BZW04-7V8-E3/54

TVS - Diodes are an important surface-mount component used for protecting sensitive circuits against electrostatic discharge (ESD) and lightning-induced surges. The BZW04-7V8-E3/54 is an example of a TVS diode. It is a hermetically sealed glass body transient voltage suppressor (TVS) diode that has low capacitance, making it suitable for protection in high-speed circuits.

The main application field of the BZW04-7V8-E3/54 is in field-programmable gate arrays (FPGAs) and semiconductor circuits, where it can be used for protecting against electrostatic discharge (ESD) and lightning surges. It is designed to protect against transients up to 8kV, and has an operating temperature of -55 °C to 125 °C.

The BZW04-7V8-E3/54 works on the principle of a diode, in that when the reverse voltage across the diode exceeds a certain threshold (called the breakdown voltage), the diode starts to conduct. This is called avalanche breakdown, and it occurs when the electric field in the diode surpasses the breakdown field strength of the diode material. When this happens, the diode will conduct current even in the reverse direction, thus providing protection from transients.

The BZW04-7V8-E3/54 is capable of dissipating up to 180W of power in an 8/20μs pulse, and can maintain a maximum leakage current of 5μA. This ensures that the diode can withstand high transient voltages without being damaged. The device is also designed to have low capacitance, which makes it suitable for high-speed circuit protection.

In summary, the BZW04-7V8-E3/54 is a hermetically sealed glass body transient voltage suppressor diode. It is mainly used for protection of field-programmable gate array (FPGA) and semiconductor circuits against ESD and lightning surges. It functions on the principle of avalanche breakdown, and is capable of dissipating up to 180W of power in an 8/20μs pulse while maintaining a maximum leakage current of 5μA. The device also has a low capacitance, which makes it suitable for high-speed circuit protection.
