TVS (Transient Voltage Suppressor) diodes, otherwise known as transient voltage suppressors, are widely used in electronic circuits for providing protection from overvoltage. The MXP4KE91A is a silicon Uni-directional TVS diode, designed to protect industrial and communication equipment from voltage transients induced by lightning and other transient voltage events.

The MXP4KE91A is specially designed to provide exceptional clamping of voltage transients from EN61000-4-5 compliant systems such as telephone systems and power supplies. It is also well-suited for protecting against overvoltage and ESD in communication equipment, industrial equipment, and automotive applications.

The MXP4KE91A has the following characteristics:

• 1.MAXIMUM CLAMPS: 68 A(tp=8/20 μs)
• 2.AVAILABLE CURRENT: 1.2A(tp=10/1000 μs)
• 3.STORAGE CAPACITY: 6.5pF
• 4.RESPONSE TIME: < 1.0 ps

The working principle of the MXP4KE91A is based on a combination of avalanche breakdown and Zener breakdown. When a voltage transient is applied to the device, it breaks down and conducts current, clamping the voltage and protecting the device. The MXP4KE91A has an integrated bypass diode, which shunt the current away from the main diode when the transient is negative. This prevents excessive power dissipation and increases reliability.

The MXP4KE91A also has low capacitance and excellent dynamic impedance characteristics, which enables it to react quickly to minimise the impact of fast transients. The low capacitance makes it ideal for high frequency applications, and the dynamic impedance helps to reduce the effects of inductive and capacitive loading.

In addition to its protection capabilities, the MXP4KE91A has a very low leakage current, making it suitable for use in high-impedance circuits. It also has high surge capability and excellent soldering capabilities, making it easy to use in difficult to access areas.

The MXP4KE91A is designed to the EN61000-4-5 specification and is compatible with RoHS compliant processes. It is UL94-V0 rated, making it suitable for use in applications where fire safety is a major concern.

The MXP4KE91A is a robust and reliable TVS diode, and is an excellent choice for protection from voltage transients and other overvoltage events. It is well-suited for use in communications, industrial, and automotive applications, and offers excellent protection and low capacitance performance.
