VESD03A1B-HD1-GS08 Circuit Protection

TVS diodes are essential components of electronic devices and circuits. They protect sensitive circuits from voltage spikes that could otherwise cause component damage or complete system failure. The VESD03A1B-HD1-GS08 from Vishay Semiconductors is part of their ESD Suppression Diode family and provides reliable protection for a range of electronics products.

The VESD03A1B-HD1-GS08 is a small surface-mount diode with a low profile case size of 0303. It is an optimized ESD protection diode for USB ports, and is designed for fast transient response and superior clamping characteristics while providing low capacitance. The diode is available in SOD-323 packaging, making it ideal for high density PCBs with limited space.

The VESD03A1B-HD1-GS08 is designed for use in USB Type C ports that deliver up to 20V and 3A. It provides excellent protection against electrostatic discharge (ESD) up to ±8kV contact discharge according to IEC 6100-4-2 specification. The TVS diode has a peak pulse power rating of 140W (100μs tp=8/20μs waveform).

The VESD03A1B-HD1-GS08 has a working principle that helps it protect sensitive electronics against voltage spikes. The diode acts as a bidirectional switch when an overvoltage situation occurs. When the voltage rises, the diode will begin to conduct and create a short circuit, which dissipates the charge in a controlled manner and prevents it from reaching the vulnerable components. Once the surge has passed, the diode will return to its previous state and the circuit will continue to function as normal.

The VESD03A1B-HD1-GS08 is designed for a wide range of applications. It is used in USB Type C ports, as well as in power or data ports that require fast rise times and superior clamping performance. It is also suitable for any ESD protection applications, such as automotive, industrial, medical and consumer electronics, where ESD protection is necessary.

In summary, the VESD03A1B-HD1-GS08 is a compact and reliable ESD protection diode from Vishay Semiconductors. It is designed for fast transient response and superior clamping in a wide range of applications including USB Type C ports, power or data ports, and automotive, industrial, medical and consumer electronics. The diode works by providing a short circuit when an overvoltage situation occurs, dissipating the charge in a controlled manner and preventing it from reaching the vulnerable components.
