MP6KE47AE3

TVS - Diodes

Transient Voltage Suppressors (TVS) diodes are a type of semiconductor device, typically a diode, that is designed to protect electronic components from voltage overload due to surges or transients. They contain a built-in breakdown voltage structure that ensures that the device will fail if the voltage level exceeds the specified breakdown voltage.

MP6KE47AE3 is a unidirectional TVS diode used for ESD, transient and load dump protection. It is designed to protect motor controllers, DC-DC converters and other circuits from transients generated by load dump, ESD, lightning or other sources. The device provides an ESD protection level of up to 8 kilovolts (kV) and is RoHS compliant.

MP6KE47AE3 has a wide range of application fields including automotive, automotive electronics (especially motor controllers), Portable electronics, and consumer electronics. It can also be used in general industrial and prototyping applications.

The working principle of MP6KE47AE3 is based on the concept of avalanche breakdown, where a large number of charge carriers are injected in the junction’s depleted region, leading to a large increase in current. In the fast voltage transition process of high transient or ESD voltage, the device will breakdown and divert the transient current into the safe ground.

MP6KE47AE3 consists of a diode junction structure, which consists of a P-type substrate and an N-type epitaxial layer which forms a depletion zone between them. The built-in breakdown voltage is determined by the geometry of the junction. When the high voltage is applied to the diode, the electrons and holes move into the depletion zone and form interface states, resulting in a sharp increase in current.

MP6KE47AE3 has several advantages to offer, including:

• High ESD protection level up to 8kV
• Low leakage current
• Fast response time
• High surge current capability
• Low junction capacitance

MP6KE47AE3 is a very versatile device, and can be used in a variety of applications where transient protection is needed. It can be used in automotive, motor control, communications, and consumer electronics applications, to name a few. It is also RoHS compliant, so it can be used in any region.

In summary, MP6KE47AE3 is a unidirectional TVS diode designed for ESD, transient and load dump protection. It provides a high ESD protection level of up to 8kV and a fast response time. Its application fields include automotive, motor control, communications, consumer electronics and general industrial applications. Its working principle is based on the concept of avalanche breakdown.
