TVS (Transient Voltage Suppressor) devices are designed primarily for use in circuit protection applications. Varistors, MOVs (Metal Oxide Varistors), and V39ZT1PX2855 devices are popularly used as TVS devices in automotive, communication, and consumer electronic designs. This article will discuss the application fields and working principles of V39ZT1PX2855.

Application Fields

V39ZT1PX2855 is a high-energy, bi-directional TVS diode which provides cost-effective protection to equipment from transients across multiple wires. The device is designed for isolating serial or parallel data lines and serial or parallel signal lines from high-energy pulses, both on the PCB (Printed Circuit Board) level and in systems. It can also provide protection against damage from external voltage sources. V39ZT1PX2855 is ideal for protecting high-speed I/Os (Input/Outputs), point-of-load converters, power supplies, and critical control circuits in automotive, consumer electronic, communication, computer, telecom, and power-control applications.

Working Principle

V39ZT1PX2855 is a bi-directional TVS device with both low-clamping, reverse-blocking voltage rating and high-clamping, forward-blocking voltage rating. The device will clamp or repel excessive voltage depending on the direction of the voltage and the voltage level. When an excessive voltage of either polarity is applied to the device, it will enter into its conduction state. When the excessive voltage is removed, the device will go back to its non-conductive state.

The device has a high clamping voltage which assures a very low clamping voltage drop during its conduction, and thereby provides a low stress to the protected components. The ESD (Electro Static Discharge) protection capability is superior to other devices. The device can effectively clamp transient voltages and dissipate high energy pulse in a fraction of a second. The high surge capability and low leakage current make it ideal for use in high frequency and high efficiency power converter applications.

Conclusion

V39ZT1PX2855 is an advanced and cost-effective TVS diode which is designed for protecting circuit components from transients and voltage source from damage. Its high clamping voltage and low clamping voltage drop protect the circuit components against high energy pulses while maintaining a low stress level. The device is ideal for applications in automotive, consumer electronic, communication, computer, telecom, and power control fields.
