient protection from ESD, EFT, and lightning is required. It is ideal for use in AC/DC power supplies, I/O interfaces, power motors, and other sensitive electrical equipment. With its low leakage current and fast response time, the SMCG7.5A-HRA is an economical and reliable solution for transient protection.
