TVS - Diodes are an important device in the electronics industry for applications requiring protection from transient voltage and surges. The BZW04-110 A0G is one such device that offers superior protection from electrical transients which can damage valuable equipment or components. In this article, we will examine the application field and working principle of the BZW04-110 A0G.

The BZW04-110 A0G belongs to the MPR series of Transient Voltage Suppression (TVS) diodes. This fast response surge protection device is designed to offer superior transient protection for high voltage lines, such as those used in automotive, telecom, datacom and consumer electronics applications. It is especially suitable for low capacitance, high volume, and low clamping voltage applications. The device is capable of withstanding transients up to the power of 350 W.

The BZW04-110 A0G consists of a glass passivated junction that is optically coupled to a negative-temperature coefficient (NTC) thermistor. This configuration allows for a fast response time in the event of a surge and prevents damage to downstream components. It also features a low, adjustable capacitance, which is ideal for high-speed data and signal lines.

The working principle of the BZW04-110 A0G is based on a Voltage Breakdown (VBD) technology. When a voltage greater than the device breakdown voltage is applied across its terminals, the thermistor’s temperature increases due to the power dissipation. This heat activates the NTC thermistor, causing it to reduce its resistance and increase the current flow through the circuit. This significantly reduces the clamping voltage and prevents damage to the downstream components.

The device also features a reverse leakage current, which is used to effectively limit peak voltage levels. This provides additional protection for downstream components. Additionally, the device has a low capacitance, which helps reduce reflections on signal and data lines, thus reducing EMI or RFI interference.

The BZW04-110 A0G is a versatile device that can be used for a broad range of applications. It is especially suitable for automotive, telecom, datacom and consumer electronics applications. It can also be used in power supplies, portable devices, motors, and appliances, among other applications. The device helps protect connected components from electrical transients and surges, thus preventing damage and increasing reliability.

In conclusion, the BZW04-110 A0G is a versatile and reliable device that offers superior protection from voltage transients and surges. Its NTC thermistor helps reduce the circuit’s clamping voltage, while its low capacitance allows for reduced reflections on high speed data and signal lines. The device is suitable for a broad range of applications including automotive, telecom, datacom, and consumer electronics, power supplies, portable devices, motors, and appliances, among others. These features make the BZW04-110 A0G ideal for protecting sensitive electronics from damage due to electrical surges and transients.
