TVS (Transient Voltage Suppressors) - Diodes are widely used in different applications to protect circuits from high voltage transient surges caused by an electrical or electrostatic discharge. The SMBJ10CAHE3/5B is one such TVS Diode used in various industries. This article will discuss the application field and working principle of the SMBJ10CAHE3/5B.

The SMBJ10CAHE3/5B is a unidirectional monolithic TVS Diode rated for a peak pulse power of 5 watts. It has a breakdown voltage of 10 volts, making it suitable for use in many time and cost-effective surge suppression applications. The peak pulse current at which it begins to conduct is 75 Amps, and the clamping voltage is rated at 13 volts.

Designers have to consider few things before using any TVS Diode, and the same is true for the SMBJ10CAHE3/5B. These include the surge voltage characteristics, the sharing configuration, transient response time, capacitance and dissipation characteristics.

SMBJ10CAHE3/5B is most widely used in communication system such as mobile phones, modems, routers. It is also used in power supplies, industrial controllers, and automotive systems. As for the working principle, it works by providing a low resistance path through which surge currents can flow. This prevents the circuit from being damaged due to the high voltage surge.

The SMBJ10CAHE3/5B TVS Diode is a unidirectional device that conducts current only when the applied voltage is greater than the breakdown voltage of 10 volts. When this occurs, the diode becomes an open circuit, diverting the transient surge away from the protected device. As the device slowly dissipates the energy, the voltage decreases and the diode returns to its original low resistance state.

SMBJ10CAHE3/5B also offers good capacitance characteristics as compared to other TVS Diodes. It has a low and stable capacitance of 22pf in the breakdown region. This low capacitance and wide breakdown voltage range allows it to offer superior protection against transient surges.

In summary, the SMBJ10CAHE3/5B is a unidirectional monolithic TVS Diode with a rated breakdown voltage of 10 volts, a peak pulse current of 75 Amps, and a clamping voltage of 13 volts. It is used in various communications systems, power supplies, industrial controllers, and automotive systems to protect against transient surges. It provides a low resistance path so that the energy is dissipated safely, while its low capacitance and wide breakdown voltage range makes it a superior protection device against transient surges.
