TVS (Transient Voltage Suppressor) diodes are a type of semiconductor device employed in numerous applications from protecting an electronic circuit from damaging over-voltage conditions. TVS diodes are typically used to defend against destructive electrical transients such as electrical induced spikes. A well-known type of a TVS diode is the CPDER5V0. This article will explore the application field and working principle of the CPDER5V0 in detail.

CPDER5V0 is a low-cost unidirectional TVS diode specifically designed to protect circuits from low-level overvoltage and transient or surge-induced damage. It helps in providing transient protection from external electric power strike, lightning or electrostatic discharge (ESD). The CPDER5V0 can sustain multiple transient strikes and has a peak pulse power rating (TPP) of 2500W at 100µs. It has a breakover voltage of 5V and a reverse breakover voltage of 4V. It has a maximum clamping voltage of 10V and it can protect circuits up to a maximum surge current of 3A.

CPDER5V0 finds applications in the automotive industry for use in circuits that require high reliability and transient protection, such as audio and satellite navigation systems. It is also used in the consumer electronics industry in a variety of consumer electronic products such as computers, TVs, DVD players, printers, and other related products. In addition, CPDER5V0 is frequently utilized in the industrial sector where lightning going down and high electromagnetic interference can be a problem. It is ideally suited for protecting communication and data circuits from the extreme electrical conditions.

The fundamental working principle of the CPDER5V0 is based on a Zener-breakdown mechanism. This is essentially a three-terminal diode constructed from a narrow bandgap semiconductor. When the voltage increase exceeds a certain threshold voltage, the CPDER5V0 conducts tremendous amount of current and restricts the flow of excessive electric power to safe levels. Hence, it functions by diverting the current flow away from the protected circuit.

In conclusion, CPDER5V0 is an efficient and cost-effective TVS diode that provides a compact, high-speed and low-power surge protection in various applications. The CPDER5V0 has a breakover voltage of 5V, a reverse breakover voltage of 4V, and a maximum peak pulse power rating (TPP) of 2500W at 100µs. Its Zener breakdown mechanism allows it to protect circuits from over-voltage and transients. The CPDER5V0 has a wide range of applications in the automotive, consumer electronics, and industrial sectors.
