TVS - Diodes: SMAJ16C Application Field and Working Principle

A TVS, or transient voltage suppressor diode, is a device that quickly responds to a high-voltage impulse on a circuit line to suppress excessive voltage. The SMAJ16C is one of the many TVS diode models in production and is manufactured by UnitedChemlabs. It is widely used for the protection of static electricity on electronic circuits.

The SMAJ16C is a surface mount diode designed for general purpose use. It has multiple powering options, ranging from 6.5 to 500 volts peak with a maximum surge of 16 amperes. The device dissipates an average power of 500 watts when operating at the peak voltage. The diode does not conduct reverse currents, ensuring that its protection does not interfere with the normal operation of the circuit.

The working principle of the SMAJ16C can be broken down into three stages: voltage sensing, current limiting, and voltage and current protection. During the voltage sensing phase, the device constantly monitors the voltage present on the circuit. If the voltage level exceeds a preset value, the SMAJ16C will switch on. During the current limiting stage, the device reduces the current flowing through the circuit to a safe level. Lastly, the device protects the circuit from high voltages and currents by releasing a discharge spark that shields the connected components.

In addition to its protective capabilities, the SMAJ16C is also employed in applications that require voltage monitoring. This includes mobile phones, radios, and other portable devices. The device’s ability to monitor the voltage of the circuit is also beneficial for real-time applications, such as medical equipment or factory automation systems. The SMAJ16C is also used in solar energy systems to protect the voltage converters and solar cells.

The SMAJ16C is an effective and reliable component, designed to protect circuits against transient voltages and currents. It is designed for a wide range of applications and can be conveniently mounted on a circuit board. The three-stage working principle allows the device to actively monitor and protect the circuit, and ensures that the connected components remain unaffected by high voltage and current.
