Transient voltage suppressors (TVS) diodes are designed to provide protection for all kinds of circuits against high voltage transients. The SMBJ28CHE3/52 is a bi-directional TVS diode with excellent surge handling capabilities in a robustly designed package. Its PN junction structure and SMB case make it an excellent choice for applications requiring transient protection and outstanding EMI/EMC performance.

The SMBJ28CHE3/52 is designed to protect data and signal lines in electronic equipment against overvoltage transients due to inductive loads, such as from electrostatic discharge (ESD) or electrical fast transient (EFT). It is most commonly used in automotive, automation, industrial and consumer applications. It works in both polarities and can be used to protect circuits from voltages up to 28V.

In terms of functionality, the SMBJ28CHE3/52 offers a wide range of protection features, including: thermal protection, ESD protection, EFT/burst protection, load dump protection, and overcurrent protection. Thanks to its excellent thermal and mechanical properties, the SMBJ28CHE3/52 is an ideal solution for transient protection in all kinds of applications. Its low capacitance and high transient overload capability make it an effective solution for protecting delicate electronics against voltage transients.

The TVS diode works by diverting the surge current to the ground, thus limiting the voltage across the protected load. The diode is designed to switch quickly when the incoming voltage is too high, allowing it to protect the load from damaging voltages that could occur in the absence of a TVS diode. When the voltage returns to a safe level, the diode will switch off and return to its basic state.

The SMBJ28CHE3/52 has a number of features that make it an ideal choice for transient protection. Its high peak pulse power capability and low reverse-leakage current reduce power loss, while its low inductance minimizes distortion in high frequency circuits. The SMBJ28CHE3/52 is also a self-regulating device, meaning that its performance is not affected by temperature or voltage variations.

The SMBJ28CHE3/52 is RoHS-compliant and offers effective EMI/EMC performance, so it can be used in a variety of high-frequency applications. It also has a maximum working temperature of 175°C, ensuring its optimum performance even in high temperature environments. Its wide range of features and versatility make the SMBJ28CHE3/52 an excellent choice for transient protection applications.
