MX1.5KE47CA Circuit Protection

Transient Voltage Suppressors (TVS) are a common form of Varistors (VARs)—devices designed to protect electronic circuits from voltage spikes. In particular, TVS Diodes are designed to absorb energy from transient signals and either pass the energy out of the circuit, or safely dissipate it from the circuit. One such TVS Diode is the MX1.5KE47CA.

The MX1.5KE47CA is a unidirectional Transient Voltage Suppressor Diode (TVS) designed for use in power transistor systems and motor drivers. It is suitable for automotive, domestic and industrial applications. The MX1.5KE47CA is rated for a peak pulse voltage of up to 1500V, preventing the circuit from overload or destruction by voltage spikes.

The MX1.5KE47CA is designed with a characteristic PN junction that is optimized to have a low forward voltage drop and a low leakage current. It is capable of absorbing up to 500A of peak current, making it suitable for high current applications. It also has a low breakdown voltage, allowing it to operate even with low voltage signals.

The MX1.5KE47CA works by suppressing voltage and providing a fail-safe condition when the voltage reaches a certain threshold. When the voltage passes the specified threshold, the MX1.5KE47CA acts as an open circuit and prevents the current from flowing to the protected circuit. This is achieved by an internal avalanche breakdown that occurs when the voltage exceeds the specified breakdown voltage.

The MX1.5KE47CA also has an integrated protection diode, which provides additional protection from reverse current when the CFB pin is connected to ground. The protection diode also has a low reverse leakage current, meaning that it will allow only a small amount of current to pass through in reverse, thus preventing the circuit from being damaged or destroyed.

The MX1.5KE47CA is an essential component for protecting sensitive electronic equipment from voltage spikes and surge currents. It is suitable for use in automotive, industrial and consumer applications, as it can safely prevent the circuit from overload or destruction. It is also capable of handling high peak currents and has an integrated protection diode for additional safety.
