Transient voltage suppressors (TVS) are used for the purpose of protecting sensitive systems such as electro-mechanical components or electronic systems from exposed high voltage transients. In other words, TVS diodes act as surge protectors that protect equipment against electrical disturbances by clamping down voltage above its breakdown voltage.

The MX1.5KE130CA is a bi-directional transient voltage suppressor (TVS) device with a transient protection rating of 130 V from industry leader SMC (Semtech Corporation). It has a low clamping voltage of 148 V for peak pulse current working up to 1500 A (Ipp) at 10/1000 μs waveforms.

The wide range of operating conditions of the MX1.5KE130CA make it an ideal choice for overvoltage protection against transient peaks in a wide variety of applications such as telecoms & networking, computer peripherals, automotive electronics, consumer electronics, industrial & medical and audio/video equipment.

The MX1.5KE130CA uses PN junctions that have a breakdown voltage specified during the manufacturing process. This breakdown voltage is usually greater than the desired operating voltage of the power system. When the power supply exceeds this breakdown voltage, the PN junction is triggered and the current is allowed to pass through the diode, thereby suppressing the overvoltage.

The primary working principle of the MX1.5KE130CA is to serve as a back-up protection. When the power supply exceeds the breakdown voltage, the diode turns on and conducts a big current, thereby clamping down the voltage to the breakdown voltage. As a result, the excess current is diverted away from the power system, preserving its operating parameters and preventing it from damage.

The MX1.5KE130CA device has very low dynamic resistance, making it suitable for use in automotive and telecommunication systems that require high switching speed and high reliability. Furthermore, its unidirectional design makes it an ideal choice for ESD (electrostatic discharge) applications, providing maximum protection from this kind of damage.

The MX1.5KE130CA device has wide operating temperature range of -55°C to +150°C, making it suitable for industrial and automotive applications. The device also boasts 200 mA continuous reverse current and 085 peak forward current per watt characteristics, making it highly efficient for a range of applications.

In summary, the MX1.5KE130CA transient voltage suppressor (TVS) is an ideal choice for protection against transient peaks and ESD in a range of applications due to its wide range of operating conditions, low clamping voltage, low dynamic resistance and wide operating temperature range. Moreover, its unidirectional design and 200 mA continuous reverse current make it ideal for protection against static discharges for telecommunication and numerous other applications.
