Diodes are components that have the ability to selectively let electric current flow in one direction only, making it a handy tool for conversion of alternating current to direct current. An example of such a diode is the VS-20TQ035S-M3, and the purpose of this article is to discuss details such as the application field and the working principle of this particular product.

The VS-20TQ035S-M3 is a single rectifier diode, which makes it a particularly good choice as a part of rectification circuits. Its highest working voltage is 600V, making it suitable for relatively high voltage circuits. Its average rectified current is maximumed at 20A, making it suitable for applications where a large current is needed, such as the DC motors for electric appliances.

The specific features of the VS-20TQ035S-M3, such as its leakage current being less than 0.2mA and its capacitance being less than 1pF, make it a top-notch choice as a part of high-frequency and low-noise circuits.

The working principle of a single rectifier diode can be explained as follows: The diode is arranged to let only the positive voltage pass through it. This means that the anode side of the diode will be in contact with the voltage, while the cathode will be left with a zero voltage and the circuit current will flow towards it. With the help of the built-in p-n junction, the diode will oppose the negative voltage, blocking it from passing through. The same holds true when the circuit’s polarity is reversed—the negative voltage will be blocked and the positive voltage will pass through.

Applying this mechanism for rectification circuits implies that an alternating current must be supplied to the circuit in order for the rectified voltage to be made. Connecting an AC voltage source to the diode will allow the diode to selectively pass the positive voltage, resulting in a pulsating DC voltage. In order to stabilize the DC voltage, an additional filtering circuit is usually required, depending on the application’s requirements.

The VS-20TQ035S-M3 single rectifier diode is a versatile component that can be used in a vast number of fields due to its high working voltage, high current capabilities and low leakage current. It is worth considering whenever a rectification circuit is needed, as its performance and price make it a good combination.
