TVS Diodes are transient voltage suppressors, or sometimes referred to as transient voltage surge suppressors, which are used to protect sensitive electronic devices such as microprocessors, from surges, high voltage, and electrostatic discharges. The SMCJ28HE3/57T is a Unidirectional TVS Diode, which is widely used in circuits that require over-voltage protection from up to 28V of a 57A surge. This diode is particularly useful for AC applications because it can protect circuits from high-voltage shocks.

The SMCJ28HE3/57T diode has many application fields, such as mobile phones, tablets, consumer appliances, computers, industrial equipment, and automotive electronics applications. In particular, this diode is used for Non-Earth DC grounding applications due to its low reference lead capacitance. Additionally, in cases where multiple TVS diodes are required in the same circuit, this diode can also be used due to its low volume and high surge capability.

The working principle of the SMCJ28HE3/57T diode is simple and based on the flow of the current through the diode. When the normal operating voltage is applied to the diode, it will remain in the off-state and will not allow the current to flow. However, when a surge of voltage is applied to the diode, it will turn on and start to conduct the current until the surge is gone. This will prevent any further over-voltage from going into the circuit and therefore protecting the components from damage.

The SMCJ28HE3/57T diode offers a great deal of protection to the circuit from surges and high voltage shocks. It is able to provide up to 57A of surge current and is perfect for AC applications that require voltage protection. Additionally, it is also ideal for multiple TVS diode applications, due to its low volume and high surge capability. All of these features combine to make this diode a great choice for many different applications.
