Transient voltage suppressors (TVS) diodes are semiconductors components that are designed to protect circuits and equipment from over-voltage and over-current electrical transients. The CDDFN2-T3.3B diode is a unidirectional diode designed specifically for over-voltage and over-current protection. It is available in a compact 2-pin lead-free, RoHS-compliant package.

The CDDFN2-T3.3B diode can provide protection against over-voltage transients as high as 30V, and over-current transients as high as 3.3A. It has a low clamping voltage and an ultra-low on-resistance, meaning it can efficiently protect against both over-voltage and over-current events without sacrificing the waveform integrity. It also has excellent surge capability, with up to 18A surge current at 8/20µs pulse.

The CDDFN2-T3.3B diode is suitable for a wide range of applications, such as consumer electronics, networking, automotive, and power supplies. It is also suitable for many automotive applications, such as in vehicle central door locks, anti-theft alarms, engine immobilizers, and more. It is suitable for both DC and AC applications.

The working principle of the CDDFN2-T3.3B is fairly straightforward. When the voltage level on the input exceeds a certain threshold, the diode will be activated and start conducting current, effectively clamping the voltage at the specified clamping voltage level. This limits the amount of voltage that can be applied to the equipment or circuit, while still allowing it to operate normally.

The CDDFN2-T3.3B also has a reverse breakdown voltage of 5.5V, meaning that it can protect against over-voltage events as low as 5.5V and as high as 30V. It has a fast response time of less than one nanosecond, meaning that it can clamp the voltage quickly and effectively. The fast response time also means that the CDDFN2-T3.3B has minimal impact on the performance of the equipment it protects.

The CDDFN2-T3.3B diode is a reliable and effective over-voltage and over-current protection device. It is available in a small, lead-free, RoHS-compliant package, and is suitable for a wide range of applications. It has a low clamping voltage and fast response time, and is able to protect against over-voltage transients as high as 30V and over-current transients as high as 3.3A. Its ultra-low on-resistance and excellent surge capability make it a highly efficient and effective protection device.
