TVS ( Transient Voltage Suppressor ) diodes are widely used in many applications to protect sensistive electrical components against sudden voltage spikes. The 5KP33C is a popular TVS diode, which provides optimum protection against power surges of up to 33V. The device is capable of withstanding high surge currents, up to 180A with rise times of 10/1000μs.

Application Field of 5KP33C

The 5KP33C is most commonly used in electronic products such as PCs, telecom equipment, communication devices, power supply units, industrial controllers, and automotive electronics. It provides overvoltage protection against power surges of up to 33V. The device is designed to clamp voltage at a safe level, eliminating the need for bulky surge protection components. It is also well-suited for applications where peak surge currents must be limited, such as automotive electrical systems.

Working Principle of 5KP33C

The 5KP33C is designed as a two-terminal, bi-directional device that operates based on a breakdown mechanism. When voltage is applied to the diode, the device will reach a certain breakdown voltage, VBR, and clamp the voltage at that level. This is known as voltage clamping, which is the main function of the 5KP33C. As the voltage increases, the device will reach its maximum clamping voltage and remain at that level until the voltage drops below the clamping voltage, VCL. As soon as the voltage drops below the clamping voltage, the device will start to conduct current, allowing the overvoltage to be dissipated. This is known as current limiting. The 5KP33C has a maximum peak power rating of 200W and a maximum clamping voltage of 33V.

Conclusion

The 5KP33C is a popular two-terminal, bi-directional TVS diode that provides over-voltage protection against power surges of up to 33V. It is most commonly used in electronic products such as PCs, telecom equipment, communication devices, power supply units, industrial controllers, and automotive electronics. The device works based on a breakdown mechanism, where voltage is clamped at a safe level and current limiting is achieved when the voltage drops below the specified clamping voltage. The 5KP33C offers excellent protection in a range of application fields and is an excellent choice for protecting sensitive electrical components against sudden voltage spikes.
