TVS (Transient Voltage Suppression) diodes are semiconductor devices, used for suppressing high voltage pulses. P4KE110CA-E3/73 also belongs to the TVS family of products, and is used for protecting electronic equipment against electrostatic discharge (ESD) transients caused by lightning, machines, and other sources.

The P4KE110CA-E3/73 TVS diode has a peak pulse power rating of 110 W (10/1000 µs). It has a highly reliable and high surge current capacity of 10 kA @ (8/20 µs) waveform with a low 5 % maximum clamping voltage of 74 V. It is designed to protect semiconductor devices from electrostatic discharges (ESD) up to the level of 25 kV (IEC61000-4-2).

Applications for the P4KE110CA-E3/73 include protection of electrical and electronic systems from high voltage transients, such as those generated by lightning or power line surges. It is also suitable for protecting automotive electronic systems and can be used in the telecom, industrial, and consumer electronics industries.

The working principle of the P4KE110CA-E3/73 diode is based on the principle of a Zener diode. When there is an over voltage, the reverse breakdown voltage of the diode is exceeded and a large reverse current begins to pass through the diode. This current is conducted through the diode from the anode to the cathode. This current, in turn, causes the voltage across the diode to drop to its rated voltage, thereby protecting the circuit from the over voltage.

P4KE110CA-E3/73 offers low dynamic resistance for optimal clamp performance and fast response time. It also provides very low leakage current, low capacitance, and a very stable performance over temperature and current. The P4KE110CA-E3/73 is designed for surface mount technology, and the package size is only SOD -123. This allows for a smaller footprint for maximum designer flexibility.

In conclusion, theP4KE110CA-E3/73 is a highly capacitive and reliable transient voltage suppress diode, designed for protecting electrical and electronic systems from harmful transients. It is suitable for a wide range of applications, from automotive electronics to telecommunication devices, offering superior electrical performance and exceptional thermal stress reliability.
