Diodes - Rectifiers - Single

The LSM190GE3/TR13 is a single-phase, glass-passivated, ultrafast, high-efficiency rectifier diode. It is suitable for use in a wide variety of rectification circuits, including AC to DC rectification and Power Factor Correction (PFC) applications. The device has a high Blocking Voltage of up to 1.0kV, making it ideal for higher-voltage applications.

Application Field

The LSM190GE3/TR13 rectifier diode can be used in a variety of rectification applications, including AC to DC rectification and PFC. The device’s high Blocking Voltage of up to 1.0kV makes it suitable for higher-voltage applications, such as PC power supplies, automotive electronic systems, and battery charging. It can also be used for high-frequency rectification, such as noise suppression, line filtering, and DC/DC power converters.

Working Principle

The working principle of the LSM190GE3/TR13 rectifier diode is based on the fact that when a voltage is applied to the device, only one type of current can flow. For example, when a positive voltage is applied to the Anode (A) terminal, current can only flow out of the Cathode (K) terminal. The opposite is true when a negative voltage is applied; current can only flow in to the Anode (A) terminal. The diode has an intrinsic voltage drop of around 0.7V, regardless of the current flowing through it. This means that it can be used to regulate the current flow in the circuit.

The device also has several other features that make it suitable for a wide range of rectification applications. One of these is its Ultrafast recovery time, which enables the diode to switch from forward to reverse voltage extremely quickly. This allows for higher efficiency in applications such as power factor correction, as the diode can rapidly switch from rectifying one cycle of the AC voltage waveform to the next. The device also has a low forward voltage drop, meaning that it requires less power to operate.

In addition, the LSM190GE3/TR13 has a high surge current capability, which allows it to handle temporary overloads without sustaining damage. This makes it suitable for use in rectification circuits with high levels of inrush and transient current. The diode also has a high temperature coefficient, which enables it to withstand higher temperatures without suffering performance losses.

Conclusion

The LSM190GE3/TR13 rectifier diode is a high-efficiency, ultrafast device that is suitable for a wide range of rectification applications. Its high Blocking Voltage of up to 1.0kV and excellent surge current capability make it ideal for higher-voltage and transient applications, such as PC power supplies and automotive electronic systems. The device also has a low forward voltage drop, Ultrafast recovery time, and high temperature coefficient, making it an excellent choice for demanding rectification applications.
