TVS diodes, which refers to Transient Voltage Suppressors, are a type of electrical protection device that provide specific levels of protection against transient electrostatic discharges (ESD) voltage spikes. The BZG04-91TR3 are designed for high-speed data line and sensitive electronic equipment protection. These devices employ a silicon avalanche diode under Zener breakdown voltage and have the capability of suppressing the transient voltage with low leakage current. In other words, the BZG04-91TR3 TVS provides a clamping protection against ESD and transient surges.

The BZG04-91TR3 is a diode with unlimited peak pulse power. It offers excellent protection against high energy, low and high frequency fast transients, ESD and electrical fast transients. The device provides over-voltage protection of data signals or power supply lines up to a voltage of 24 volts and operates at temperatures between -55 to 150 degrees Celsius. These devices have a high spike current and surge current handling capability, making them suitable for automotive and industrial applications. The BZG04-91TR3 devices have an ESD protection capability of up to 30KV and a peak pulse current of up to 8A.

The working principle of the BZG04-91TR3 TVS is that, when an excess voltage is applied to the diode, it will break down and opens the avalanche region (alternatively called the depletion layer), thus providing a low impedance path to the power rail or ground. This low impedance path prevents the further voltage increase across the diode. The device can absorb high energy spikes while providing a low voltage drop across the diode itself.

The BZG04-91TR3 TVS is designed for the protection of data signals, power supply lines, and sensitive electronic equipment. It is primarily used in automotive and industrial applications, such as automotive electronics, PCs, sensors, modules, and communication devices. These protection devices are an excellent solution for providing in-circuit protection or replacing fuses and breakers in less critical applications. They are also suitable for use in LED lighting and power supplies. The BZG04-91TR3 devices offer a low leakage current, low capacitance, and fast response times, making them a suitable choice for a wide range of applications.

In conclusion, the BZG04-91TR3 is a TVS diode that is designed for the protection of data signals, power supplies, and sensitive electronic equipment. It has a low leakage current and a high spike current capability that makes it suitable for a wide range of application. Furthermore, it provides excellent over-voltage protection and has an ESD protection capability of up to 30KV.
