Diodes - Rectifiers - Single

SE10PD-E3/85A is a single-phase, ultrafast, soft-recovery rectifier diode, often used in UPS, Power Converters, Motor Controls, and Arc Welders.The SE10PD-E3/85A diode utilizes a patented active internal protection circuit that keeps the device from drifting out of its specifications, which helps ensure the reliability of the device. This circuit also greatly reduces the levels of damaging reverse voltage leakage current, as well as ESD protection up to 8KV.Here is an overview of the SE10PD-E3/85A’s application field and working principle.

Application Field

The SE10PD-E3/85A is used in many power control devices, such as uninterruptible power supplies (UPS) and power converters. With its active internal protection circuit, the SE10PD-E3/85A is a solid choice for reliability and accuracy. In motor control applications, the SE10PD-E3/85A diode is ideal. Its soft-recovery characteristic means that the surge currents that occur during switching cycles are minimized, allowing for lower thermal stress, reduced switching losses, and extended operating life of the device.It is also suitable for welding applications, and is often combined with other power components, such as inverters and thyristors, to create an optimal, efficient arc welding machine.

Working Principle

The SE10PD-E3/85A is a single-phase, ultrafast, soft-recovery rectifier diode that functions by allowing electrons to move freely in one direction and not in the opposite direction. This single-directional movement enables the device to cause a current to flow in the form of an electric charge, which then moves along the wires, creating a type of “charge pump effect”. In power applications, the charge pump effect of the SE10PD-E3/85A creates a continuous voltage in one direction, as opposed to the pulsing off and on pattern that is seen in traditional power supplies. This helps to reduce the heat generated by the device and increase the efficiency of the power conversion process. The active internal protection circuit of the SE10PD-E3/85A also monitors the temperature of the semiconductor material while in use, and if it exceeds a predetermined threshold, the device will enter a self-protect mode and begin to turn off. This prevents the device from progressing to a condition where it can be damaged due to excessive heat.The SE10PD-E3/85A also supports ESD protection up to 8KV, which helps to prevent damage to components due to static electricity.

Conclusion

The SE10PD-E3/85A is an ultrafast, soft-recovery rectifier diode that is well-suited for a wide variety of power control applications. Its active internal protection circuit helps to ensure the accuracy and reliability of the device, and its ESD protection up to 8KV helps to protect components from potentially damaging static electricity. With its wide range of features, the SE10PD-E3/85A is a reliable and efficient choice for many power control applications.
