Transient Voltage Suppressors (TVS) Diodes are a type of semiconductor diode designed to protect electronic devices from damage caused by transient voltage conditions. The MAP4KE91AE3 is a general-purpose unidirectional Transient Voltage Suppressor (TVS) Diode designed for ESD and surge protection. This diode is capable of protecting various application fields from overvoltage spikes, such as over-the-air antennas, computer busses, and cellular base stations.

The MAP4KE91AE3 is designed with a common cathode configuration and features 800 Watts peak pulse power dissipation at a 45V standoff voltage. It offers high surge capability at low operating voltages of 5V and 25V, making it highly versatile and suitable for a wide range of applications. Furthermore, its reverse leakage current of 10 nA at 25V helps to provide a power supply with surge protection.

The working principle of the MAP4KE91AE3 is designed to protect electronic circuits from transient voltage conditions, such as electrostatic discharge (ESD) and electro-magnetic disturbances. The device is composed of four diode configurations connected in parallel. When there is an overvoltage or transient voltage condition, the diode’s avalanche voltage is exceeded and it begins to act as a low-impedance switch between the drain and the source. This causes the voltage across the device to drop and protect the electronic circuit from excessive voltage. This process is known as clamping, it is the principle by which tv’s diodes protect electronic circuits from damage caused by transient voltage conditions.

In summary, the MAP4KE91AE3 is a general-purpose unidirectional Transient Voltage Suppressor (TVS) Diode designed for ESD and surge protection. Its working principle of protecting electronic circuits from transient voltage conditions is based on clamping technology and it features 800 Watts peak pulse power dissipation at a 45V standoff voltage. The MAP4KE91AE3 is suitable for a wide range of applications and is capable of providing stable surge protection to electronic devices.
