TVS - Diodes are electronic components that protect other devices and circuits from sudden surges of abnormal voltage and current. Transient voltage suppression (TVS) diodes, also known as surge suppression diodes, are utilized on circuits to prevent high-voltage pulses or surges from damaging components on the circuit. The BZW04-26-E3/73 is a highly efficient TVS – Diode designed for a variety of applications where protection from transient voltages is needed, including automotive, telecommunications, consumer electronics, and industrial applications.

The BZW04-26-E3/73 features low leakage current, fast response time, and low reverse-recovery voltage. The TVS-Diode is designed to withstand a maximum peak pulse power of 1500W without any failure. It also has a low operating voltage, making it suitable for applications that require a low voltage drop. The BZW04-26-E3/73 also features excellent surge capability and withstands voltage between -5V and +20V. Additionally, the device features an ESD protection of up to 25 V HI and -5 V LG.

The BZW04-26-E3/73 is typically used in automotive, telecommunications, consumer electronics, and industrial applications where transient overvoltage protection is necessary. The diode is primarily used in AC/DC power conversion circuits, DC/DC converters, inverter circuits, automotive and industrial control circuits, and battery management systems. The TVS-Diode also provides protection from overvoltage, overcurrent, and ESD events in various types of signal lines, such as telecommunications lines, Ethernet, VGA, and USB.

The working principle of the BZW04-26-E3/73 is based on the breakdown voltage characteristics of its junction. It utilizes a Zener diode to handle electrostatic discharges (ESD) by conducting the spike current through an extremely fast breakdown. If a surge current of more than 1.5A exceeds the diode’s reverse voltage rating, the diode will break down, allowing the current to pass without damaging the protected circuit. When the surge subsides, the diode returns to its normal mode of operation.

The TVS-Diode also utilizes the avalanche breakdown voltage of the diode to protect the circuit from overvoltages. If the voltage on the line exceeds the avalanche breakdown voltage, the diode switches to a highly conducting state and shunts the excess voltage away from the protected circuit. When the transient voltage passes, the diode returns to its previously stated reverse voltage rating.

In conclusion, the BZW04-26-E3/73 is an efficient and reliable transient voltage suppression diode designed for automotive, telecommunications, consumer electronics, and industrial applications where protection from transient voltages is needed. The device is capable of operating in a wide range of temperatures and conditions, and has an ESD protection of up to 25 V HI and -5 V LG. Its primary working principle is based on the breakdown voltage characteristics of its junction, and utilizes a Zener diode and avalanche breakdown voltage to conduct the spike current and shunt the excess voltage away from the protected circuit, respectively.
