MP4KE30CA

TVS-diodes are a type of semiconductor junction which provides protection from electrostatic discharge (ESD) as well as electrical overstress (EOS). The MP4KE30CA is a 30V bidirectional transient voltage suppressor, which is commonly used to protect electronic systems from transient voltage surges. The MP4KE30CA is especially suited for applications requiring a high surge capability and fast response.

The MP4KE30CA is constructed using a vertical double-diffused metal-oxide-semiconductor (DMOS) structure and utilizes the avalanche breakdown phenomenon. This structure increases the breakdown voltage and ensures a high current capability without operation under short-circuit conditions. The MP4KE30CA is available in two package types, the 8-pin DIP (dual in-line package) and the 8-pin SOP (small outline package).

The MP4KE30CA provides ESD protection by suppressing both positive and negative transient voltage surges. When a surge above the breakdown voltage is applied across the diode, the region of the junction breaks down and allows current to pass through. This reduces the potential voltage and protects the circuit from damage. The reverse breakdown voltage, or peak inverse voltage (PIV), of the MP4KE30CA is 30V. This means the diode can withstand up to 30V of transient voltage without damage.

The MP4KE30CA also provides EOS protection. When a surge beyond the rated current is applied across the diode, the junction heats up and the current is limited. This limits the amount of power dissipated in the junction and protects the circuit from damage. The maximum peak working current of the MP4KE30CA is 30A. This means the diode is capable of withstanding up to 30A of surge current without damage.

The MP4KE30CA is well-suited for protecting integrated circuits, digital systems, and audio/video systems from transient voltage surges. It can be used in a wide variety of applications, including automotive systems, medical equipment, consumer electronics, and industrial equipment. The device is capable of operating over a wide temperature range and is RoHS compliant.

In summary, the MP4KE30CA is a 30V bidirectional transient voltage suppressor designed to provide protection from ESD and EOS. The device utilizes a DMOS structure and avalanche breakdown to provide superior surge performance, while the PIV and peak working current ratings ensure a high level of protection. The MP4KE30CA is well suited for a variety of applications and environments.
