When it comes to protecting electronic circuits from voltage transients and overstress, TVS (transient voltage suppressors) are a widely-used technology. However, many electronic circuits today require more efficient protection and more reliable operation. Mixed-technology devices, like IXBOD1-18R, are designed to provide a higher level of protection in an integrated package. This document discusses the application field and working principle of the IXBOD1-18R.

The IXBOD1-18R is a two-terminal overvoltage protection component with overvoltage and overcurrent protection, ultra-low capacitance ESD protection, and low leakage clamping performance. The device has a breakdown voltage of 18 volts and a maximum clamp current of 100 mA, making it suitable for a wide range of applications. Additionally, the IXBOD1-18R has a low capacitance of less than 2 pF, resulting in less interference with signals passing through the device.

The IXBOD1-18R uses a combination of technologies to provide its high level of protection. The device combines a Zener diode, which provides the fast response required for overvoltage protection, with a P-channel FET and a resistor array. The Zener diode is connected in reverse polarity, so the device will turn on when the voltage across the diode reaches the breakdown voltage of 18 V. The P-channel FET will draw current from the power supply and the resistor array will dissipate the remaining energy to ground. The device will act as an open circuit until the voltage reaches the breakdown voltage.

The IXBOD1-18R is designed to provide a high level of protection for a wide range of applications, including portable electronics, office equipment, and automotive electronics. It can be used to protect against transients caused by electrostatic discharge (ESD), electro-magnetic interference (EMI), and other overvoltage events. The device is also suitable for low-power applications, such as providing additional protection for logic circuits.

The IXBOD1-18R is well-suited to a wide range of applications due to its combination of fast response, high level of protection, low capacitance, and low-power applications. The device provides fast response to transient events, and its low capacitance ensures that signals passing through the device are not degraded. Additionally, the integrated P-channel FET and resistor array provide reliable overcurrent and overvoltage protection. Furthermore, the device is well-suited to low-power applications, thanks to its low capacitance and the integrated P-channel FET, which protects against overcurrent.

In conclusion, the IXBOD1-18R is a mixed-technology overvoltage protection component suitable for a wide range of applications. It combines the fast response of a Zener diode with the added protection of a P-channel FET and resistor array, providing reliable overvoltage and overcurrent protection. The device is also suitable for low-power applications, thanks to its low capacitance. The IXBOD1-18R provides a high level of protection for a wide range of applications, making it an ideal choice for protecting electronic circuits from transient voltage and overstress.
