TVS - Diodes are components that can be used to protect electronic circuits against voltage surges, and BZW04-48BHE3/73 is one such compoent. It utilizes the principle of avalanche breakdown effect to protect the peripheral circuit against electrostatic discharge and other voltage transients.

Upon application of a high voltage, current through the component increases drastically and the associated power dissipation can lead to a breakdown, causing a conduction path for the current to flow through. This depletion region surrounding the component blocks further voltage rise and limits the magnitude of the transient to almost constant value. In turn, this protects the circuit from being damaged due to high-voltage transients.

This component has mainly two functionands: clamping and biasing. The clamping functionand is responsible for diverting the transient due to shock voltages. During the transient phase, the device acts as an electrical barrier and limits the voltage rise of the protected circuit, thus preventing it from damage. The biasing functionand is responsible for maintaining the static and dynamic operating characteristics of this component. It acts as an active stabilizing element that holds the voltage level stable during normal operation and the dynamic operation, thereby reducing the possibility of component malfunction.

This component is usually made from silicon or gallium arsenide semiconductor material and uses the breakdown characteristic of the material to absorb the electrical transients. The device is capable of providing protection up to a voltage rating of 48V with a 35A peak pulse current capability. It can also be used for a wide range of applications such as AVL/I7 protectors, motor control, automotive engine control systems, capacitors and voltage regulators.

BZW04-48BHE3/73 can be used in different applications, such as low-power audio circuits and high-speed switching circuits. In low-power applications the device prevents malfunctioning due to electrostatic discharge or under high-speed switching operations it can limit the noise and voltage transients that may affect other components. Additionally, it helps reduce EMI and RFI interference across the entire system.

In conclusion, the BZW04-48BHE3/73 is a robust component that can be used for protecting electronic components from voltage transients. It is capable of protecting voltage levels up to 48V with a 35A peak pulse current capability, which can be used for a wide range of applications. The device utilizes the principle of avalanche breakdown effect to protect the circuit against electrostatic discharge and other voltage transients, it also helps reduce EMI and RFI interference across the entire system.
