The SMDB3 from STMicroelectronics is a state-of-the-art bidirectional Transient Voltage Suppression (TVS) diode designed to protect voltage-sensitive components from destructive voltage spikes and transient events. Its bidirectional nature ensures protection in both directions, making it ideal for AC applications or where the polarity reverses.

Key Features

• Breakdown Voltage: The SMDB3 offers a precise breakdown voltage range, ensuring reliable protection against overvoltage events.
• Peak Pulse Power: With its ability to handle 200W peak pulse power (8/20μs waveform), the device can absorb high transient energies without damage.
• Low Leakage Current: The diode is engineered to have a very low leakage current, enhancing system reliability and reducing power loss.
• Fast Response Time: The SMDB3 reacts quickly to transient events, ensuring immediate protection for sensitive circuits.
• Package: Housed in a small SMB (DO-214AA) package, this component is suitable for compact designs and offers good thermal dissipation characteristics.

Applications

The versatile nature of the SMDB3 makes it suitable for a variety of applications, including:

• AC/DC power lines
• Telecommunication systems
• Computer interfaces
