STMicroelectronics SMBJ28A-TR TVS Diode

The SMBJ28A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes and transients induced by lightning and other transient voltage events. It is a part of ST's SMBJ series, which are known for their reliability and performance in surge protection applications.

This TVS diode is capable of clamping and dissipating high transient overvoltages, thus safeguarding the components in electronic circuits. With its stand-off voltage of 28V, it ensures that voltage levels remain within safe limits for a variety of components. The SMBJ28A-TR is particularly suited for applications where a precise triggering voltage level is crucial for system safety and reliability.

Encased in a DO-214AA (SMB) package, the SMBJ28A-TR is compact and easy to integrate into a wide range of electronic devices. Its small footprint makes it an ideal choice for space-constrained applications, while still providing high surge capability. The device features a peak pulse power dissipation of 600W (10/1000μs waveform), allowing it to handle significant power surges without damage.

Furthermore, the SMBJ28A-TR is characterized by its fast response time to transient events, typically in the picosecond range, which ensures that it reacts almost instantaneously to overvoltage conditions. This is critical for protecting sensitive circuit components that can be damaged by brief voltage spikes.

Designed to meet IEC standards, the SMBJ28A-TR is compliant with IEC 61000-4-2 for electrostatic discharge (ESD), IEC 61000-4-4 for electrical fast transients (EFT), and IEC 61000-4-5 for surge immunity. This compliance ensures that the device can be used in applications that require adherence to strict regulatory standards.

In summary, the STMicroelectronics SMBJ28A-TR TVS diode is a trustworthy and efficient solution for protecting electronic equipment from voltage transients. Its combination of high surge capacity, fast response time, and compliance with international standards makes it an excellent choice for safeguarding a wide array of electronic applications.
