TVS (Transient Voltage Suppressor) diodes are semiconductor devices mainly used for protecting sensitive electronic components from high-voltage surges (transient voltages). The P4KE380CA-G is a type of TVS diode that provides protection from high-voltage/high-current surges, electrostatic discharge, and other destructive transients.

This device is an Unidirectional diode with a breakdown voltage of 380 Volts. It has a low leakage current and high clamping voltage, making it suitable for a wide range of applications including telecommunications, automotive, domestic appliances, computer networks, and general industrial equipment. It is also designed to absorb repetitive surge transients up to a peak pulse power of 24000 W. In addition, it has an operating temperature range of -55 to 125°C.

The P4KE380CA-G is available in two packages, SMA (Small Outline Package) and SMC (Surface Mounted Component). It is easy to install due to its small size, making it ideal for computer networks and automotives.

In order to understand how the P4KE380CA-G works, it is important to understand the principle of operation for a TVS diode. Its function is to essentially act as an open circuit when the voltage across its leads is normal, but then act as a low-resistance, shooting-branch connection when the normal bias voltage is exceeded by a high-voltage surge.

The P4KE380CA-G protects against voltage surges by clamping them at a safe voltage. The device is designed to absorb (dissipate) the energy of the transient voltage. This is done by converting the transient\'s electrical energy into heat. Clamping is the process of limiting the voltage peak of the surge and limiting the current flow, therefore protecting the device from damage.

The P4KE380CA-G is ideal for a wide range of applications, especially those that require protection from high-voltage/high-current transients. It is a reliable and efficient way to protect sensitive electronic components from damage, and it is easy to install due to its small size.
