TVS - Diodes

A Transient Voltage Suppressor Diode, or TVS Diode, is a microelectronic device that is used to protect fragile circuits from voltage transients. The most common applications for TVS Diodes are protecting against power surges, ElectroStatic Discharge (ESD), and lightning strikes.

BZW04P128HE3/54 Application Field and Working Principle

The BZW04P128HE3/54 TVS Diode is an advanced protection diode with low capacitance and reverse stand-off voltage. It is designed for lightning strike / ESD protection for up to 6th order harmonics operating in the 400-400MHz range. This device provides bidirectional protection, and it is housed in an SMC package with low capacitance and low inductance.

In terms of the working principle of this TVS Diode, its operation is based on the principle of a Zener diode. This type of diode employs an intrinsic capacitance in order to clamp the voltage surge to a safe level. When exposed to a voltage surge, the intrinsic capacitance of the Zener diode reacts rapidly to absorb the energy of the surge, thus limiting the voltage seen across the diode.

The BZW04P128HE3/54 TVS Diode is suited for a wide range of applications, such as the protection of Telecom and HFC/ CATV transmitters, antennas, and power supplies. It can also be used in automotive, medical, and industrial applications. It features a wide reverse stand-off voltage range from 5 V to 30 V, making it suitable for a wide range of applications.

This TVS Diode also offers a high surge rating of up to 600 W and fast response time of less than 5 ns, which is ideal for effectively handling lightning surge and ESD strikes. Its low capacitance of 0.30 pF makes it suitable for high-speed signal applications such as USB2.0, HDMI, and Ethernet.

The BZW04P128HE3/54 TVS Diode is designed for the highest level of surge protection, while its small case size, low capacitance, and wide stand-off voltage range make it ideal for a variety of applications. With its advanced features and durable construction, it is sure to provide a reliable level of protection for your sensitive electronic equipment.
