S85JR Datasheet/PDFIntroduction
The S85JR diode is a single rectifier, an electronic component that allows electric current flow in one direction only. It\'s also known as a blocking diode or an omnipolar diode and is characterized by a very low forward voltage drop and high surge current capabilities.
The S85JR is a high-efficiency rectifier suitable for use in a variety of applications. Its construction and design make it suitable for use in converters and power supplies, as well as in telecommunications, consumer electronics, and automotive electronics. Its secondary design ensures maximum circuit protection and high-level performance.
S85JR Application Field
The S85JR diode is mainly used for rectification and for protecting against reverse current. Its use in power supplies and converters enables the incoming power from AC sources (such as a wall outlet) to be converted into direct current (DC) which is then used by the various electronic components. In addition, the S85JR can be used to provide a precise voltage reference, ensuring that sensitive circuitry will remain protected and operate efficiently.
The S85JR is also used in the automotive industry, commonly as a rectifier of car starter motor batteries. On top of that, its surge capacity allows it to be used in applications with high-energy impulse currents, such as inverters, motor drives, uninterruptible power supplies (UPS), and welding systems.
Working Principle
The S85JR is constructed as a two-part sintered body, where each part contains two junctions in a similar way as two regular diodes connected in reverse parallel. It has two anode plates and two cathode plates, with each junction being formed by one pair of anode and cathode plates.
The working principle of the S85JR is based on the junction of its two P-N junctions. The P-type region of the diode is connected to the anode, and the N-type region is connected to the cathode. When a voltage is applied to the diode, it allows current to flow only in the forward direction.
When current flows in the forward direction, electricity passes through the P-N junction, with the electrons crossing the P-N junction by a process called conduction. This is known as the forward biasing of the diode. On the other hand, when a voltage is applied to the diode in the reverse direction, the P-N junction blocks the flow of current, preventing any electrons from crossing the junction and thus blocking the current. This is known as the reverse bias of the diode.
Conclusion
The S85JR diode is a high-efficiency rectifier, suitable for use in a variety of applications, including power supplies, converters, automotive electronics and consumer electronics. Its construction and design make it suitable for use in high-energy surge current applications, such as inverters, motor drives, and uninterruptible power supplies. It is also used for protection against reverse current.
The working principle of the S85JR is based on the junction of its two P-N junctions, which allow current to flow only in the forward direction while blocking current in the reverse direction. With its low forward voltage drop and high surge current capabilities, the S85JR is a reliable, high-efficiency diode whose uses and applications continue to expand in an ever-evolving technological world.
