The IRL8113SPBF is a low-leakage, self-protected, high-speed, low-voltage power MOSFET specifically designed for use in space-limited and energy-sensitive applications. It is an insulated-gate type device, with a small footprint and low stand-by power consumption. In general, IRL8113SPBF can be used as a switch, as a low-dropout regulator (LDO) or as a power supply for current-sensitive loads. This article will explain the application field and working principle of IRL8113SPBF.

IRL8113SPBF Application Field

The insulated-gate type IRL8113SPBF is intended for low-voltage, medium-current switching and linear applications. It is specially designed for use in space-limited areas, where it can withstand high-power loads, as well as thermal and voltage stresses. Additionally, due to its self-protection feature, the IRL8113SPBF can be used in a wide variety of applications such as automotive and industrial optimization.

The IRL8113SPBF is also suitable for power supply applications such as computer peripherals, cellular phones and other portable devices. Its small footprint allows it to fit in cramped spaces and it can be used as a power supply for current-sensitive loads, such as CMOS or ASIC chips. Additionally, its low stand-by power consumption makes it an ideal power supply for battery-operated systems.

IRL8113SPBF Working Principle

The IRL8113SPBF is a low-voltage insulated-gate type power MOSFET with built-in over-voltage protection. It uses a self-protected FET structure, which includes a series structure of two FETs and a zener diode. This structure provides the IRL8113SPBF with an over-voltage protection function—the over-voltage protection function acts as an ideal diode, which limits the voltage applied to the gate. As a result, permanent damage to the FET can be prevented.

Furthermore, the IRL8113SPBF has a low-leakage current and a fast response. The low-leakage current reduces the power consumed when the FET is in stand-by mode and the fast response helps reduce reaction time when the FET is switching from on to off or vice-versa. Additionally, the IRL8113SPBF has an internal bleeder resistor which limits the voltage across the FET when it is in off state.

The IRL8113SPBF also has a built-in protection circuit which offers an over-current protection function. This protection function helps prevent the FET from being damaged due to an over-current event. Additionally, the IRL8113SPBF has an on-resistance of 40 milliohm, which makes it suitable for switching a high-current load.

Conclusion

In conclusion, the IRL8113SPBF is a low-leakage, self-protected, high-speed, low-voltage power MOSFET. It is suitable for use in space-limited and energy-sensitive applications, such as automotive and industrial optimization. It has a small footprint, a low stand-by power consumption, a low-leakage current and a fast response. Additionally, it has a built-in protection circuit which offers an over-voltage and an over-current protection function. With these characteristics, the IRL8113SPBF is an ideal choice for low-voltage switching and linear applications.
