The TVS diodes (Transient Voltage Suppressors) is a device designed to protect voltage sensitive components from high voltage transients such as electrostatic discharge (ESD), other temporary over voltage spikes, and power surges from lightning or AC line. BZW50-12B is type of TVS, which has a wide range of applications such as computers, industrial, telecommunications, automotive, consumer, and automotive electronic equipment, among others.

BZW50-12B is a unidirectional diode, which means it only allows current to flow in one direction, allowing the electrical charge to build up in a reverse direction until it reaches its breakdown voltage. When the voltage applied to a TVS diode becomes greater than the breakdown voltage, current begins to flow, diverting the transient energy away from any sensitive circuitry being protected thereby protecting it from impact of the surge/transient energy. The TVS diodes of this device are available in different package styles and with a variety of voltage ratings.

The working principle of BZW50-12B is quite simple. When the breakdown voltage of the diode is reached, the device creates an avalanche breakdown, which then limits the energy of the transient voltage surge. This ensures that the surge energy is discharged safely while protecting the electronic components from damage. The TVS diode is then designed to discharge the stored energy in the process of circuit conductivity.The basic elements in the design of the BZW50-12B are:

• Avalanche diode
• Internal clamps
• The Zener section
• Lead inductance

The avalanche diode works by creating a conductive path when the reverse breakdown voltage is reached, allowing the current to flow without damage. The clamp then functions to reduce the surge current and limit the peak magnitude. The Zener section works to absorb the excess energy in order to protect the avalanche diode. Finally, the lead inductance works to reduce the high frequency components of the transient energy, which otherwise causes malfunction in the circuits.

BZW50-12B TVS diodes are used in a variety of applications, such as overvoltage protection for automotive, telecommunications, industrial, and consumer applications. This type of TVS diode is also used for protecting the ground line from ESD, and for making sure that the connection between the two components and the ground doesn’t carry too much current. In addition, these diodes can be used in power supplies, as they are suitable for suppressing EMI-like signals.

The BZW50-12B TVS diode is designed to offer superior performance and reliability in high frequency signal processing applications. This device is highly effective in providing over-voltage protection against ESD, EMI, surges, lightning and power transients. It can also be used to protect against current surges. The BZW50-12B TVS diode is an excellent choice for designers wanting to protect their electronic equipment in a reliable and cost effective way.
