TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are surge-protectors, designed to protect equipment from transient voltages, also known as ESD (electro-static discharge). These devices act as an alternative to more traditional overvoltage protection components, such as fuses, transient suppressor circuits, and others. They provide high speed, low-leakage protection for many electronic applications, including automotive, military, space, medical, telecommunications, industrial, and consumer electronics.

BZW50-56 application field and working principle

The BZW50-56 series of Transient Voltage Suppressor (TVS) Diodes is designed for use in a wide variety of applications, including automotive, military, industrial, and consumer electronics. It is rated to operate at a wide range of temperatures from -40℃C to +85℃C and is available in a variety of package sizes and lead configurations. The BZW50-56 series of TVS diodes protect equipment from transient voltages in applications such as overvoltage, electrostatic discharge (ESD), and electrical transients.

The working principle of the BZW50-56 is based on a reverse-biased diode that is designed to divert current away from sensitive components in the event of an overvoltage. The diode is reverse biased, so current will not flow through the diode unless subjected to a transient voltage greater than its reverse breakdown voltage, which is typically around 5-15V. When a voltage greater than the breakdown voltage is applied, a surge of current will flow through the diode and be dissipated in the form of heat. This action provides protection for sensitive components from overvoltage transients.

The BZW50-56 series of TVS Diodes is designed to protect electronic circuits from electrical transients and ESD. The diodes are rated at 5V, 12V, 15V, and 20V and are available in a variety of package sizes and lead configuration options. The TVS Diodes are based around a reverse-biased diode that will only allow current to flow when a voltage greater than its reverse breakdown voltage is applied. The device will absorb and dissipate the surge of current, providing protection for sensitive components from overvoltage transients.
