The BZW04-171B A0G is a TVS – Diode component, which is designed to protect against ESD and overvoltage. The device is capable of suppressing up to 24A current. It has a peak pulse power rating of 380W and an operating temperature range of -55°C to 150°C. It is a surface mount device which requires a pad area of 7.95×2.38mm, with a lead pitch of 0.95mm.

Applications

The BZW04-171B A0G is used in a variety of applications, such as: * Automotive electronics* Uninterruptible Power Supply (UPS) systems* Industrial control systems* Telecommunications systems* Portable electronicsThe device is also used to provide surge protection in power supplies and lighting systems.

Working Principle

The BZW04-171B A0G is designed to suppress surges and protect against electrostatic discharge. It operates on the principle of reverse breakdown, where a voltage is applied across a diode and, when this voltage reaches a certain point, known as the breakdown voltage, a large current flows through the diode. This current is designed to reduce the incoming voltage and protect the target device from overvoltage.The device is designed to be mounted on a PCB. The common mode component of the transient is suppressed by the guard ring network, which is located around the device to prevent interference. The device is designed to have a low capacitance, which improves its response time and reduces the amount of ringing.

Conclusion

The BZW04-171B A0G is an example of a TVS – Diode, which is designed to provide surge protection and protect against ESD. It is suitable for use in a range of applications, such as automotive electronics, industrial control systems, and telecommunications. The device operates on the principle of reverse breakdown, where a large current flows through the diode when a certain voltage is reached. The device has a guard ring network which improves its performance, and a low capacitance for improved response time.
