SM5S33HE3/2D

SM5S33HE3/2D is a type of overvoltage protection device which falls under the umbrella of Transient Voltage Suppressor (TVS) Diodes. These diodes are specifically designed to clamp and regulate the voltage across an electronic system, protecting it from the damaging effects of overvoltage, undervoltage, and Electro-Static Discharge (ESD).

The SM5S33HE3/2D is engineered for precision performance in overvoltage protection applications. It operates in accordance with a Modified Voltage Controlled Avalanche breakdown to protect high-speed data lines. This device has an operating voltage range of 5V - 33V and a peak pulse power rating of 650W at 10/1000μs.

The SM5S33HE3/2D has no insertion loss or ringing, making it suitable for high-speed applications. Additionally, it allows for bidirectional current flow and offers excellent EMC compliance while featuring the small size (6.0x5.2x1.5mm).

The working principle of the SM5S33HE3/2D is based on avalanche breakdown of lightly doped semiconductor junctions, which forms a low impedance arc that clamps the voltage and conducts reverse current. This prevents the main system’s power rail voltage from exceeding a certain threshold. The device also has an excellent EMC performance, ensuring that any radiated noise or interference is suppressed.

The SM5S33HE3/2D is widely used in consumer electronics, automotive, medical, and communication systems, to prevent electronic components from damage caused by Voltage, ESD, and other anomalies. It is also widely used in applications such as protection against voltage overshoot transients, protection in systems with limited protection circuits, and protection against mass transit ESD.

Overall, the SM5S33HE3/2D TVS-diode is an ideal device for preventing electronic components from damage caused by overvoltage and ESD. Its low leakage current and fast response speed make it perfect for system protection in a wide range of applications.
