MCH3475-TL-E Discrete Semiconductor Products

The MCH3475-TL-E is a voltage driven n-channel enhancement mode Field-Effect Transistor (FET) composed of a power MOSFET. It is used mostly in power management and battery switching applications, as it can handle large amounts of current and power at small voltages with efficiencies much higher than traditional integrated circuits (ICs).

Application Fields

The MCH3475-TL-E is primarily used in power-switching applications, such as car battery charging and power management systems. It is also commonly used in battery back-up systems, as its low on-state operation can handle large amounts of current with a reduced power loss. The device is also suitable for lightly loaded switching applications. It is designed for low-voltage applications, such as battery-operated electronic devices.

In the automotive sector, the MCH3475-TL-E can be found in applications such as engine immobilizers, immobilizer bypasses, car door locks and keyless entry systems. It is also used as an environmental sensor switch in airbag systems, and has been used in power supplies for global positioning systems (GPS) and intelligent sensors. It is even used in military applications for guided missile systems, where its reliability and high power efficiency make it a reliable choice.

Working Principle

The MCH3475-TL-E is a n-channel enhancement mode Field-Effect Transistor (FET). This type of transistor works on the principle of electrostatic force, or electrostatics. When a voltage is applied across the gate and source terminals, an electric field is created which attracts mobile electrons. These electrons cause a small current to flow across the channel and the gate opens, allowing a larger current to flow through the device. This is known as Enhanced mode operation.

The MCH3475-TL-E is a voltage driven, polarized device, and is suitable for use with both AC and DC supplies, as well as high-frequency switching applications. It has both low input capacitance and low output capacitance for quick switching, ensuring low power losses, high efficiency and low temperatures.

The device is designed for use in harsh environments and for devices that are exposed to extreme temperatures. The package of the MCH3475-TL-E is also coated with low temperature humidity resistant surfaces, ensuring that the package is able to tolerate extreme temperatures, humidity and shocks and vibration. This makes it suitable for use in demanding industrial, transportation and military applications.

The MCH3475-TL-E has a high power efficiency, with low on-state resistance and high transfer ratio. It operates with a low power consumption and low distortion levels, providing excellent noise control. Its high speed switching and highly accurate response makes it ideal for use in high frequency switching applications.

Overall, the MCH3475-TL-E is a versatile, reliable and cost-effective FET, suitable for a wide range of power-switching applications, from automotive and industrial to military. Its low input and output capacitances, along with its high power efficiency and ultra-low power consumption make it an excellent choice for power-switching designs.
