ES1DHE3_A/H Application Field and Working Principle

ES1DHE3_A/H is a single rectifier diode designed for a variety of high-power applications. This device is a special Schottky barrier diode, also known as a "hot-carrier diode" or Schottky diode. The Schottky diode enjoys a low voltage drop when compared to existing diode technology, making it an ideal choice for applications that must minimize losses.

ES1DHE3_A/H is a "fast-recovery" diode, which means that it can switch quickly, with minimum switching losses. This makes it suitable for high frequency applications, such as switching power supplies, frequency converters and switched-mode power supplies. It is also highly suitable for rectification purposes, particularly when very high peak or reverse surge currents are required. The device offers very good reverse recovery characteristics, giving it good performance in this area.

ES1DHE3_A/H is available in a variety of packages, with either a through-hole or a surface-mount version. Its operating temperature range is from -55°C to +125°C, making it suitable for most commercial and industrial applications.

Working Principle

The diode is a two-terminal device that carries current only in one direction. When forward biased with a voltage above a certain threshold value, known as the cut-in voltage or forward turn-on voltage, a conducting path is created between the anode and cathode. This conducting path is known as the depletion region and it is this region that allows current to flow.

When the forward bias is reversed, the depletion region increases in size and current flow is rapidly reduced, due to the reverse junction capacitance. This capacitance is extremely important, as it is this capacitance that allows the device to switch quickly. Reverse current begins to flow, and as the reverse voltage reaches a certain level, a certain percentage of the reverse current no longer flows across the junction but is diverted inwards and stored.

This stored current must be discharged in order to turn the device back on again, and the rate at which this charge is discharged is known as the rate of recovery or reverse recovery time. The faster the rate of recovery, the more efficient the diode is. The ES1DHE3_A/H diode offers excellent reverse recovery times, making it highly efficient and suitable for high frequency applications.
