TVS – Diodes, which are also known as surge protection diodes, are an important component in many electronics and circuits. Their purpose is to provide protection against transient over-voltages, to prevent damage or destruction to electronic components. The BZW04-85 B0G, or Bidirectional Transient Voltage Suppressor, is one such type of diode.

The BZW04-85 B0G diode is a bidirectional breakdown diode, designed to clamp positive and negative voltage transients. It has an operating voltage of 8.5V and breakdown voltage of 9.5V, meaning that, in the event of a large voltage spike, the diode will conduct current and reduce the magnitude of the spike. It has a current limiting capability and low clamping voltage for high energy transient suppression.

The BZW04-85 B0G is commonly used in automotive applications, such as in power distribution systems, fuel system control systems, ignition systems, and engine control systems. It can also be used in other industries, such as telecommunications and medical applications. The diode is well-suited to these uses as it offers high transient energy dissipation, low leakage current, and low capacitance. It also has a low profile, making it suitable for applications with limited space, as is often the case with electronic automotive components.

In operation, the BZW04-85 B0G provides protection by clamping the voltage at 9.5V during transient over-voltage events. This limits the amount of current that can pass through the diode and thus protects the electronics from being damaged or destroyed. The clamping voltage also helps to limit electromechanical failures that can occur due to transient over-voltage events. The BZW04-85 B0G also has a reverse breakdown voltage of 4.5V, meaning that it will not allow current to pass through it until the voltage applied to it reaches 4.5V. This feature helps to protect the diode from being damaged in the event of a large spike in reverse polarity.

Overall, the BZW04-85 B0G is an ideal choice for applications where transient over-voltage protection is required. Its features make it well-suited to automotive, telecommunications, and medical applications, where it can provide reliable protection against voltage transients. It is also highly reliable and cost-effective compared to other types of transient voltage suppressors.
