TVS (transient voltage suppressor) diodes are useful in protecting components and systems from fatal breakdowns due to high voltages, and 5KP33CAE3/TR13 is an example of such diodes. It is additionally used to protect equipment from current and electromagnetic interference.

Application Field

The 5KP33CAE3/TR13 is capable of providing bidirectional ESD protection, and it is used to protect against overvoltage transients in low- and high-side applications. It is designed to protect circuits from Electrostatic Discharge (ESD) which is caused by the difference between the surface of two electrical components handling electrical charge (electrically charged human bodies or vehicles, machinery, and structures). The device is primarily used in automotive applications (ABS, instrument panel, door modules, wiring harnesses, etc.), and consumer electronic devices (mobile phones, portable audio players, controllers, etc).

Working Principle

When the 5KP33CAE3/TR13 is exposed to potentially damaging voltage, electric current flows through it and dissipates electrical energy without causing damage to the equipment or components. This diode is an electro-optical semiconductor device which is designed to protect against overvoltage transients, and it operates using the Avalanche breakdown phenomenon. When the voltage applied across these devices reaches a certain point, called the breakdown voltage, an avalanche of free electrons is produced which causes the diode to rapidly change from a highly resistive to a very low resistive state.

The 5KP33CAE3/TR13 also has a protection input protection mechanism which prevents excessive current from flowing through the device, and which protects the device from short-circuiting. This input protection mechanism helps prevent the device from overheating, and helps protect the device and the components connected to it from permanent damage.

When a TVS diode is exposed to voltage spikes, the device is able to quickly divert the spike onto its own designed path. This path diverts the current away from the components connected to it, thus preventing any damaging surges from entering the component. In the case of the 5KP33CAE3/TR13, the device is able to divert the surge while operating at an extremely low voltage drop across it.

The 5KP33CAE3/TR13 is an ideal choice for protecting devices and components from fatal breakdowns due to high voltages and current surges. It operates using the Avalanche breakdown phenomenon, and it has an input protection mechanism which helps protect it and the components connected to it from permanent damage in the event of a surge. Additionally, it is suitable for use in low- and high-side applications in automotive and consumer electronic devices, and it has a low voltage drop across the device.
