TVS - Diodes

VBUS054B-HSF-GS08 application field and working principle

Transient voltage suppressor (TVS) diodes are widely used in many industries. As a type of semiconductor device, they are used to protect electronic devices from excessive voltage or current, such as spikes, ESD, and other transient over voltages. The Transient Voltage Suppressor diode offers a low capacitance solution for high-speed signal lines.The VBUS054B-HSF-GS08 is a unidirectional, low-profile transient voltage suppressor diode. This TVS diode is suitable for the protection of high-speed serial data lines and network conditions where minimizing total surge clamping capacitance is necessary. The VBUS054B-HSF-GS08 TVS diode has a low capacitance of 1.2pF making it ideal for high speed applications like USB 2.0. It also has a low ≤ 1nA leakage current while capacitance is held constant. The TVS diode is available in two different packages: DFN3x3 and SOT-23.The VBUS054B-HSF-GS08 TVS diode protects against electrical transients by providing a low capacitance clamping to control voltage deviation in the supply lines. Normally, when there is an overload on the power lines, the circuit is dissipated by the TVS\' fast response time and the system is protected against the transient. TVS diodes are composed of two components; a zener diode and a protection diode. The zener diode helps to regulate the output voltage and the protection diode to prevent reverse currents. The protection diode conducts overload current, while the zener diode provides the desired clamping voltage and voltage regulator characteristics. The voltage clamping level is selected so that the maximum allowable current into the protected circuit is limited, and the voltage bypassed is low enough to prevent permanent damage.The VBUS054B-HSF-GS08 TVS diode offers superior ESD protection for pairs of data lines with matched capacitance, extremely low capacitance of 1.2pf, reverse leakage current of ≤1nA, fast response time and good surge current capability. The two package options ensure easy implementation. In summary, VBUS054B-HSF-GS08 TVS diode provides excellent protection against ESD and surge protection for serial data lines, allowing the user to easily implement higher speed serial data interfaces. It also features a low capacitance and a reverse leakage current of 1nA, making it suitable for high speed applications. Additionally, it offers fast response times and a great surge current capability. This makes this TVS diode an ideal choice for high frequency data transmission in today’s mobile and digital devices.
