Diodes are electronic components that are capable of conducting current in only one direction. They are commonly used for rectifying an alternating current (AC) signal, as well as for developing small voltage drops, which can be used as a power source. The EGL34CHE3/98 diodes are specifically designed for use in high-speed, high-frequency rectifier applications, such as the filtering and the protection circuit in switching power supplies, automotive electronics, and university laboratories. This article will discuss the application field and working principle of the EGL34CHE3/98 rectifier.

Application Field

The EGL34CHE3/98 diodes have an average forward current rating of 3A, a peak repetitive reverse voltage (VRRM) of 400V and a peak non-repetitive surge current of 25A. The package of this diode is a 4-pin DO-204AC – Axial Leaded, which ensures a reliable electrical connection in high-frequency rectifier applications. This device also features an extended thermal cycle damage resistance of up to 150 derating points. The fast switching speed of this diode makes it suitable for high-frequency circuits, as switching operation at high speeds increases the efficiency of power converters. This diode can also be used as a protection device due to its low leakage current of less than 0.2mA at its maximum reverse voltage.

Working Principle

The EGL34CHE3/98 diodes are a type of rectifier. Rectifier diodes, also known as half-wave rectifiers, consist of a P-type semiconductor material, that ‘enters’ the diode as the anode lead and an N-type side that ‘exits’ the diode as the cathode lead. When the Cathode and Anode leads are connected to a power source, the forward current traverses through the diode. When a reverse voltage is applied to the leads, the barrier potential at the junction prevents further current from oozing, effectively blocking reverse current. The fast switching speed of EGL34CHE3/98 makes it suitable for high-frequency rectifying applications. Its low leakage current also makes it an ideal protection device.

Conclusion

The EGL34CHE3/98 diodes are suitable for high-frequency, high-speed rectifier applications, as it features a fast switching speed and a low leakage current. Its extended thermal cycling damage resistance makes it an ideal device for switching power supplies, automotive electronics, and university laboratories. In summary, the EGL34CHE3/98 diodes are rectifiers that can reliably block reverse current, while allowing forward current to pass through.
