Introduction

The FES10J is a single field-effect rectifier diode that uses a Schottky rectification principle. It has a small footprint with low-voltage power requirements and is rated to operate at ambient temperatures up to 125 degrees Celsius. This makes it ideal for applications where space and cost are of primary importance.

Construction

The FES10J consists of a single-sided Schottky diode, formed by a double single-sided PN junction, placed on a high-efficiency, insulated-gate electrode. The PN junction is formed between the center and outer electrodes, and the insulated-gate electrode connects both the electrodes to the circuit. The insulated-gate electrode has a dielectric layer that protects the gate electrode from any external electric fields and prevents it from being affected by any high-frequency noise. This structure provides excellent temperature characteristics and the ability to withstand high power loads.

Working Principle

The FES10J uses a Schottky rectification principle to control current flow. When the device is forward biased, the Schottky junction acts as an ideal diode, allowing current to flow freely. When the device is reversed biased, the Schottky junction acts as a barrier, blocking current flow. The Schottky junction has faster turn-on and turn-off times than a conventional diode, which is why it is often used in high-frequency applications. Moreover, the insulated-gate electrode prevents any external electric fields from affecting the Schottky junction. This ensures that the device operates efficiently over a wide temperature range with consistent performance, even in extreme conditions.

Applications

The FES10J has a number of different applications, including:Power-line filtering and noise suppressionSwitch-mode power suppliesDC-DC convertersDC motorsOver-voltage and reverse-voltage protectionElectronic ballastsAutomotive and off-road vehiclesThe FES10J can also be used in other high-frequency, power-conservations applications where space is a premium.

Conclusion

The FES10J is single field-effect rectifier diode with a Schottky rectification principle. It is a cost-effective, space-saving solution that has a low operating voltage and excellent temperature characteristics. It is ideally suited for applications such as power-line filtering and DC motors.
