TVS - Diodes - SMDA24C-7/TR7 Application Field and Working Principle

Transient Voltage Suppression (TVS) diodes are a class of semiconductor device which provide voltage protection against electrical transients. They are a type of voltage regulator which limit the voltage that passes through them. TVS Diodes are made from silicon or polymer materials and are typically used in circuits that handle high-voltage or large currents.The SMDA24C-7/TR7 is a TVS diode specifically developed to protect vehicles from electrical surges caused by electrical systems such as electronic control units (ECUs), alternators, sensors, starters, and other engine components. It can protect vehicles from damaging voltage spikes of up to 24V.

FEATURES AND APPLICATIONS OF SMDA24C-7/TR7

The SMDA24C-7/TR7 is a low-capacitance, bidirectional diode specifically designed to protect vehicles from high-current electrical transients such as alternators, motors, and ECUs. This diode features a low clamping voltage, a voltage standoff of 24 volts, and a reverse breakdown voltage of 30 volts. Its operating voltage range is 3 to 50 volts with a maximum reverse current of 15mA. This diode also features a low capacitance of 10pF maximum and is ideal for fast switching applications.The SMDA24C-7/TR7 is commonly used in a wide range of vehicles, including vehicles used in police, fire, and military services, as well as recreational vehicles and electric vehicles. It is also applicable in any circuit where protection against high-current transients is required. It performs well in high-tolerance, low-power applications, as well as in high-power, heavy-duty applications.

WORKING PRINCIPLE OF SMDA24C-7/TR7

The SMDA24C-7/TR7 works by limiting over-voltage transients such as alternators, motors, ECUs, and a wide range of other electrical components. It does this by clamping the voltage at a certain level, known as the clamping voltage. This is the point at which the diode begins to conduct, limiting the excess voltage and protecting the circuit from damage.When the voltage across the diode rises above the clamping voltage, the diode begins to conduct current and its resistance decreases. The current flowing through the diode increases until the applied voltage reaches its breakdown voltage, at which point the diode can no longer conduct current and the voltage is clamped at the breakdown voltage.The SMDA24C-7/TR7 also has a low capacitance of 10pF, allowing it to operate quickly and accurately in fast switching applications. This makes it an ideal choice for use in vehicles, where it can protect the sensitive electrical components from costly voltage spikes and surges.

CONCLUSION

The SMDA24C-7/TR7 is an ideal choice for protection against over-voltage transients such as alternators, motors, ECUs, and a wide range of other electrical components. It is also a good choice for applications where low-capacitance, fast-switching performance is required, such as vehicles, military vehicles, recreational vehicles, and electric vehicles.By clamping the voltage at a certain level, the SMDA24C-7/TR7 is able to protect the sensitive components from costly voltage spikes and surges. It is an efficient, reliable solution for any circuit where protection against high-current transients is required.
