SS3P6HM3/84A application field and working principle

SS3P6HM3/84A is a fast recovery single-phase rectifier diode for general-purpose applications. This diode features low internal loss, fast switching speed, high thermal cycling capability and high junction temperature. It is widely used in induction heating, frequency output, motor drive, fast recovery and other occasions.

A rectifier diode is a crystal semiconductor with a PN junction, which is equivalent to two diodes connected in series back to back. It has the functions of conversion and rectification, also known as a full-wave rectifier diode. When connected in the rectifier circuit, it can achieve bidirectional conduction and realize the function of conversion and rectification.

Application fields

SS3P6HM3/84A fast recovery single-phase rectifier diode have good performance and are widely used in frequency output, induction heating and motor control, fast power supply and other occasions. In the driving circuit of the energy-saving lamp, it can be used as a current limiting protection and over-strength protection, as well as for frequency output, power electronics, current rectification, induction heating and motor control.

Working principle

When the diode is connected in the direct current circuit, the diode is turned on or off according to the potential difference between the two ends of the diode, allowing current to flow only in one direction, that is, allowing only unidirectional current, but not allowing current to flow in the opposite direction. This is because the diode acts like a one-way valve gate. When the diode is connected in the alternating current circuit, the diode conducts and blocks in time sequence. This is because the waveform of alternating current can be divided into two square waveforms of opposite polarity: when the voltage waveform moves positively, the anode end is higher than the cathode end, and the diode is turned on, allowing current to flow through the circuit. When the waveform moves negatively, the anode end is lower than the cathode end, and the diode turns off, blocking current.

Conclusion

SS3P6HM3/84A is a fast recovery single-phase rectifier diode, with low internal loss, fast switching speed, high thermal cycling capability and high junction temperature. It is widely used in induction heating, frequency output, motor drive, fast power supply and other occasions, and has the functions of conversion and rectification. The working principle is that the diode is like a one-way valve gate that can conduct and block in time sequence when connected in the alternating current circuit.
