A TVS Diode is an electronic device that can protect a circuit from large voltage spikes, such as those generated by lightning. They are commonly used in industrial, automotive, and consumer electronics applications where voltage surges could cause damage. The SLVU2.8-4BTG-S is a TBTS diode designed for automotive applications.

The SLVU2.8-4BTG-S is designed to protect systems from transient voltage events up to 2.8V. It can handle up to 3A surge current at 2.8V and 4A surge current at 1.75V. The device is designed with low capacitance, allowing it to have a fast response time to transient voltage spikes. The SLVU2.8-4BTG-S has a low clamping voltage, which is important for protecting sensitive electronics, and is RoHS-compliant for environmental friendliness.

This device is specifically designed for automotive applications, where it can be used to protect against high voltage surges from the alternator, insulate sensing circuitry from the electrical noise of the engine, and protect against other electrical events. The SLVU2.8-4BTG-S can handle high reverse voltage spikes up to 4V, with a maximum peak current of 5A for up to 6ms. The device also has surge endurance up to 1A over 10,000 pulses.

The SLVU2.8-4BTG-S also has a working temperature range of -55 to 125 degrees Celsius. This allows it to be used in extreme environments without any problems. The device also has a low stand-off voltage, which is important for when the system voltage is low.

The working principle of the SLVU2.8-4BTG-S is simple. When the transient voltage exceeds the device’s rated clamping voltage, an avalanche breakdown occurs. This causes a current to flow from the anode to the cathode, which dissipates the energy. The device then restarts once the transient voltage has been dissipated.

In summary, the SLVU2.8-4BTG-S is a TBTS diode designed for automotive applications that can protect systems from transient voltage events up to 2.8V. The device has a low capacitance and a low clamping voltage for protecting sensitive electronics, and is RoHS-compliant for environmental friendliness. It has surge endurance up to 1A over 10,000 pulses, a working temperature range of -55 to 125 degrees Celsius, and it works on the principle of avalanche breakdown.
