The BZW04-15BHE3/73 is a kind of TVS - Diode, which utilizes various features in order to protect against high-voltage transients. Unidirectional and bidirectional configurations are available that are suitable for applications requiring protection against both positive and negative transient voltages. Plus, BZW04-15BHE3/73is typically used for automotive, commercial, industrial, and military applications, providing protection against surges, spikes, ESD, and EFT.

The protection mechanism of BZW04-15BHE3/73 operates by being triggered when the transient voltage of the line exceeds a certain reference level. The device then switches on and clamps the voltage to a safely acceptable level, ensuring that the circuit or component protected against electrostatic discharge, over voltage, inductive load switching, or over-current situations is not damaged.

When the transient voltage level falls below the reference level, the diodes turn off and reset, and the process starts again. As they reset, they draw minimal current, which is important for environmental sustainability, as this current would otherwise be lost as heat, further not influencing any of the other systems. This makes them an excellent solution to implement in any system, regardless of the application.

In terms of working principles, BZW04-15BHE3/73 is generally based on the principle of Zener-breakdown protection, which is that the PN junction starts to conduct at a certain voltage drop. As the resistor in the junction is reduced due to the application of high current or high voltage, the voltage drop across the diode triggers the breakdown of the junction. The device therefore starts conducting current through it until the supra-specified voltage limit is exceeded. As the current passes through the diode, the breakdown voltage is maintained and the diode continues to protect against this form of overvoltage.

As mentioned before, BZW04-15BHE3/73 is typically used in a variety of applications, such as automotive, commercial, industrial, and military. For example, it can be used in automotive applications to protect circuits and components such as ECUs, GDI injectors, and high-pressure fuel pumps from transient overvoltages that may occur due to load dump, injection, or electromagnetic interference. In commercial, industrial, and military applications, BZW04-15BHE3/73 can be used to prevent damage to equipment or data loss caused by abnormal or hazardous voltage levels.

Overall, the BZW04-15BHE3/73 is a type of TVS (transient voltage suppressor) diode, which is designed to protect various circuits and components from voltage transients caused by electrical disturbances such as load-dumps, overvoltage, ESD, and EMI induced transients. The device utilizes a Zener-breakdown protection principle wherein the PN junction starts to conduct at a certain voltage drop, thus clamping the voltage down to an acceptable level. It can be used for a variety of applications, such as automotive, commercial, industrial, and military, for which it can prevent damage, data loss, and system malfunctions.
