BZW04-23 A0G

TVS - Diodes are a type of over-voltage protection component, developed to protect sensitive electronic circuits from damage caused by large electrical transients. The BZW04-23 A0G devices, in particular, are a type of Transient Voltage Suppressor (TVS) clamp, and they are designed to protect 60V power distributions in industrial applications.

The electrical principles behind these devices are simple, but effective. The BZW04-23 A0G have two important characteristics: a breakdown voltage VBR, and an effective working voltage WH. WH is the maximum voltage which the device can withstand, while VBR is the voltage at which the device starts to conduct (clamp).

In operation, when the voltage across the TVS device is less than the WH, it behaves like an open switch, allowing little or no current to flow. However, when the voltage across the device exceeds the WH, the breakdown voltage of the device is reached, and the device acts as a short, effectively reducing the voltage across the device back to WH. By doing this, excessive voltages which may be present on the power distribution are attenuated, preventing damage to sensitive components which may be connected to the power lines.

The BZW04-23 A0G is designed to provide over-voltage protection for applications powered by 60V DC power, and can be used in industrial circuits, such as control systems and motors. The device has an effective working voltage of WH= 58.3V, and a breakdown voltage VBR= 63V at 25°C. It is highly effective in combating electrical transients that may be present in the power lines, and its wide operating temperature range of -40°C to +125°C makes it suitable for a variety of industrial applications.

In summary, the BZW04-23 A0G Transient Voltage Suppressor (TVS) clamp is a reliable and effective device that can be employed to protect 60V power from damage caused by electrical transients. Its wide operating temperature range and reliable breakdown performance make it a popular choice for designers who require reliable over-voltage protection in their industrial applications.
