Application Field and Working Principle of LSM190G/TR13

The LSM190G/TR13 belongs to the category of diodes/rectifiers/single, and it is designed to perform switch-mode power supply applications. This diode has been known to deliver very high efficiency, as well as good current-handling capability. It is widely used in various type of power supplies and other DC to AC switching applications. It also has a high reverse recovery time, which makes it suitable for high speed switching.

Features

• Repetitive peak forward current of 19A
• Operating temperature range of -55°C to +175°C
• Forward voltage of 2.2V at 16A
• Low reverse leakage current of less than 0.5 µA
• High switching speed of 100ns

Working Principle

The LSM190G/TR13 can be used as a rectifier that can switch off when freewheeling current is detected. When this happens, the diode becomes non-conducting, and the freewheeling current is prevented. This process helps to reduce power loss in the circuit, as it eliminates the unnecessary power draw.

The LSM190G/TR13 also performs as a constant current source when the current limit is set. When an overload current occurs, the diode will switch into conduction and reduce the current level. This helps prevent the circuit from being damaged due to over-current conditions.

The device is also designed to have a high frequency ripple current rating. This allows the diode to withstand high frequency switching and helps to reduce noise on the load side of the circuit, as well as improve the efficiency of the overall device.

Advantages

• High current capacity of 19A
• Safe and reliable operation
• Compact size for easy installation
• High switching speed
• Low loss due to the absence of current freewheel
• Good temperature stability

Applications

The LSM190G/TR13 is commonly used in switch-mode power supplies, such as computer monitors, LCD TVs and other consumer electronic products. It is also used for LED lighting and solar photovoltaic systems. Additionally, it is commonly found in automotive, aerospace and medical applications, where high-speed, high-efficiency and precision switching are needed.

Conclusion

The LSM190G/TR13 is a high performance rectifier diode that is very efficient and reliable. It is suitable for applications that require high-speed, high-efficiency and accurate switching, such as switch-mode power supplies, automotive and aerospace electronics, medical electronics and solar photovoltaic systems.
