Transient Voltage Suppressor (TVS) devices are a form of solid state protection against over-voltage transients. The IXBOD1-25R TVS devices employ a combination of Zener diode and avalanche breakdown mechanisms of protection to protect against ESD, EFT and surge overvoltages.

IXBOD1-25R devices are well suited for general purpose surge protection requirements in automotive, industrial, consumer and telecom applications. They are RoHS compliant and provide ESD and surge protection function up to 25V. The IXBOD1-25R devices also have low surge current capability, low clamping voltage and provide robust durability with no derating requirement up to 8kV.

The IXBOD1-25R device adopts a variety of materials and technology to provide a multi-level solution against transient voltages. These components are made up of a combination of Zener and avalanche breakdown mechanisms of protection. It employs unique avalanche breakdown techniques which increase avalanche energies with increased electric field. This technique hence overwhelms the Zener action on transients, thus allowing the device to provide additional ESD protection.

The device has a wide operating temperature range from -55°C to +125°C. It can also withstand high peak power rating of 100W. It is also current limited and features low dynamic impedance. Its low signal distortion and clamping voltage is less than 25V. The system also provides noise reduction combined with surge protection.

The working principle behind the IXBOD1-25R device is based on the concept that the Zener action is overwhelmed by the avalanche breakdown action on transients. This event occurs when the electric field strength of the avalanche device reaches a certain level, allowing the avalanche mechanism to provide additional ESD protection.

When the normal circuit voltage is exceeded, the avalanche break down will be activated. This causes the current to divert either into or out of the device, depending on the polarity of the voltage. This will protect the system against overvoltages.

The IXBOD1-25R devices have a wide range of applications including automotive, industrial, consumer and telecom. These components can be used in automotive ignition systems, for in-vehicle navigation devices, audio amplifiers, video switches and camera modules, as well as telecom applications such as switching regulators, USB ports, and 3GPP modules.

In conclusion, the IXBOD1-25R device is a mixed technology based protection component which provides a reliable solution against overvoltage transients. It employs both the Zener and avalanche breakdown mechanisms of protection, allowing it to provide protection up to 25V. Its wide applications make it an ideal choice for automotive, industrial, consumer and telecom solutions.
