CMDSH2-3 TR Application Field and Working Principle

The CMDSH2-3 TR is a single rectifier diode, providing an ideal power platform for AC-DC applications and power factor correction (PFC). Among other uses, it can be used in a variety of switching power electronics applications such as AC-DC buck converters, AC-DC fly-back converters, zero voltage switches (ZVS) and LLC resonant converters.

Application Field

The CMDSH2-3 TR is suitable for a wide range of power supplies such as telecom power supplies and solar inverters. It also finds application in LED lighting, automatic voltage regulators, and industrial automation.

Working Principle

A rectifier diode is a two-terminal semiconductor device that acts as an electrical switch, allowing current to flow in only one direction. The CMDSH2-3 TR is a single-phase, ultra-high voltage (UHV) rectifier diode that offers very low losses due to its low forward voltage drop. This makes it suitable for high-efficiency DC-DC converters, eliminating the need for a heat sink.

The diode has an avalanche rating of 650V, making it suitable for high-voltage applications. The soft recovery characteristic helps reduce switching losses, while the low forward voltage drop minimizes conduction losses. The CMDSH2-3 TR also has an ultra-fast reverse recovery time, which helps improve transient response time and reduce EMI.

Conclusion

The CMDSH2-3 TR is an ultra-high voltage rectifier diode that offers very low losses and superior performance. It is suitable for a wide variety of power supplies, including telecom power supplies, solar inverters, LED lighting, automatic voltage regulators, and industrial automation. It has a low forward voltage drop, an avalanche rating of 650V, a soft recovery characteristic, and an ultra-fast reverse recovery time.
