ADG467BRSZ Circuit Protection

ADG467BRSZ is a family of TVS (Transient Voltage Suppressor) diodes that are designed to protect against overvoltage and ESD (Electrostatic Discharge). It is a mixed technology device which combines the advantages of the Diode and Transistor technologies and is a single chip integrated circuit. This device is widely used in many industries such as communication, automotive, and consumer.

The ADG467BRSZ incorporates a diode voltage clamp with a transistor base stage. This type of TVS prevents any high voltage spike from damaging sensitive devices attached to it. It offers surge protection with very low capacitance and very fast response time. The fast response time is much higher than that of a diode-based TVS. The low capacitance and the fact that the device is housed in a SOT-323F package makes it attractive for high speed data rate applications.

The working principle of the ADG467BRSZ is that the diode connected in series across the power supply rail acts as a voltage limiter. When the voltage across the diode exceeds the breakdown voltage (Vbr), the diode starts to conduct current and thus limits the voltage across the power rail. The transistor stage assists this process to ensure a fast and effective clamping action.

The device has a maximum reverse voltage of 6.5V and Peak pulse current rating of 1.2A (Ipp). It is a robust and reliable device that can be used for high speed data rates applications such as USB, HDMI, Video, Ethernet, etc. It also supports ESD protection and is ideal for safety applications such as automotive electronics and communication devices.

The ADG467BRSZ is used as a protection component to prevent the damage caused by sudden power surges and power spikes. It is used in power supplies, communication systems, industrial controls, medical devices, consumer electronics, and many other applications. The device can also be used to protect against ESD events.

The ADG467BRSZ is a low cost, reliable, and efficient device that provides robust protection against overvoltage and ESD. It is a mixed technology device that combines the advantages of the diode and transistor technologies and is easy to integrate into any system. The fast response time and low capacitance make it attractive for high speed data rate applications. It is widely used in many industries such as communication, automotive, consumer and safety applications.
