SMAJ11CAHE3/5A Application Field and Working Principle

Transient Voltage Suppressors (TVS) are electronic components used to protect other components from over-voltage transients. The SMAJ11CAHE3/5A is a unidirectional TVS diode used to absorb voltage spikes and prevent damage to other components in telecommunications, data communications, and other electronic products. In this article, the application field of the SMAJ11CAHE3/5A, as well as its working principle, will be discussed.

Application Field of SMAJ11CAHE3/5A

The SMAJ11CAHE3/5A is a unidirectional TVS diode with a peak pulse power dissipation of 11000 Watts (W) and a standoff voltage of 5 volts (V). It is designed to be used with high-speed data lines, such as those used in telecommunications and data communications.

The SMAJ11CAHE3/5A provides efficient suppression of over-voltage transients, such as electrostatic discharge (ESD). It is capable of handling up to 8kV of ESD and is rated up to 200 watts (W) for 8/20 microseconds (μs) surge events. This diode is also suitable for use in applications that require improved signal integrity, such as radio frequency interference (RFI) and electromagnetic interference (EMI) immunity.

The SMAJ11CAHE3/5A is designed for easy mounting and installation. It has an operating temperature range of -55 degrees Celsius (°C) to 125°C, allowing for use in both high and low temperatures. It also features an open tongue construction design to provide excellent mechanical stability and self-healing properties, which reduces the risk of damage in high-temperature environments.

Working Principle of SMAJ11CAHE3/5A

TThe SMAJ11CAHE3/5A is a unidirectional TVS diode, meaning it only allows electrical current to flow in one direction. When an over-voltage transient event occurs, the diode will dissipate the excess electrical energy by redirecting the current away from the protected components.

The SMAJ11CAHE3/5A is designed with a reverse breakdown voltage of 5 volts (V). This is the voltage level at which the diode will activate and begin to dissipate the transient current. When the voltage level rises above 5V, the diode will become conductive and the excess energy will be diverted to ground, protecting the components from damage.

The SMAJ11CAHE3/5A is also equipped with a clamping voltage equal to the reverse breakdown voltage. This is the voltage at which the diode will limit the flow of current to the protected components. By limiting the current to a safe level, the diode will ensure that the protected components remain undamaged.

In addition, the SMAJ11CAHE3/5A is designed with a low capacitance of typically 3.5pF to reduce signal distortion on high-speed data lines. Its small size and lightweight design also make it perfect for applications where space is limited.

Conclusion

The SMAJ11CAHE3/5A is a unidirectional TVS diode designed for use in telecommunications, data communications, and other electronic applications. It is designed to limit the current flow to the protected components by activating at a voltage of 5 volts (V) and limiting the current to a safe level. This diode is also equipped with a low capacitance of 3.5pF to reduce signal distortion, making it perfect for high-speed data lines.
