A Transient Voltage Suppressor (TVS) diode is a semiconductor device designed to protect electronic circuits from transient overvoltage events. Its primary function is to activate quickly during a voltage spike, diverting excess voltage to ground or the power line to safeguard critical components. TVS diodes are commonly used in industrial, automotive, telecommunications, and consumer electronics applications.
Key Features:
- Fast Response Time: Responds in nanoseconds to absorb surges effectively.
- High Power Handling: Capable of managing transient pulse energies up to hundreds or thousands of watts.
- Low Leakage Current: Minimal power consumption under normal operating conditions.
- High Reliability: Long lifespan design suitable for demanding environments.
Typical Applications:
- Protecting data and signal lines (e.g., USB, HDMI).
- Surge protection in industrial control systems.
- ESD protection for automotive electronics.
- Overvoltage protection in consumer electronics.
Example Specifications:
- Operating Voltage Range: 5V – 400V.
- Peak Pulse Power: 400W – 30kW (10/1000µs waveform).
- Reverse Leakage Current: <1µA (typical).
- Package Types: SMA, SMB, DO-214, DO-41, DO-15, Axial, etc.
