ES1JHM2G Application Field and Working Principle

ES1JHM2G is a silicon epitaxial planar type of rectifier diode designed for use in high frequency rectification and switching applications. This product has the maximum repetitive reverse voltage of 1000V and the maximum average forward current of 1A. It is designed for operation in high frequency circuit applications using the junction capacitance to determine the operating frequency.

Application Field

• Switching applications
• High frequency rectification
• High frequency switching electronics
• High frequency power supplies

Working Principle

The ES1JHM2G is operated in a reverse bias mode to provide rectification. In a reverse-biased diode, the diode acts as a perfect insulator. The resistance across the diode is higher than the resistance in forward bias and so no current passes through the diode. This is how the rectification of AC voltage occurs. The diode acts as a one-way street and allows current to pass in one direction only.

The forward conductivity of the ES1JHM2G is determined by the N-type and P-type silicon that makes up the junction layer of the diode. Electrons from the N-type material move to the P-type material, leaving the P-type material with a surplus of electrons, creating a low-resistance path for the current to flow in the forward direction.

The rate of conduction of electrons through the diode depends on the type of junction and the amount of forward bias applied has. This amount of forward bias is determined by the applied voltage to the diode and the dynamic resistance. The higher the forward bias, the higher the current that passes through the diode. The forward bias voltage is also important in determining the switching frequency of the device.

The junction capacitance of the diode plays an important role in determining the switching frequency of the device. It is the capacitance of the junction that determines the maximum frequency at which the device can switch. The junction capacitance is also known as the Miller capacitance as it is proportional to the gate voltage of the diode.

The junction capacitance decreases as the forward bias increases and so the frequency of the device decreases as the forward bias increases. This is why the forward bias voltage is important in controlling the switching frequency of the device.

The ES1JHM2G is a reliable and efficient device suitable for a wide range of applications in the field of electronics. It is a versatile device due to its high frequency switching capabilities and its ability to operate in both forward and reverse bias mode.

The ES1JHM2G is an invaluable tool in the design of power electronics systems and can be used to build reliable and efficient power supplies, converters and switch modes.
