Overview

MASMCGLCE22AE3 is a transient voltage suppressor, or TVS-Diode. It is a type of semiconductor protection device made for protecting sensitive electronics from potentially damaging voltage transients. These components are employed for a wide array of electronic devices and serve different applications in industry and consumer based products.

Applications

One specific application lies in protecting low voltage or high voltage circuits, such as TTL logic, high voltage power supply, and wireless communication devices. The range of electrical parameters that the MASMCGLCE22AE3 series can protect against includes both over-voltage and under-voltage events. To further explain, the device can protect computers, routers, and other electronic products against transient voltage spikes caused by lighting strikes, but also vulnerable areas from ground loop injection common in AC power lines. Not only are these devices effective in protection, but also very small within surface mount packages, making them the choice application for lots of industries. The MASMCGLCE22AE3 series has a wide range of over-voltage protection that makes them an effective choice for applications such as automotive, industrial, consumer, telecom, and military.

Uses

The MASMCGLCE22AE3 series is specifically designed as a surface mount device for an even smaller footprint and smoother assembly flow. This is useful for safeguarding electronic components from voltages in excess of their ratings and, in some cases, from voltages that may be below their normal operating range. They are often used during normal operation of electronic devices to maintain the proper amount of voltage within the circuit, preventing power fluctuations or power interruptions. Additionally, they can also be used for protection during the start-up of an electronic device, either by limiting the amount of current drawn in or protecting from high voltage during power-on.

Benefits

The number one benefit of the MASMCGLCE22AE3 series is its exceptional robustness. It can handle high voltage transients, withstanding up to 5,000 volts for peak pulse current. Its surge capability makes it perfect for protecting circuits from electrical surges and contributes to its ability to successfully reduce the impact of intense over-voltage transients. The MASMCGLCE22AE3 series also offers better thermal impedance against heat than other models on the market, resulting in the product having a much longer life span. It also has a higher temperature coefficient that allows it to react more effectively to thermal stress than its counterparts.In terms of cost, the MASMCGLCE22AE3 series is very competitive with other protection devices. Moreover, its small size and its fast response time during operation saves manufacturers money in production costs, as well as reduces the overall space taken up in the product. It is also cost effective since it is highly durable compared to other TVS-Diodes on the market.

Working Principle

The working principle of the MASMCGLCE22AE3 TVS-Diode is simple yet effective. During normal operation, the diode conducts electricity, allowing power to flow through the circuit board. When a voltage transient occurs, such as an over or under voltage transient, the diode responds by clamping the potential voltage, preventing it from damaging connected components. This is achieved by the diode capacitance encasing the device and blocking the signal. The voltage clamp functions similarly to other protection devices, as without a protection device, connected components would be exposed to sustained high voltage, resulting in a short circuit. The TVS-Diode suppressor, such as the MASMCGLCE22AE3 series, prevents the excessive high voltages that can cause damage.

Conclusion

The MASMCGLCE22AE3 series of transient voltage suppressors provides fast, robust and cost-effective protection against over and undervoltage transients, and other potential voltage spikes. Its small size and fast response time make it an optimum choice for many industries, while its exceptional robustness and surge capability make it an ideal choice for protecting against voltage transients. With a wide range of over-voltage protection, this series is the perfect choice for any application requiring over-voltage protection.
