<div class="article"> <div class="title">Diodes - Rectifiers - Single</div> <h2>Applications of VS-12FLR40S05</h2> <p>The VS-12FLR40S05 is a fast-recovery rectifier, designed for various high voltage applications such as power supplies, automotive, conduit welding, switch mode power supplies, and electro-magnetic interference (EMI) filters. It is capable of operating in temperatures ranging from -55 to 175 degrees Celsius and features an ultra-fast recovery time. The VS-12FLR40S05 is available in a three-pin SOT-223 package which can easily be mounted on the board.</p> <h2>Working Principle of VS-12FLR40S05</h2> <p>The VS-12FLR40S05 functions as a rectifier, primarily responsible for converting AC or pulsating DC into a clean DC with minimal ripple. It works by allowing current to flow in one direction while blocking the flow in the opposite direction. When an alternating voltage is applied across the device, a current will flow in the anode-cathode direction once the anode voltage is higher than the cathode, thus allowing DC to pass through.</p> <p>When the voltage starts to reverse, the diode immediately blocks any current flow in the reverse direction. During this process, the diode is said to have a “recovery time”, during which it transitions from a low resistance to a high resistance state. This process makes the VS-12FLR40S05 fast-recovery rectifier ideal for high voltage applications as it guarantees low losses due to the short recovery time and low voltage peaks caused by the diode’s characteristic positive temperature coefficient which causes the conduction losses to decrease as the ambient temperature increases.</p></div>
