Automotive applications include load dump protection, starter systems, electronic control units and lighting. It is also used in industrial automation, including motor drive controllers and thyristors. It is well-suited for power supply applications, such as AC-DC converters or power supplies for LED lighting.

The RF202LAM2STFTR has been used in consumer electronics due to its high current capacity and low reverse leakage current. Examples include TV and monitor displays, printers, and computer peripherals. It is also used in telecommunications systems and power line protection. Additional applications include uninterruptible power supplies and solar panel arrays.

Working Principle

The RF202LAM2STFTR is a general purpose single diode device. It has two electrodes, the anode and the cathode, connected by a metallic tunnel called a depletion region. When a positive voltage is applied to the anode, it attracts positively charged carriers to the material of the diode. At the same time, negative charges are pushed to the sides of the depletion region, creating an electrical field. This enables a current to flow through the diode.

When a negative voltage is applied to the cathode, it sends electrons to the anode, or impinges on the depletion region. This acts as a barrier to the current, and the current ceases to flow. The RF202LAM2STFTR is designed to operate in this fashion. It is able to pass high currents through its depletion layer, enabling it to be used as a rectifier or power switching device.

The RF202LAM2STFTR is protected against overvoltage and surge currents by its series interleaved junction. This ensures the RF202LAM2STFTR is able to withstand high reverse voltages of up to 200V without sustaining any damage. It also reduces thermal stress to the device, allowing it to operate efficiently and reliably in a wide temperature range.

Conclusion

The RF202LAM2STFTR is a high current rectifier diode offering excellent resistance to surge and overvoltage conditions. It is used in a variety of automotive, industrial, and consumer electronic applications. Its high current capacity and low reverse leakage current make it suitable for a range of high current operations. The device operates on the principle of creating and maintaining a reverse voltage field between the anode and cathode and is protected against overvoltage conditions by an interleaved junction.
