The BSPD300480Y3P is a type of TVS (transient voltage suppressor) designed for general purpose applications. It is a mixed technology device featuring an innovative structure that combines two different technologies: an avalanche diode to protect against high voltage surges, and a low capacitance silicon diode to protect from electrostatic discharge. The device is suitable for transient voltage protection in a variety of consumer electronics, industrial, automotive, and telecommunications applications.

Applications

The BSPD300480Y3P is designed to protect against transient over-voltages due to lightning or static discharge events. Its low capacitance structure makes it ideal for use in applications that require protection for high-speed communications interfaces, such as USB, Ethernet, HDMI, and fiber optic links. The device is suitable for consumer electronics, industrial, automotive, and telecommunications applications that require protection from voltage transients and electrostatic discharge (ESD).

Working Principle

At the heart of the BSPD300480Y3P is an innovative structure that combines two different technologies – an avalanche diode to protect against high voltage spikes, and a low capacitance silicon diode to protect from electrostatic discharge. The avalanche diode is made up of a series of PN-junction layers, which, when over-voltage is applied, act like a controlled avalanche breakdown and clamp the voltage at a predefined level. The maximum clamp voltage depends on the design and construction of the device. The low capacitance silicon diode, on the other hand, acts like a rectifier, providing protection from high speed ESD pulses.

The device is designed with high surge current capacity and ESD protection, offering reliable transient protection while maintaining signal integrity. The BSPD300480Y3P also has a low leakage current, making it suitable for use in medium voltage applications like automotive and industrial. The device also has a low thermal resistance, ensuring effective heat dissipation during operation.

Conclusion

The BSPD300480Y3P is a versatile TVS device that offers a combination of excellent ESD and high voltage surge protection. The device is suitable for a range of consumer electronics, industrial, automotive, and telecommunications applications that require high-quality transient protection. The device is designed to provide reliable protection from both high voltage and ESD pulses, while maintaining signal integrity and low thermal resistance.

In summary, the BSPD300480Y3P is an effective and reliable solution for protecting against transient over-voltages. With its innovative structure designed to combine two technologies, this device is an ideal choice for applications that require protection from voltage transients and electrostatic discharge.
