TVS - Diodes

MAP4KE56CAE3 is a unidirectional, silicon based TVS (transient voltage suppressor) diode. Its main purpose is to provide overvoltage protection for electronic components. It has an array of applications in today’s fast-paced electronic industry, including computers, mobile phones, consumer electronics, automotive equipment, medical-grade products, and more.

Basic Characteristics

MAP4KE56CAE3 has a maximum power dissipation of 400 watt, a peak pulse current of 54A, a reverse clamping voltage of 56V, and a peak pulse power rating of 600W. It has an operating junction temperature of -55°C to +125°C with 35mOhm of on-state resistance. The device can withstand a transient voltage of up to 80 Volts and a surge current rating of up to 100A. It also features a breakdown voltage of 56 Volts with reverse current leakage of less than 1mA.

Application Fields

MAP4KE56CAE3 is mainly used in consumer electronics, medical electronics, automotive electronics, communications, industrial electronics, high-power electronics, networking solutions, telecom equipment, embedded systems, and other sensitive electronic systems. It is also used in various devices that require transient voltage protection, such as those exposed to surges in lightning or locations near electrical power meters.

Working Principle

MAP4KE56CAE3 is equipped with an array of avalanche components that limit peak pulse-current during transient overvoltage events. When a reverse voltage greater than 56 volts is applied, the avalanche components break down and thus allow a current to flow. As the current continues to flow, the voltage across the device is clamped at a certain level. This process prevents further increase in voltage and it reduces the peak transient current, protecting the device from any damage.

After this process, the device goes back into its normal state and the current returns to its original level. This fast and simple protection mechanism ensures optimal level of protection for the device. The device is also designed to keep up with rapid change in technology and thus offers high reliability in harsh environment.

Conclusion

MAP4KE56CAE3 is an effective and reliable silicon-based TVS diode providing overvoltage protection of various electronic components and devices. It is used mainly in consumer and commercial electronics due to its high reliability and fast protection mechanism.
