VS-8TQ100SHM3 application field and working principle

Introduction

VS-8TQ100SHM3 is a single, vertical, universal plane dual Schottky rectifier ideal for cost-sensitive applications. It has a maximum reverse voltage of 100 volts and a continuous forward current of 8 amps. It is designed to provide a reliable rectangular current path, with minimal voltage drops, enabling greater efficiency during operation. This device also offers excellent static and dynamic efficiency, making it ideal for use in various power conditioning and switch mode power supply (SMPS) applications.

Application field

VS-8TQ100SHM3 is typically used in power switch-mode rectification applications, including high power factor correction, power switching and transformer rectification. It can also be used for various active box applications such as telecom power systems, network power supplies and electro-mechanical devices. It is a popular choice for its low forward voltage drop, which reduces the power losses in these system-on-chip applications.The flexibility of its power capability make it an ideal rectifier for many types of cost-sensitive applications. It has a low-power design, which makes it ideal for high-speed, low-power PCB layouts. It can also be used in a variety of simple, low-cost active box designs, where the maximum load current is approximately equal to the maximum load voltage.

Working Principle

The VS-8TQ100SHM3 rectifier is a dual Schottky rectifier made of two stacked structures. It works on the principle of pn-junction of metals, with a barrier voltage of 0.5-0.7 volts, which constitutes the low reverse current.In a rectifier device, it is important that the current flow is not affected by external factors. The rectifier works on the principle of a closed circuit, in which current is restricted to travel in a closed path. This is achieved by the use of diodes, which are forward biased, allowing current to pass through the diode and not in the reverse direction.The anode and cathode of the VS-8TQ100SHM3 rectifier are connected to the positive and negative power source respectively. During operation, when the positive voltage is applied to the anode, electrons are allowed to pass through the diode and get collected by the cathode. Consequently, current flows in a forward direction, resulting in a drop in voltage across the core.

Conclusion

VS-8TQ100SHM3 is a single, universal plan dual Schottky rectifier. It is ideal for cost-sensitive applications and offers excellent static and dynamic efficiency. It is popular for its low forward voltage drop, which reduces the power losses in board-level and system-on-chip applications. The rectifier works on the principle of pn-junction of metals, with a barrier voltage of 0.5-0.7 volts, allowing current to pass through the diode and not in the reverse direction.
