    VBUS054CD Device schematic symbol

    The integrated circuits and microchips used in the modern electronic devices are very sensitive equipment. The phenomenon of Electrostatic Discharge is very common in electronic circuits which can easily damage the ICs and microchips. ESD can be generated in a high-frequency circuit internally or externally. The electromagnetic interference and discharges are cause of great concern for sensitive electronic devices and appropriate measures must be taken for its mitigation. ESD protection devices are commonly used in electronic circuits for ESD protection.

    What is VBUS054CD-FHI-GS08?

    The VBUS054CD-FHI is a four line ESD protection device manufactured by Vishay Semiconductors. The device has characteristics similar to a Z-diode with high ESD immunity and very low capacitance. These features make the VBUS054CD-FHI suitable for high frequency applications such as USB 2.0 and HDMI. The VBUS054CD-FHI provides active protection against transient voltages and ESDs for up to four high speed data lines. The device will clamp the negative transients close to ground level and positive transients close to 5V level. Due to its bi-directional and asymmetrical operation, the VBUS054CD-FHI is suitable for electronic circuits operating on 5VDC or below.

    How VBUS054CD-FHI-GS08 work?

    The modern computer systems, audio/video systems and communication systems employ high frequency digital circuits for fast data processing. These high speed digital systems offer a lot of performance related benefits however their biggest drawback is the low immunity towards electrostatic discharges and electrostatic interference. These ESD and EMI signals can easily damage the sensitive digital electronic chips and circuits. The high speed digital systems such as USB 2.0 (480 Mbps) and HDMI (1.65 Gbps) operate on very high frequencies and are prone to ESD damages. To counter the negative effects of ESD in such circuits, ESD protection devices are employed. The VBUS054CD-FHI is a special purpose ESD protection device which is specially designed for high frequency digital systems and provides ample protection against the ill effects of ESD.
