TVS - Diodes are essential components in many forms of electrical circuitry and can help protect vulnerable equipment from unexpected power surges, voltage spiking, or static discharges. The SMAJ78E3/TR13 device is a unidirectional DC/DC TVS diode that is designed to be low-cost and can reduce save costs in many industrial applications. In this article, we will take a look at the application field of the SMAJ78E3/TR13 device and its working principle.

SMAJ78E3/TR13 Device Applications

The SMAJ78E3/TR13 device is a unidirectional TVS diode that is perfect for use in electromagnetic interference (EMI) and radio frequency interference (RFI) applications. It is commonly used in many industrial environments, such as in electrical motors, traffic systems, power supply systems, building automation, and HVAC systems. The device can help protect these systems from power surges, voltage spiking, and static discharges.

The device also has a wide operating temperature range, from -55 Celsius to 125 Celsius, which makes it a perfect choice for use in industrial applications. It is also able to withstand an operating voltage of 200V and a surge current rating of 400A, which makes it well suited for use in high-voltage and high-current applications.

SMAJ78E3/TR13 Device Working Principle

The working principle of the SMAJ78E3/TR13 device is quite simple. It is a unidirectional device, meaning that it is designed to only allow electric current to flow in one direction. When the device detects voltage spiking, static discharges, or other types of power surges, it quickly clamps down on the voltage level and acts as a bridge between the negative and positive terminal, allowing the current to bypass the vulnerable components of the system and thus protecting them from possible damage.

The device also features an ultra-low capacitance value, meaning that it is able to quickly clamp down on an incoming electrical surge. This can help prevent damage to vulnerable components and increase the overall reliability of the system.

Conclusion

The SMAJ78E3/TR13 is a unidirectional DC/DC TVS diode that is designed to reduce costs in many industrial applications. It is capable of withstanding an operating voltage of 200V and a surge current rating of 400A, and has an ultra-low capacitance rating, making it well suited for high-voltage and high-current applications. The device is perfect for use in EMI and RFI applications, and is able to protect the circuits in which it is installed from power surges, voltage spiking, and static discharges.
