STMicroelectronics SMBJ58A-TR TVS Diode

The SMBJ58A-TR from STMicroelectronics is a state-of-the-art transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This robust component is an ideal solution for safeguarding voltage-sensitive components which can be affected by these high energy phenomena.

Encased in a compact SMB (DO-214AA) package, the SMBJ58A-TR is engineered to deliver high surge capability, with a stand-off voltage of 58V. It can handle pulses in accordance with the industry-standard test waveform of 10/1000μs. Its peak pulse power dissipation is an impressive 600W (10/1000μs), providing a reliable shield against transient threats. The device is optimized for a broad range of applications, including but not limited to consumer electronics, computer systems, industrial equipment, and telecommunication systems.

This TVS diode features a unidirectional configuration, which means it offers protection in one direction, making it suitable for DC voltage applications. Its fast response time is less than 1 picosecond from 0V to BV min, ensuring quick and effective protection. The SMBJ58A-TR also has a low incremental surge resistance and is RoHS compliant, adhering to current environmental standards for hazardous substances.

The SMBJ58A-TR is characterized by its excellent clamping capability, which ensures that the voltage presented to the protected component does not exceed the maximum allowable voltage for that component. This is critical in preventing damage and extending the life of the electronic device. Additionally, its low leakage current minimizes power loss and ensures that the diode does not affect the normal operation of the circuit when no surge is present.

Overall, the SMBJ58A-TR from STMicroelectronics is a reliable and efficient solution for circuit protection in a variety of applications. Its robust design, combined with high surge capability and fast response time, makes it a preferred choice for engineers looking to enhance the durability and longevity of their electronic products.
