P4KE33CAHE3/53

TVS - Diodes are specialized diodes that are specifically designed to provide protection from high-energy transients from external sources. These devices provide a temporary voltage clamp, protecting electronic devices from electrical stress. The P4KE33CAHE3/53 is a Common Cathode TVS diode specifically designed for protection against surge currents in automotive and industrial applications.

The P4KE33CAHE3/53 is a variant of a Zener diode with a Series Avalanche Combination (SAC) structure. This structure is designed to provide good ESD protection from high voltage transients such as those caused by lightning. This device is designed to be bidirectional, that is, it can protect from transients on either the positive or negative side. It is rated for a maximum peak pulse current of 33A and a maximum peak voltage of 16V. It is capable of withstanding surge currents up to 40A for short periods of time.

The operation of the device is based on the avalanche breakdown phenomenon. The breakdown voltage is determined by doping levels of the N+/N- regions. When the voltage across the device expands to the avalanche voltage, a large number of holes and electrons are created. These are accelerated in the junction and the energy dissipated in the P4KE33CAHE3/53: causes the voltage to drop to its clamping voltage.

The P4KE33CAHE3/53 is used in a variety of automotive and industrial applications. It can provide electrical isolation, protect against EMI/RFI, reduce switching noise, and protect against voltage transients. In automotive applications, it can protect the signal processing equipment from electrical shorts caused by lightning. It can also be used as a snubber in telecommunications systems. The P4KE33CAHE3/53 is also used for point-of-load protection in power supplies.

The P4KE33CAHE3/53 is an effective solution for providing protection from high-energy transients in automotive and industrial applications. Its series-avalanche combination structure is designed to provide good ESD protection from high voltage transients. It is capable of sustaining high pulse currents and can withstand surge currents up to 40A. The P4KE33CAHE3/53 can be used in various applications for electrical isolation, EMI/RFI protection, and reducing switching noise.
