TVS - Diodes

SMBG9.0HE3/52 Application Field and Working Principle

TVS - Diodes are electrical components designed to protect sensitive electronic components and systems from transient voltage and current spikes. They typically have a reverse breakdown voltage that is greater than the designed operating voltage of the system. The SMBG9.0HE3/52 is a low capacitance, high reliability TVS diode specifically designed to protect against high transient voltages and currents.

Application Field

The SMBG9.0HE3/52 is commonly used in applications such as cellular phones, portable electronic equipment, and computers. It is specially designed to protect data and signal lines from damaging transient voltages and currents. It is often used to protect device inputs and outputs from overvoltage conditions. The device can withstand temperatures ranging from -65°C to +125°C and is rated up to a peak voltage of 6.5 V.

Working Principle

The SMBG9.0HE3/52 consists of a Zener diode and a MOSFET. When the voltage across the Zener diode exceeds a certain level, known as the breakdown voltage, it will conduct current, and the MOSFET will turn on, allowing the current to pass through to the device. This device includes a low capacitance rating, meaning that the device will have a fast response time, so it can quickly sense and respond to transient voltage and current spikes.

In addition to its protective circuitry, the SMBG9.0HE3/52 also includes some additional features such as an ESD protection up to ±16 kV and an EMC protection up to ±2 kV. The device is also RoHS compliant and designed with an integrated ESD protection on both sides of the chip.

Conclusion

The SMBG9.0HE3/52 is a low capacitance, high reliability TVS diode designed to protect against high transient voltages and currents. It is used in a wide range of applications including cellular phones, portable electronics, and computers, and includes a number of features such as an ESD protection and an integrated ESD protection on both sides of the chip. The device is rated up to 6.5 V and is suitable for temperatures ranging from -65°C to +125°C.
