Introduction

A TVS diode, or transient voltage suppressor, is a semiconductor device designed to protect electrical components from voltage spikes, surge currents, and dangerously high voltages. The 1N6289A-E3/73, an unidirectional TVS diode, is designed to protect components and circuit boards from unwanted electrical transients.

Application Field

The 1N6289A-E3/73 is a bidirectional, unidirectional TVS diode designed specifically for power systems applications. It can be used to protect sensitive components like communication microprocessors, data converters, precision-control circuits, and DRAMs from transient over-voltages and surge currents. It is also well-suited to provide surge protection to the I/O ports of PCs, laptops, and other electronic consumer products. It is well-suited for use in high-reliability applications such as automotive, industrial, and telecommunications equipment.

Working Principle

The 1N6289A-E3/73 is a Zener-like TVS diode designed to provide protection from over-voltage transients. It consists of a semi-conductor body whose threshold voltage defines the clamping voltage of the diode. When the applied voltage exceeds the threshold, the diode conducts current, clamping the voltage and protecting the components connected to it. The 1N6289A-E3/73 has a nominal reverse breakdown voltage of 72V and a maximum peak pulse current of 32A. It has a low 5 pF capacitance, which allows it to respond quickly to transients. It has very low leakage current, making it well suited for use with sensitive circuits. The 1N6289A-E3/73 is built in a RoHS-compliant SMT package, allowing for easy installation on circuits.

Advantages

The 1N6289A-E3/73 offers several advantages over other TVS diodes, including: i. Low capacitance, allowing for a fast recovery time.ii. Low leakage current, making it suitable for use with sensitive circuits. iii. Low on-state voltage, allowing for increased system efficiency. iv. RoHS-compliant SMT package, making it easy to install. v. High peak pulse rating.

Conclusion

The 1N6289A-E3/73 is a unidirectional TVS diode designed for power systems applications. It provides protection from over-voltage transients and surge currents. It has a low capacitance, allowing for fast recovery time, and a low on-state voltage, increasing system efficiency. Its RoHS-compliant SMT package allows for easy installation, while its peak pulse rating makes it suitable for high-reliability applications.
