TVS - Diodes, or transient voltage suppressors, are semiconductor protection devices used for protection against transients and surge voltages. CPDTR0312V0U-HF is one such device.

The CPDTR0312V0U-HF is a three-terminal device that is capable of providing advanced ESD protection for sensitive electronic circuits. With its built-in EMI/RFI filtering, it can enhance the EMI/RFI noise immunity of an electronic system.

This device is ideal for automotive, industrial, and consumer applications. It is a robust and reliable protection device that provides surge and ESD protection for data lines, such as USB, CAN, or LIN. The device can also be used in telecommunications, automotive, and consumer electronics for electrostatic protection.

The CPDTR0312V0U-HF has a breakdown voltage of 3.12V and a maximum working voltage of 2.7V. It can sustain a peak pulse power of 100W (10/1000μs) and has a low reverse leakage current of ≤ 100nA at reverse voltage. The device is rated for an extremely high surge current of 100A (8/20μs) and a maximum clamping voltage of 6.7V. This device is available in a small SOD-323 package measuring just 2.52mm x 1.20mm.

The working principle of the CPDTR0312V0U-HF is based on the avalanche breakdown effect. The device contains a special PN junction, which is designed to have a predictable voltage characteristic. When the applied voltage across the device exceeds its breakdown voltage, electrons in the device begin to move into the Avalanche region. This produces an avalanche current, which is limited by the on-state resistance of the device. This current flow causes the voltage across the device to be clamped to a certain level, thus providing ESD and surge protection.

The CPDTR0312V0U-HF is a highly effective ESD and surge protection device for a variety of applications. It is small, reliable, and provides superior safety and performance characteristics. It is capable of providing reliable protection against transients and surge voltages, making it an ideal choice in automotive, industrial, and consumer applications.
