TVS (Transient Voltage Suppressors) diodes are an important type of protection component. The SMBJ250CE3/TR13 is a popular TVS diode from Littelfuse. It is designed to protect the equipment and components it is connected to, from transients caused by surges and lightning strikes.

The SMBJ250CE3/TR13 is designed to operate over a wide range of voltages and currents, making it suitable for use in a variety of applications. It is a 250 W peak pulse power unidirectional diode, with an operating voltage range of 6.5 to 130 V and a peak pulse current of 8.9 A. It is also RoHS compliant and UL Recognized.

The SMBJ250CE3/TR13 is primarily used in applications requiring protection against high voltage transients. These include communications systems such as routers, switches, and modems, computers, automobiles, industrial automation, and aviation. The device can also be used for consumer electronics, such as CD players, DVD players, and game consoles.

The SMBJ250CE3/TR13 is an ideal choice for protecting from ESD (electrostatic discharge) and power surges. The device is designed to absorb and divert high voltage transients away from sensitive components, thus limiting damage to the equipment. The device can also clamp voltage to a specified level, ensuring that the components connected to it remain safe in the event of an overvoltage.

The working principle of the SMBJ250CE3/TR13 is based on avalanche breakdown. When an electrical current passes through the device, its internal resistance decreases. This decrease in resistance allows more current to flow, which creates a large amount of heat. This in turn causes electrons in the diode to become more energetic and release from their parent atoms. This process of electron release is known as avalanche breakdown, and it allows the voltage to be clamped at a safe level.

In summary, the SMBJ250CE3/TR13 is an ideal TVS diode for a wide range of applications. It is designed to withstand extremely high voltages and currents, and protect connected components from surges and transients. It utilizes avalanche breakdown to clamp voltage and ensure that the equipment connected remains safe in the event of overvoltage.
