STMicroelectronics SM6T39A Transil™ Transient Voltage Suppressor

The SM6T39A from STMicroelectronics is a robust Transil™ transient voltage suppressor (TVS) designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This high-performance device is specifically engineered to safeguard voltage-sensitive components which can be affected by these sudden and extreme voltage variations.

With its standoff voltage of 33.3V and a maximum clamping voltage of 53.9V at 10/1000 µs, the SM6T39A ensures that any transient over this threshold is effectively clamped, providing a safeguard for your circuitry. The device is capable of handling a peak pulse power of 600W (10/1000 µs), making it an excellent choice for absorbing high energy transients that could potentially cause irreversible damage to electronic components.

The bidirectional nature of the SM6T39A means that it can provide protection in both directions, making it versatile for use in AC applications or where the polarity of the transient may be uncertain. This feature simplifies circuit design and reduces inventory, as you only need one part number to provide protection in both directions.

Constructed in a DO-214AA (SMB) package, the SM6T39A is designed for easy implementation into a wide variety of applications. Its compact form factor makes it suitable for high-density circuit boards where space is at a premium. Additionally, the package is compliant with both RoHS and Halogen-Free requirements, ensuring that it meets the latest environmental standards for electronic components.

Applications for the SM6T39A include protection for sensitive electronics in telecommunications systems, computer interfaces, and other industrial and consumer electronic devices that are prone to transient events. Its fast response time and high surge capability make it an ideal choice for protecting power busses and I/O interfaces in these types of applications.

Overall, the SM6T39A from STMicroelectronics represents a reliable and efficient solution for transient voltage suppression. Its robust design and versatile protection capabilities make it a critical component for enhancing the durability and reliability of electronic systems.
