The MAP4KE30A is a type of Transient Voltage Suppressor (TVS) Diode. Commonly used for providing protection to electrical and electronic systems from damaging surges. It is unidirectional, so the current will only flow through in one direction. A reverse-biased diode will not pass any current until the voltage reaches a certain level, called the Peak Reverse Voltage rated. The MAP4KE30A has a Peak Reverse Voltage of 30V.

The MAP4KE30A can be used in a number of consumer and industrial applications. It can be used for data line protection, surge detectors for providing protection against over-voltage, and it can provide proof against electrostatic discharge (ESD). In circuit protection, the MAP4KE30A can be used to protect mobile phones, a wide range of consumer electronics and home appliances, and even IT equipment like routers and switches. MAP4KE30A is also suitable in mains protection and noise protection. An automotive grade version of this device is available. Additionally, as a 30V TVS diode, the MAP4KE30A can be used in many automotive applications. These include circuit protection for audio systems, horns, wipers, lights, and high voltage systems.

The MAP4KE30A has a fast response time, which allows it to react quickly to transient disturbances, limiting peak pulses and clamping voltages. It also features low capacitance, so it can be effective in high frequency applications. The stand-off voltage of the MAP4KE30A is 5.5V, which ensures that circuit protection in lower voltage applications is still effective. Finally, the MAP4KE30A is RoHS compliant, suitable for lead-free installations.

The MAP4KE30A works in a simple way. When the voltage rises to a particular value, the device turns ‘on’ allowing the excess voltage to flow through the diode. The reverse bias of the diode amplifies the current, which then serves to clamp the voltage. This helps to protect the circuit and the devices being connected to it.

The MAP4KE30A from ON Semiconductor is a 30V unidirectional TVS diode that provides reliable protection against transient surges. The great combination of features such as fast response time, low capacitance and RoHS compliance, make the MAP4KE30A ideal for a wide range of consumer and industrial applications.
