Introduction

FESF16CTHE3/45 is a single rectifier diode with a voltage rating of 45V and a current rating of 16A. It is part of a series of fast recovery rectifier diodes, designed to reduce EMI (electromagnetic interference) from high frequency switching circuits. The FESF16CTHE3/45 has fast switch-on and switch-off time, low distortion, low capacitance and low forward voltage drop, and is suitable for use in high frequency, switch-mode power supplies, and other power electronic circuits.

Application Field

The FESF16CTHE3/45 rectifier diode is used in a range of power supplies and power electronic circuits. These include DC to AC conversion, DC to DC conversion, AC power supplies, solar power converters, uninterruptible power supplies, switched-mode power supplies, motor drives, servo drives, brushed and brushless motor controllers, DC motor controllers and other circuits that require fast switching at high frequency.

Working Principle

The FESF16CTHE3/45 rectifier diode works on the principle of rectification. Rectification is the process of converting alternating current (AC) electricity into direct current (DC) electricity using a diode, which acts as a one-way switch, allowing current to flow in one direction only. This diode is designed to operate at high frequency, up to 3-4 kHz, due to the fast recovery time of the semiconductor material used in its construction.When the AC voltage is applied to the diode, the anode will be positive and the cathode will be negative. This creates a small potential difference across the diode, known as the forward-bias potential. The diode then allows current to flow in one direction, from anode to cathode, while blocking current from flowing in the opposite direction. This type of rectification is known as rectification by pulsing, and it allows the resultant DC voltage to be switched on and off quickly, making it suitable for use in high frequency switching circuits.

Conclusion

The FESF16CTHE3/45 rectifier diode is a high performance single rectifier diode, designed for use in a range of power supplies and power electronic circuits. It has fast switch-on and switch-off time, low distortion, and low forward voltage drop, making it ideal for applications that require fast switching at high frequency. Its fast recovery time also makes it suitable for use in circuits where EMI (electromagnetic interference) must be reduced.
