The 1SMB28AT3 by ON Semiconductor is a robust surface-mount Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This high-performance device is a preferred choice for a wide range of applications, including but not limited to industrial, computing, automotive, and consumer electronics, where reliability and durability are of paramount importance.

Constructed with ON Semiconductor's cutting-edge technology, the 1SMB28AT3 offers a peak pulse power dissipation of 600 Watts (@10/1000μs waveform), which ensures that devices are shielded from sudden surges of power. Its stand-off voltage is 28V, which is the maximum voltage that can be applied over the diode without causing it to conduct in avalanche breakdown, providing a margin of safety for electrical circuits.

The device's fast response time is remarkable, reacting to over-voltage events in picoseconds, thereby offering instantaneous protection for circuit components. Furthermore, its low incremental surge resistance and excellent clamping capability ensure that the voltage spike is effectively managed, minimizing the risk of damage to the protected component.

The 1SMB28AT3 comes in a compact SMB package, which not only saves valuable board space but also offers ease of integration into a variety of circuit designs. It meets the ISO 7637-2 and ISO 16750-2 standards for load dump, thus making it a reliable choice for automotive applications. Additionally, it is compliant with the IEC 61000-4-2 and IEC 61000-4-4 environmental and immunity standards, ensuring that it can withstand harsh operating conditions.

ON Semiconductor's commitment to quality is evident in the 1SMB28AT3, which is characterized by its high reliability and consistent performance. It is RoHS compliant, meaning it meets the European Union's restrictions on the use of certain hazardous substances in electrical and electronic equipment. With the 1SMB28AT3, designers and engineers can confidently protect their electronic systems, ensuring longevity and stability in their products.
