TVS-Diodes are an important part of ESD protection. BZW04-154B-E3/73 is a professional TVS-diode which offers amazing ESD protection for electronics.

This diode has the capability to shunt away huge amount of energy while protecting electronic circuits from lightning transients without letting their components suffer from any reverse voltage damage. This TVS diode works on the principle of threshold between the breakdown voltage for avalanche effect and the breakover voltage for the zener effect. This threshold voltage is designed into the device.

The BZW04-154B-E3/73 is a unique ceramic-based TVS diode with excellent electrical and thermal characteristics. It can provide overvoltage protection to devices with higher accuracy. It is used as an inline series element in AC power lines to protect equipment from lightning surges.

It is primarily used in many applications such as automotive electronics, AC/DC power supplies, computers, consumer electronics, telecommunication equipment, office automation, industrial control systems, and low voltage power systems. It can effectively absorb extreme transient conditions, operating from 0 to 65V. Due to its low leakage current, reverse stand-off voltage, and low capacitance, this diode is a great choice for low voltage applications.

The working principle of BZW04-154B-E3/73 is simple and straightforward. It works on the principle of thermal runaway, where it allows current to flow in a controlled manner. The diode acts as a shunt when an excessive voltage is applied and starts to absorb energy as current passes through it. The absorbed energy increases the diode’s temperature, and consequently, its breakdown voltage rises. This process continues until the thermal runaway is complete, and eventually, the overvoltage condition is countered.

The working principle of this TVS-diode also ensures maximum power dissipated in the breakdown region. This is due to the characteristics of the diode itself, which are designed in such a way that it forces the return current to flow through a low-impedance path. This returns the maximum power provided by the external device, thus protecting the circuit from damage.

In order to meet different application requirements, BZW04-154B-E3/73 can be configured with different series resistors, turning the diode into a voltage or current protection device. This diode also features a low clamping voltage to protect the circuit during a power surge. Additionally, the diode is encapsulated in a hermetically sealed package, making it resistant to atmospheric fluctuation.

In conclusion, BZW04-154B-E3/73 is a robust TVS-diode with excellent performance characteristics. It is suitable for applications which require reliable high speed and ESD protection. Its suitable working voltage, current rating and low thermal resistance provide optimum protection for various electronic circuits.
