Surge-protection diodes, also known as transient voltage suppressors (TVS), are commonly used in integrated circuits that have to be protected from voltage fluctuations. The SMCJ28C is a type of unidirectional TVS diode used in applications such as USB ports, Ethernet ports, power supplies, and I/O ports. The SMCJ28C is designed to protect delicate components from damage caused by electrostatic discharge, transients, and overvoltages.

When an overvoltage occurs, the SMCJ28C will conduct current and divert the extra voltage away from the sensitive components. It acts as a “fuse” that will be destroyed if the overvoltage is too high. This prevents further damage to the circuit. The SMCJ28C is capable of handling up to 28V of peak pulse current, and is designed to be used in temperatures ranging from -65°C to 150°C.

The SMCJ28C is constructed with a glass passivated junction, which provides reverse voltage protection up to 28V. The diode is housed in a SMC package, which is designed to dissipate heat quickly, preventing thermal runaway and making sure the components have a long service life. The package also has a low profile, making it easier to fit in tight spaces.

The design of the SMCJ28C allows it to respond quickly to transients. As soon as the voltage falls back within the safe limits, the diode will automatically turn back off. This prevents potential damage to the circuit. The SMCJ28C is designed to withstand higher power surges and withstand voltages up to 150V. It can also handle both ESD and overvoltage transients, making it a great choice for many electronic systems.

In addition to protecting against overvoltages, the SMCJ28C can also be used as a safety feature to prevent reverse current. If the voltage applied to the circuit is reversed, the diode will become active and prevent current from flowing in the wrong direction. This is an important safety feature that helps protect the circuit from damage due to potential electrical hazards.

The SMCJ28C is a reliable TVS diode that can be used in many electronics applications. Its rapid response to transients, high power handling capabilities, and reverse current protection make it a great choice for protecting delicate electronics. Whether it’s used in a USB port, power supply, Ethernet port, or any other application, the SMCJ28C will be up to the task.
