It is also used in the manufacturing of ideal diode circuits, power equipment production, neutral position detection, and safety circuits in the motor industry.

The JANS1N6642US rectifier diode has an extremely fast switching time, allowing for higher efficiency in its fast recovery time (tRR). It has a relatively low forward voltage drop of 0.51 V at 15 A which further enhances its efficiency. The device also has a high forward surge current rating (I FSM ) allowing it to work in power applicator and DC brushless motor applications. The device also has a thermal resistance junction to case of 0.30°C/W, ensuring that it can dissipate heat effectively.

Working Principle

The JANS1N6642US rectifier diode works on the principle of the diode idealism current flow. It is a voltage operated device with a forward junction voltage which acts as a barrier against the flow of current in the reverse direction. Electrical energy is converted into electrostatic energy, which when linked to the anode flows in the form of electric current in the forward direction. When the forward biasing voltage is greater than the reverse biasing voltage the electric current flows in the forward direction.

In the case of the JANS1N6642US, the maximumaverage current rating of the device is 6.4A, implying that a maximum of 6.4A will be able to flow in the forward direction at any particular voltage, no more than that. As the device can take maximum current of up to 3300V, it can be used in various applications.

Conclusion

The JANS1N6642US fast recovery rectifier diode is a highly efficient and versatile single phase, three phase and full wave rectifier with features like fast switching and low forward voltage drop ensures that it is a very effective device that can be used in a variety of applications. With its wide range of operational characteristics, the JANS1N6642US is a suitable choice for applications that require rectification of AC power sources.
