The SMA6T28AY is a state-of-the-art Transil™ transient voltage suppression (TVS) diode, designed by STMicroelectronics to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. This robust component is specifically engineered to safeguard voltage-sensitive devices against high energy transients and surges that can occur in harsh environments.

The SMA6T28AY is housed in a compact DO-214AC (SMA) package, which not only saves valuable board space but also ensures a low profile in the overall design. It features a stand-off voltage of 28V, making it suitable for a wide range of applications, including industrial, automotive, computer, and telecom systems where reliability and performance are critical.

With a peak pulse power dissipation of 600W (10/1000μs), the SMA6T28AY provides excellent clamping capability, ensuring that devices remain protected even under the most demanding transient conditions. Its fast response time is crucial for modern circuits where quick protection is essential to prevent immediate damage to semiconductors and other sensitive components.

STMicroelectronics has designed the SMA6T28AY with a low leakage current, which is beneficial for energy-saving applications and contributes to the overall efficiency of the system. Its low incremental surge resistance helps to minimize the voltage drop during a surge event, ensuring the protected device is exposed to a voltage within its tolerance limits.

The device is compliant with the IEC 61000-4-2 and IEC 61000-4-5 standards, offering guaranteed performance in electromagnetic compatibility (EMC) tests. Furthermore, the SMA6T28AY is RoHS compliant and halogen-free, making it an environmentally friendly choice for manufacturers looking to create green products.

In summary, the SMA6T28AY from STMicroelectronics is an excellent choice for designers who need a reliable, high-performance TVS diode that can withstand severe voltage transients while maintaining a low profile and energy efficiency in their electronic designs.
