RSFJLHMQG application field and working principle

RSFJLHMQG are a type of single rectifier diode, often referred to as “rapid recovery” or “soft recovery” diodes. This type of diodes are widely used in high-speed applications due to their low forward voltage drop, high switching speed and low leakage current, even with high input voltages. The application fields for RSFJLHMQG diodes include logic level power supplies, automotive power systems, switched power supplies, pulse transformers and high-power audio amplifiers.

Like all other diodes, RSFJLHMQG diodes allow current to flow in one direction only, but not in the opposite direction. This is due to their composition, which consists of two different types of semiconductor material. When the semiconductor material is exposed to an electric current, it creates a field of electrons near the junction, which constitutes the diode\'s internal resistance. This resistance is very low when the current is applied in the forward direction, allowing current to flow from one side of the diode to the other, but it is much higher when the current is applied in the reverse direction, effectively blocking the current.

RSFJLHMQG diodes are different from conventional diodes in that they exhibit a much faster recovery time when switching from current blockage to current flow. This is due to their unique structure, which consists of two interdigitated layers of doped Silicon. This structure also gives them their high switching speed and low forward voltage drop.

A RSFJLHMQG diode can be used in a wide range of circuits, including high-speed switching, pulse power, high-power audio amplifiers, logic level power supplies and automotive power systems. It provides the same basic features as other rectifier diodes, including low forward voltage drop, high switching speed and low leakage current, while also offering a faster recovery time after switching.

In summary, RSFJLHMQG are a type of single rectifier diode, suitable for a wide range of applications due to their low forward voltage drop, high switching speed and low leakage current. Their unique structure allows for a faster recovery time after switching, making them an ideal choice for high-speed applications.
